Description
The present invention relates to prepare the method for plant-growth basement rock and the spray tube that a kind of muddy that is used for this method moves the soil matrix material at soil surface in a kind of civil engineering.
More particularly, the present invention relates to a kind of method of plant-growth basement rock thin layer and method that kind of plant makes it to grow on this basement rock of preparing.When the unsuitable plant-growth of the edatope on the slope of wanting kind of plant (hereinafter claim " standard plane "), for example for sill, when containing the less soft rock of soil, sand or high clay, present method also can make plant normal growth.These slopes for example are inclined-plane and because the irrigation canals and ditches or the dykes and dams of development construction generation in the soil of injustice.The invention still further relates to the muddy that is used for this method and move the spray tube of soil matrix material.In more detail, the present invention relates to a kind ofly muddy is moved the soil matrix material spray method and the spray tube thereof that is sprayed on the face (for example standard plane) with the continuous mixture of thing (for example silk or band).Not only serike on standard plane can be used for according to method of the present invention, and serike on unusual exsiccant sand-flood can be used for.
Before this, people have known that a kind of discharge outlet from nozzle-end sprays the method for the mixture of muddy soil, by Forced Mixing in nozzle with stir the mixture and made the soil that moves of the plant-growth basement rock that contains hydrophobizing agent and air.Be ejected when according to the method, the mud earth mixtures that contains hydrophobizing agent and air lumps in nozzle.This mixture can be quite thin and firm stratiform and stick on the standard plane.
This method generally is usually used in the escarpment surface.Recently, carrying out large-scale engineering between the mountain peak, rural, expressway construction for example is so all produced not only long but also big standard plane in many places.On this not only long but also big standard plane, exist sill or special soil, be difficult to grow plant here basically.A kind of plant growth substrate, for example high-quality soil are sprayed here that thickness reaches several centimetres, so that prepare a plant growth basement rock, thereby realize a kind of nature method of vegetation again that makes.But, because the surface that will construct is the abrupt slope, the thickness of adherent plant-growth basement rock be subjected to restriction technical and economically.In view of the situation of existing this method, it is plant-growth basement rock about 10cm that people expect to prepare a kind of maximum value or maximum cms, is beneficial to serike.
With regard to the developing trend of the present method for preparing the plant-growth basement rock, for which kind of plant is this plant cultivating method introduce could forever to keep vegetation be a problem.If the herbaceous plant that plantation is easy to survive is then based on hair root.Because this can not penetrate in the soil in mountain region deeply, fertilizer will run off in several years.The growth basement rock will be degenerated owing to arid, but also may rupture with the standard plane top layer.Therefore, people wish to begin to introduce a fine variety the big plant based on main root, so that wish to grow into forest early.
Day disclosure special permission 167170/1980 discloses a kind of related art indirectly.The document has been advised a kind of method that is used to strengthen roadbed both sides or walkway, and continuously the high pressure water of ejection is being carried elongated trevira secretly from nozzle, is sprayed on the construction surface from the pressurized air of another nozzle supply and mixes with above-mentioned trevira.Also have a kind of known mortar and glass fibre to be fixed as lamellated method, use the mortar gun pneumatically applied mortar with the reinforcement road bed, and supply with glass fibre continuously, so that both converge on construction surface by the additional fibers divider with the mortar gun ejection.
With reference to Figure 13 the ordinary method of implementing according to day disclosure special permission 156170/1980 is described below.In Figure 13, in order to handle the upper surface of basic unit 40, the sand S that collects from sand-flood 50 is carried under pressure by pipe 49 by compressor 51 generation pressurized air A, and is ejected into the construction surface of basic unit 40 from nozzle 43.On the other hand, filament (fiber) T that provides from wire feeding device 54 mixes with high pressure water W that high-pressure pump 53 is got from tank 52 injector 44, and a silk T is extruded by high pressure water W and is sprayed onto on the construction surface of basic unit from the nozzle 45 of injector with high pressure water W.Have 4 among filament T(Figure 13) by the high pressure water W pore of time spent extrusion nozzle 45 successively, and be three dimensional form and on construction surface, mix with sand, thereby form hard basic unit.Like this, in the method, the fiber of filament T and sand grains S overlap independently system supply to construction surface by two respectively, so that be mixed into the mixture of fiber and grogs in construction surface.
In the prior art, in order to obtain the thin layer of plant-growth basement rock, sand and fiber overlap and spray is necessary.For the plant-growth basement rock thin layer that has firmly sprayed, the basement rock that sprays earlier needs draining and makes it to solidify, and also must spray once more then.Like this, in the method for prior art, expended the time for waiting for the basement rock draining.For improving work efficiency, this is a big defective.
The construction reference face of most of plant-growth basement rock generally has 65 °～45 ° the gradient, maximum 3～8 centimetres of the adhesion thickness of plant-growth basement rock.Adherent immediately bedrock thickness is about 3 centimetres after spraying according to the method for prior art, even also is like this when the soil of standard plane and rock have good water-absorbent.At the bad standard plane of water-absorbent, for example on clay or the rock, bedrock thickness just has only about 1 centimetre.In a word, according to the characteristics of prior art, the caking of mud is achieved, and soil becomes hydrophobic in moment.But because the draining of basement rock inside is carried out gradually, if a large amount of mud soil of continuous injection, the weight of water can increase, thereby causes the pedosphere sloughing.The emitted dose that sprays like this, each time must be restricted.
Furthermore, in the prior art, vegetable fibre is sneaked into mud soil as so-called connection material, so that make the basement rock that sprays firm.This fiber be shorter in length than 2～3cm the time, almost do not have what effect.It is long more that this connects material, and effect is just big more.But when this continuous material is sneaked into muddy when moving the soil matrix material in advance because fiber can be wrapped on the material stir shaft, curls on the axle of pressure feeding pump, sticking plug between impeller and housing, thereby cause the obstruction of pump.The length of the fiber of therefore, sneaking into is restricted.
In aforesaid art methods, the 5cm that only has an appointment is thick moves on the standard plane of basement rock that soil or plant growth substrate be adhered to unsuitable plant-growth.At this moment, stick on the standard plane even plant growth substrate for example moves soil, under the tanning by the sun of burning sun in summer, the growth base material is complete drying at short notice also.It is withered because shortage moisture, growth tender plants seedling are often dried.
According to situation recited above, prior art has adopted the clay with height water-retentivity, or plant growth substrate is mixed with water-keeping material to prevent the exsiccant method, and above-mentioned water-keeping material for example is the resin of vermiculite or high-hydroscopicity.Yet,, still can not obtain significant effect at present even used about 5cm thick any water-keeping material or clay.
People wish to introduce a fine variety big plant so that for good and all afforest basement rock and it is grown into forest as early as possible at first.But after seed was sowed, not only basement rock was done wet the variation, also had changes in temperature (Quench) variation of temperature all can influence the germination of big plant.In order to provide enough vegetative period to plant after sowing, people can not look to introducing a fine variety big plant, unless sowing was carried out in spring.Therefore, people need manage to prolong the condition in spring that is suitable for big plant seeding, and approach is to reduce because the gradient of temperature that causes in the plant-growth basement rock of the cold and hot variation of free air temperature, and prevents that moisture from evaporating from soil and mountain region.
In relevant prior art-Ri disclosure special permission 167170/1980, goal of the invention is to strengthen engineering strength by sneak into fiber in the construction surface of road or standard plane, so that solidify construction surface.Therefore, this is different from the purpose of promotion plant-growth of the present invention, by making the required muddy of plant-growth move soil matrix material caking, perhaps in construction surface, sneak into continuous thing, for example the silk or the band, form plant germination and the required suitable air gap of growth, thereby give plant-growth basement rock water-retentivity, draining and water-permeable and heat retaining property.
Yet, the continuous thing of fiber is sprayed onto construction surface and basement rock material mixing as reinforcement material, this method be similar to of the present invention.But this method and difference of the present invention are: the basement rock material is sand or mortar, is different from plant-growth basement rock of the present invention; The nozzle or the spray gun mechanism that are used to spray reinforcement material-fiber are not identical yet.In other words, according to foregoing existing method, be used for reinforcement material for example the feed mechanism of basement rock material and fiber handle respectively, and both mix on construction surface.Like this, after basement rock material and reinforcement material mixing, both cementabilities are also bad.Therefore, can not look to construction surface to obtain good firm stiffening effect.
According to existing method, the water purifying spraying pressure will be extruded from jet orifice with the essentially identical fiber of jet size, for example use the high-pressure pump jet fiber, make it to be sprayed onto on the construction surface.About 200 microns of the thickness of above-mentioned silk, because the nozzle diameter of nozzle is less, nozzle is blocked easily.Even fiber under high pressure sprays, its flying distance is not long yet, in fact for example has only 2～3cm.The work of big standard plane for covering a block length, this is unfavorable.
So, the purpose of this invention is to provide the spray tube that a kind of a kind of muddy for preparing the method for plant-growth basement rock and be used for this method moves the soil matrix material, they can be eliminated aforesaid the problems of the prior art and solve technical problem to be solved, the method of the mixed injection device by using slurried material and fiber, obtain the firmly construction surface of reinforcement, in each the injection, can use big as far as possible emitted dose and can obtain big jet length, and make above-mentioned construction surface have good water-retentivity, heat retaining property, draining and ventilation property.
Underbalance effect sucks a cylinder with atmosphere, and this underbalance effect is owing to producing above-mentioned cylinder from the spout ejection at the inner plant-growth basement rock of jet pipe inlet mouth material-mud.Thread, the rope form or the banded thing continuously that insert inlet mouth from the outside attracted to the cylinder of jet pipe with air.Muddy plant-growth basement rock material mixes in this cylinder with above-mentioned continuous thing, and is carrying continuously the thing jet pipe that flies out secretly from the relief outlet of nozzle-end, and both are mutual miscellaneous state and adhere on the construction surface.At this moment, jet pipe is buried in the plant-growth basement rock so that make continuous thing be netted, thereby has reinforced construction surface by the left and right directions swing up and down of predetermined amplitude.Improved the water-retentivity of above-mentioned basement rock thus, draining and water-permeable.
When hydrophobizing agent injected the cylinder of jet pipe, hydrophobizing agent, slurried material and air mixed stirring in cylinder, so that separate water outlet by the effect of hydrophobizing agent from mud, the coagulating sludge material.Then, the plant-growth basement rock material of caking is being carried above-mentioned continuous thing secretly and is being flown out from the jet pipe relief outlet, and adheres on the construction surface.At this moment, because plant-growth basement rock material is formed piece, the basement rock material is intertwined with connector preferably after spraying construction surface, thereby has further improved water-retentivity, draining, ventilation property and the heat retaining property of construction surface, has reinforced this basement rock thus.Furthermore, the flying distance from the matrix material of jet pipe ejection has also extended.
The method that the continuous thing of the fluid-tight band shape of a kind of spray feed is with film to cover to the surface of basement rock with the good plant-growth basement rock surface of covering prepared beforehand will be described below.This method has identical effect with membrane covering, and agglomerative dew or moisture evaporate from the soil on the mulch film lower surface that all is used for preventing causing owing to the free air temperature lifting, thereby have prevented drying.Covering a kind with straw or a plastic film has the farmland of seedling or broadcasts seed-bearing soil, perhaps on the dry land of a slice, for example covers a plant-growth surface en bloc with film in the desert, can obtain above-mentioned effect.Here, band-like film is used for covering a sty or a common vivifying uneven surface and does not exist with uneven surface concavo-convex accordingly.
Be blown into plant-growth basement rock surface with being stained with aluminium foil, aluminium powder and having the continuous thing that the waterproof band of heat bundle reflecting element makes, cover this surface.Have cold and hot variation even cover the back free air temperature, because heat bundle reflex action is arranged, the lifting of plant-growth basement rock temperature inside has been slowed down, and the moisture evaporation of mountain soil also is prevented from, thereby has prolonged the time that is suitable for sowing plant seed.

Fig. 1 represents that wherein Fig. 1 (a) is the outward appearance front view of a width of cloth jet pipe according to plant-growth basement rock injection of material pipe 10 of the present invention, and Fig. 1 (b) is the sectional view of the major parts of this jet pipe.
Fig. 1 (a) and 1(b) in, label 1 expression muddy moves the spout of soil matrix material M, cylinder that is installed on spout 1 end of label 2 expressions, this cylinder interior has some agitating vane 2a.This cylinder 2(hereinafter claim " mixing drum ") can not be with agitating vane 2a.Label 3 expression inlet mouths, label 4 are insertion guide holes of fiber (for example silk) the continuous thing T of shape, and this hole connects arrival mixing drum 2 by inlet mouth 3.When the quantity in hole 4 along the circumferential direction increased, two or more filament T can feed mixing drum 2 simultaneously, so that increase the silk T mixed volume among the plant-growth basement rock material G.Label 6 expression earth are sewed and are prevented lid.The relief outlet of label 7 expression jet pipes 10.The muddy of a spherical valve of label 8 expressions moves soil matrix material regulating cock.One of label 9 expression is connected to the rubber hose on the transfer pump (not shown) that muddy moves the soil matrix material.The spool of the continuous thing T of label 14 expressions.
In construction surface, a kind of method for preparing the plant-growth basement rock of implementing with the slurried material spray tube of said structure on the standard plane for example.In this method, the working process of jet pipe will be described.The muddy of being carried under pressure by a muddy materials supply pump (not shown) moves soil matrix material M and delivers to spray tube 10 by a slat gum pipe 9, move the regulating cock 8 of soil matrix material with mud and suitably regulate supply, subsequently, base material M arrives spout 1, and sprays into mixing drum 2 from spout 1.Because jet action has produced negative pressure in the ingress of mixing drum 2, air A sucks in the mixing drum through inlet mouth 3 thus.By means of the suction of air, continuous thing T, for example silk thread is attracted, and passes the continuous thing insertion guide hole 4 that communicates with inlet mouth 3 from spool 14 and enters mixing drum 2.Slurried material M, air A and continuous thing T are mixed into mixture in this mixing drum 2, preferably contact stirring with agitating vane 2a, so that form plant-growth basement rock material G.Material G sprays to construction surface through relief outlet 7.So, because filament and earth stir into mixture preferably in same jet pipe before ejection, both spreadabilities (bond stress) thus be enhanced and form a kind of stable substrate.The size of the insertion guide hole 4 of this or analogue is more much bigger than the wire hole of (Figure 13) in the prior art.Therefore, this hole is not in use stopped up.The relief outlet size of this jet pipe is also big, thereby outlet pressure is big, and the flying distance that is sprayed onto the plant-growth basement rock on the construction surface when spraying is longer than prior art greatly, the engineering of big standard plane for handling a block length, and this is desirable.
Additional embodiments of the present invention is described below with reference to the accompanying drawings.
Fig. 2 is an explanatory, when expression sprays plant-growth basement rock material and continuous thing when plant-growth basement rock spray tube, and the main working parts of jet pipe.The difference of the spray tube 10 among Fig. 2 among spray tube 20 and Fig. 1 is: jet pipe 20 has hydrophobizing agent filling orifice 11, and the other parts of this jet pipe 20 and jet pipe 10 are basic identical.Wherein the total part identical with jet pipe 10 represented with identical label on the jet pipe 20.
In the structure of the spray tube 20 of plant-growth basement rock material, a mixing drum 2 is installed to the end that is the throttling shape of slurried material spout 1.On this mixing drum 2, also be provided with 11, one inlet mouths of a hydrophobizing agent filling orifice and an end relief outlet 7.Some agitating vane 2a are arranged in the mixing drum 2.On the other hand, thread, rope form or zonal continuous thing T are on bobbin 14, and this continuous thing T is transferred and passes a filament and insert lead ring 5 and inlet mouth 3, then, from end relief outlet 7 sprays of this jet pipe 20 from jet pipe 20.
In said structure, muddy move soil matrix material M under pressure by the supply of a pump (not shown), enter spout 1 along the arrow direction, slurried material M sprays into mixing drum 2 through spout 1 under the crunch effect.By means of the underbalance effect that jet in the mixing drum 2 causes, air A sucks mixing drum 2 from inlet mouth 3 by suction.In this case, this continuous thing T transfers to the direction of arrow of inlet mouth 3(along dotted line from roll 14), and mix with plant-growth basement rock material G, then, both outwards spray from the end relief outlet 7 of spray tube 20 simultaneously.
This continuous thing T is guided into mixing drum 2 easily by the pulling force of the air that is inhaled into.This continuous thing T is not limited to only one.People can be provided with two or more inlet mouths 3, so that guide two or many continuous thing T respectively; Perhaps, two or many continuous thing T also can import from an inlet mouth 3.
Hydrophobizing agent F is carried under pressure by a pipe 12 by a pump (not shown), so that hydrophobizing agent injects mixing drum 2 from hydrophobizing agent filling orifice 11.Slurry material M, hydrophobizing agent F and air A mix stirring in mixing drum 2, muddy moves soil matrix material M and lumps herein, become a plant growth basement rock material G.
In the present invention, muddy moves the soil matrix material and is used as soil base material, and fertilizer, seed and/or rhizome suitably mix with it, and in case of necessity, vegetable fibre and/or sanitas also can be sneaked into.For the preparation slurry material also will be mixed an amount of water.
The hydrophobizing agent that is injected into comprises: for example HYDROLYSIS OF POLYACRYLAMIDE AND ITS COPOLYMERS product or analogue.This material has the dried up effect of branch, it act on muddy move soil matrix material M make it the caking.
As the continuous thing T of maximum characteristics of the present invention is thread, rope form or zonal continuous elongated thing, and its shape is not limit.If but its weight is excessive, it will be not suitable for moving soil matrix material M with muddy mixes, and promptly in the caking process in spray tube, plant-growth basement rock material G can be scattered and fall on the way.According to the present invention, low weight continuous thing T suits.
In injection work, spray tube 20 is embedded in the plant-growth matrix material so that continuous thing T is nettedly, thereby firmly is bonded on the standard plane with the left and right directions swing up and down of predetermined amplitude.So the soil layer B that moves of one deck caking forms on standard plane, shown in Fig. 3 and 4.Fig. 3 is a width of cloth decomposition elevation, when expression is sprayed work according to present embodiment, and the main component of moving soil layer B of the caking on standard plane.Fig. 4 is the proximate cross-sectional side view of moving soil layer B of width of cloth caking.Shown in Fig. 3 and 4, continuously thing T is netted in short transverse and transversely buried, plant-growth basement rock material G adhesion ground repeatedly pile about thing continuously, thereby constitute lump move soil layer B, this moves soil layer B securely attached on the standard plane K.At this moment, continuously thing T can absorb and seal the moisture of hydrophobic treatment, and when mud lumpd, it is interior so that keep moisture for a long time that these moisture accumulate in the air gap of continuous thing.Air infiltrates from being exposed to some position of moving soil layer B surface, and enters into the inside of moving soil layer B by the air gap of continuous thing, thereby has realized ventilative.
Fig. 5 represents that continuous thing T sneaks into the local enlarged view of the state among the plant-growth basement rock material G.As shown in Figure 5, the plant-growth basement rock material G of caking is the agglomerate that plurality of single grogs P gathers, and material G mixes with the continuous thing T that is absorbed among the grogs P.Therefore, some grogs support mutually with continuous thing, are keeping preservation water and gas-pervious many gaps between them.
As previously mentioned, continuously thing T sneaks among the injected plant-growth basement rock material G with three dimensional form, mixes mutually and is supporting the plant-growth basement rock material G that will glide.Therefore, spray thickness through injection work once and just can increase to 10cm or bigger, thereby prepare firm plant-growth basement rock expeditiously, thus, the gradient of standard plane, soil and rock how no matter improved efficient greatly.
According to the situation of standard plane, the swing of this spray tube 20 can be not always be carried out about up and down.For example: if standard plane is very uneven, spray tube 20 only swings, thereby the continuous thing of move left and right is just passable, realizes goal of the invention thus.
When using, can further obtain excellent anti-slump effect through anti-skidding processing or the continuous thing T that snarled easily.
When shape that designs continuous thing T and intensity, people can look to various operations and effect.For example: when use had high-tensile continuous thing, people can look to being prevented the effect of standard plane fracture.
In other words, for being stablized, the plant-growth basement rock that sprays lives and prevents the little fracture of standard plane generation at present, base net of being made by rhombus skeleton wire netting or artificial resin net (see Fig. 7 23) was laid on the standard plane earlier before spraying operation, and then on it injection plant-growth basement rock material.In the method for the invention, when the shape of continuous thing and intensity are designed, and this continuous thing is netted when being buried in the plant-growth basement rock, and the base net of laying in the prior art can omit.
When people use Fig. 6 (a) to 6(e) shown in be the banded thing continuously of bilayer or multilayer folding state the time, the water-retentivity and the ventilation property of plant-growth basement rock inside can improve.Fig. 6 has represented some samples that are suitable for, wherein Fig. 6 (a) represents three overlapping states of band, the two-fold state of Fig. 6 (b) expression band, Fig. 6 (c) represents tubular state, Fig. 6 (d) represents a fibrous bundle, the fibrous bundle of Fig. 6 (e) expression irregular folding is expressed as some holes that water-permeable and air permeable is opened with reference to mark h on continuous thing.
More particularly, be generally precipitous basement rock for being suitable for the standard plane that plant-growth sprays plant-growth basement rock material, and some plants that in the basement rock of limited several cm thicks, growing.Therefore, the water retention property of basement rock has fundamental influence to the growth of plant.Because construction surface generally is the standard plane of leveling off hilltops and staying, the water that trickles between the mountain flows through from standard plane, thereby is always wet in some places.Basement rock at wet place is in anoxic condition by water saturates, and this will damage the growth of plant.
For serike in the limited plant-growth basement rock of thickness even in hostile environment, the formed plurality of gaps of folding has realized the raising of water-retentivity, drainage, ventilation property etc. when burying banded thing continuously of aforesaid bilayer or multiwalled or analogue according to method of the present invention.Therefore can look to during plant-growth, always keeping good envrionment conditions.
Article one, flat (the banded rectangular thing) that is surrounded by (being stained with) aluminium foil is used as continuous thing T so that reduce temperature difference in the soil.Like this, atmosphere temperature-difference can alleviate the influence of plant-growth basement rock inside, thus alleviated winter severe cold, summer burning sun extremely hot influence to basement rock inside.Therefore, transformed the season that is not suitable for plant-growth artificially, and the time that is suitable for plant-growth can prolong.
Making the result of experiment example according to the present invention narrates below.In this experiment, mud moves the mixture that the soil matrix material adopts following compositions:
Orchard soil (containing fertilizer): 2500 liters
Vegetable fibre: 960 liters
Chemical fertilizer: 40 kilograms
Sanitas: 90 liters
(special asphalt emulsifier etc.)
0.7 kilogram in seed (Kentucky 31F, etc.)
When spraying thickness when being 10cm, said mixture is to spray 30m
2The consumption of area.
Filling 2000 premium on currency in the base material water tank (4000 liters of volumes) that sprays machinery mix said mixture then with water, become mud through stirring.
On the other hand, 600 gram hydrophobizing agents (hydrolysis of polyacrylamide product) dissolve in 300 premium on currency in hydrophobizing agent water tank (300 liters of volumes) lining, are prepared into concentration and are 0.2% the aqueous solution, for above-mentioned mixture use.
What thing was used continuously is 2000 meter one volume, polyethylene bands 6 mm wides, 200 grammes per square metres.
As shown in Figure 2, slush pump moves soil matrix material M to spray tube 20 supply muddies under pressure, until its spout 1.A toothed gear pump carries hydrophobizing agent F to hydrophobizing agent inlet 11.The end that polyethylene is flat inserts inlet mouth 3 through lead ring 5, enters mixing drum 2.Spool 14 freely rotates so that the polyethylene band is provided.
When injection beginning, the jet flow negative pressure that is moved soil matrix material M by muddy sucks spray tube 20 to air from inlet mouth 3.In mixing drum 2, the jet that muddy moves soil matrix material M mixes hydrophobizing agent F and air A, and forces to stir.Then, at this moment base material M conglomeration, is separated again for improving the water that flowability that muddy moves soil matrix material M adds in the base material water tank in advance, makes base material plasticising, thereby is transformed into plant-growth basement rock material G.At last, G outwards sprays from relief outlet 7.
On the other hand, under the air suction, import mixing drum 2 from the above-mentioned polyethylene band that inlet mouth 3 imports, and under the discharge impulse action of plant-growth basement rock material G, fly out from relief outlet 7 therewith.And the polyethylene band is three dimensional form (spatial) and mixes among the plant-growth basement rock material G be embedded on the standard plane, sticks into admixture.
At this moment, the operator adjusts the scope that sprays on the standard plane as wide as possible with hand left and right directions swing spray tube 20 up and down significantly, up and down and about be about about 10m.
In this method, the polyethylene band that flies out with plant-growth matrix material G is sticked into the netted of complexity, imbeds agglutinating plant-growth basement rock inside.
In this case, concerning a muddy move soil matrix material M spray machinery water tank (4000 liters of volumes), the consumption of polyethylene band is about 2500 meters.Obviously, the swing mode of this consumption and jet pipe is irrelevant.
In this experimental example, the standard plane gradient that spray is 65 °, has formed the thick plant-growth basement rock of about 10cm through once spraying, and above-mentioned basement rock slump not at all.
In the prior art, run into so precipitous standard plane, the thickness that sprays that once sprays only is 3cm or just slump downwards of plant-growth basement rock when more.So prior art, need spray 3～4 times can finish the work, and all will wait for draining at every turn.Form contrast therewith, method of the present invention can be carried out the preparation work of plant-growth basement rock with high efficient.
In this experiment, only used a polyethylene band.But, when two or more inlet mouths are arranged, can use two or more polyethylene band fully simultaneously on spray tube.
According to the present invention, spray because mixing with the continuous thing T of fiber-like that inserts mixing drums 2 from inlet mouth 3, so after mixture was sprayed onto standard plane, continuous thing T was with gravel drape well from the muddy material of spout 1 ejection.In order to measure the drape effect with gravel, people have carried out following measurement.Specifically, serve as the macrofiber of continuous thing T, after spraying, this fiber is pulled out from the surface of adhesion lentamente, measure the adhesion quantity of gravel then with non-flammable polyester multi-filament.As a result, in the prior art, when silk (fiber) and gravel spray from nozzle separately respectively, the gravel of not adhering on most fibers.And according to the present invention, fiber and gravel mix in the mixing drum of jet pipe and then spray, and fiber and gravel mix, and are adhering to a large amount of gravel on the fiber.Measuring result such as table 1 are listed.

(the present invention)
The length of tested fiber is 1m * 5.(1) the expression fiber is adhering to the weight of the fiber of gravel when the face of spraying is removed; (2) expression is in gravel from the fiber the weight of the fiber of naked state behind the flush away; Above-mentioned (1) and (2) are all measured.(3) expression adheres to weight=(1)-(2) of the gravel on the fiber, and this value is measured so that show the degree of adhesion of gravel on fiber, i.e. the fiber drape effect of gravel.As the listed result of table 1, gravel (moving the soil matrix material) is sprayed onto construction surface with filament from a jet pipe, and this method can make filament adhere to more gravel, obviously, is adhering to the drape better effects if of the filament of gravel.People also will understand, and the tension force of filament is enough to a kind of like this effect of realization, thereby exerts pressure and pulling force to gravel on construction surface, compare with existing method, and the tension force of filament can keep the intensity of basement rock, and keeps its stability.
Because the spray tube of slurry material of the present invention is supplied mud by the big slush pump of liquid-conveying amount under pressure, and from the heavy caliber spout ejection that is 20mm of a diameter, so the flying distance of muddy soil is about 20m.The macrofiber of the continuous thing of blended is also fallen the place that muddy soil is scattered thereupon with it.The quantity of increase and gravel blended water is with the slurry material of preparation lower concentration, and spray this mud thing so that improve the conveying liquid head (pressure) of the slush pump of carrying liquid, at this moment, the spraying pressure of jet pipe improves thereupon, and in contrast, flying distance is but because the material spray is dispelled by atmospheric drag behind jet pipe and shortens.
So in the present invention, mechanism's (hydrophobizing agent inlet) of mixing hydrophobizing agent (agglutinant) F is arranged on the mixing drum 2, this mixing drum is installed in the end of slurry material spout 1.The jet pressure of slurry material makes air suck from inlet mouth 3, and in breathing process, slurry material M and hydrophobizing agent F are admixed together.This muddy material M and as the air A of contact substance cohesion, used water when isolating preparation slurry material M, thus make slurry material M caking, prevented successfully that thus the slurry material of leaving jet pipe is scattered.
The gravel of plasticising of separating from water and caking can fly under the situation of not being scattered 30～40 meters.During caking, fully closely mix, and the gravel of 30～40 meters of following of whole journey flights flies together, and stably be bonded in the gravel with three dimensional form with gravel with slurry material M blended successive macrofiber.
Following handle is listed in the table 2 according to the comparative result of the flying distance observed value of the filament of present method:

In table 2, according to the method for prior art, from the hole of diameter 1mm, spray 1 premium on currency, make filament flight with spraying pressure.
In method of the present invention (1), 2000 premium on currency mix with 2500 liters of mud soil, are prepared into slurry material.Use 17kg/cm
2High pressure slurry pump slurry material and successive macrofiber are sprayed together, do not make the slurry material caking described and do not resemble claim 2.
In method of the present invention (2), 600 liters of concentration be 0.2% polyacrylamide solution as hydrophobizing agent, sneak into jet pipe by the described method of claim 3.The whitewashing material with as the air of contact substance mutually in the agglomeration process, the successive macrofiber gushes out.
Listed as table 2, according to the present invention, the flying distance of filament of the prior art can be enlarged 10 times.The work of carrying out on for example not only long but also big standard plane of construction surface can be carried out expeditiously.
The internal diameter of the mixing drum 2 of jet pipe reduces, so that spray slurry material from slurry material ejiction opening 7 under pressure.In order with underbalance effect successive macrofiber T and air A to be sucked together, the size of inlet mouth 3 is that diameter is 5～6 times of mud nozzle 1 of 2cm.Like this, can eliminate because the too small exotic that causes of the jet size of continuous fiber stops up the phenomenon of spout.Furthermore, can spray the fiber with different diameter of any amount easily with a jet pipe.
In the embodiment previously described, when the hydrophobizing agent valve 13 of spray tube 20 closed, stops to inject hydrophobizing agent F from hydrophobizing agent inlet 11 in mixing drum 2, the condition of this embodiment was just identical with the embodiment of claim 1 and 3 described use jet pipes 10.Concerning identical condition, what obtain also is similar effects certainly.
In the present embodiment, for the water-retentivity on the plant-growth surface of improving the plant-growth basement rock, a kind of fluid-tight band is sprayed onto and sticks to the plant-growth surface.At this moment, in order to increase the flying distance of ribbon, the muddy of the emulsion of binder aqueous solution or tackiness agent or dilution moves the soil matrix material and is used to replace embodiment used muddy in front to move the soil matrix material.Among the embodiment in front, main purpose is the stability of moving the soil matrix material that sprays, and in the present embodiment, its objective is and will realize a kind of band membrane covering method, with banded film cover plant growth basement rock, forms a band film coating.Purpose in view of the above, the band film that need dish out at a distance and be stained with solution or slurry material, fitly big area is laid thin band film.Thereby, in the present embodiment, do not use two-fold or the triple-lap band, and the width of used wall scroll band is about 2cm.
A concrete instance of present embodiment will be described below.Spray tube adopts described jet pipe 10 of claim 1 or the described jet pipe 20 of claim 2.Hydrophobizing agent fillup valve 13 in the jet pipe is closed, so that spray 4000 liters of mud.Jet sucks the wide tape of the long 2cm of about 2500m (flat sand), makes it to spray and stick on the construction surface with solution or slurry material.
In the present embodiment, 4 wide bands of 2cm are inhaled into, and are sprayed onto 200m with 4000 liters of solution or slurry material
2Standard plane on, and adhere to thereon.In the calculating, 4 wide bands of 2cm are inhaled into and every band ejection 2500m length, therefore can be calculated as follows:
2cm×（2500m×4）＝200m
2
Therefore, when fitly spraying, four bands are attached to 200m
2Standard plane on the time, be 100% band tectum with obtaining fraction of coverage.But because these tapes in fact can be overlapping somewhere, after the construction, visual fraction of coverage is about 60～70%.Provide water retention on this level of coverage, also can form some suitable clearances simultaneously, these air gaps can not cause adverse influence to rudiment and the growth of plant.
The actual result of the test job (test work) of spraying tape will be described below.
Situation when using binder aqueous solution is at first described.The mixing element of the binder aqueous solution that uses in this test operation is as follows:
Tackiness agent (the Japanese Dai-ichi Kogyo Seiyaku of Highset 200 company limited produces) 2kg
Sanitas (Furincoat, Royal Dutch Shell company limited produces) 180kg
4000 liters of fresh water
With a pump (not shown) under pressure with above-mentioned aqueous solution input spray tube 20(Fig. 2), and be sprayed onto the test site at tape T this aqueous solution when inlet mouth 3 sucks.Because in current test work, do not use hydrophobizing agent, so hydrophobizing agent valve 13 has cut out hydrophobizing agent inlet 11.
Test situation when using muddy to move the soil matrix material will be described now.To move the mixing element of soil matrix material as follows for muddy in the current operation:
1250 liters of orchard soils (containing fertilizer)
480 liters on vegetable fibre
45 liters of sanitass
4000 liters of fresh water
This time increase in the test and used hydrophobizing agent, this hydrophobizing agent comprises following compositions:
600 liters of hydrophobizing agents (hydrolysis of polyacrylamide water thing)
300 liters of fresh water
With spray tube shown in Figure 2 20 above-mentioned muddy is moved soil matrix material and hydrophobizing agent and be ejected into the construction surface in test work district with the tape T that sucks from inlet mouth 3.At this moment, drain valve 13 is opened, and hydrophobizing agent injects in the mixing drum 2 from hydrophobizing agent inlet 11.
Above-mentioned two types compounding substances is ejected into growing surface by pump and jet pipe separately.A plantation surface of this test site at first is described, as shown in Figure 7, the soil matrix material that moves that 10cm is thick is ejected on the standard plane 21 of basement rock as a plant growth basement rock, thereby makes standard plane 26.Base net 23 and pricker 24 that standard plane 26 usefulness wire nettings or resin web are made are fixed on the standard plane of basement rock.Vegetable material for example seed 25 or similar physical in standard plane 26.With regard to another growing surface, as shown in Figure 8, a seed sprinkling of preparation thin layer 27(comprises for example seed 25 of vegetable material on standard plane 22), this standard plane 22 is as the easy drying of sand.Then, binder solution or muddy move the soil matrix material and are with 31 to be ejected on above-mentioned standard plane 21 and 22 with fluid-tight, form a kind of band film coating 35.By spraying the district place that is not sprayed is fully arranged, it is provided as the not works in progress in the some works in progresss.Every 200m
2Gather the 100cc soil four positions with the soil collectors on the area, these soil samples are picked up from the works in progress and plant-growth basement rock and 2 centimetres of sands on the surface of the not works in progress that is adjacent.With above-mentioned soil sample under 100 ℃ temperature dry 24 hours, measure water content (weight ratio of contained humidity) then, thereby obtain the soil moisture content of four positions in the every works in progress, and calculate mean value.The continuous result who measured in tens days is presented at Fig. 9 (a), 9(b) and 10(a), 10(b) in.Fig. 9 represents the sort of situation shown in Figure 7, the moisture preserving property curve when promptly being attached on the plant-growth basement rock with the film spray, the situation when wherein binder solution is used in Fig. 9 (a) expression, the situation when slurry material is used in Fig. 9 (b) expression.Figure 10 represents the sort of situation shown in Figure 8, the situation when promptly spraying on the sand with film, the situation when slurry material is used in Figure 10 (b) expression.Can find out obviously that from Fig. 9 and 10 test site of use binder aqueous solution demonstrates than the test site that uses muddy to move the soil matrix material has better water conservation effect, but both result differences and little.Along with the passing of fate, two test sites are all in drying, and its water content is reducing gradually, but its water content still remains on 18～20%, and the both is not dried to the degree of water content 15% this infringement plant-growth.On the contrary, the non-works in progress that does not cover above-mentioned substance is then dry soon, and after 15～20 days, moisture content is reduced to 13% this initial withering below the value, and by contrast, the effect that sprays the band film of the present invention can be observed significantly.Those zones that sprayed and measure are that some construct the smoother standard plane on the table plane.But the situation of using muddy to move the soil matrix material is compared with the situation of using binder solution, and the former more positively sticks on the very uneven standard plane ribbon, and the possibility that ribbon is blown to four winds is also littler.
Various details is according to claim 7 and 8 described two other embodiment.The difference of claim 7 and 8 described embodiment and claim 5 and 6 described embodiment is: the latter only uses a kind of fluid-tight band as used band film, and this two embodiment uses aluminium foil, aluminium foil that has heat bundle reflecting element or the waterproof band that is stained with aluminium foil.Other conditions all embodiment with the front are identical, therefore, will omit description.
The example of these embodiment of various details.These test example freeze-up (February 1) and extremely hot times in summer (August 1) in the winter time carry out twice altogether.In this twice test work, the waterproof band with heat bundle reflecting element moves the ejection of soil matrix material with muddy.Similar with the embodiment of front, the plant-growth basement rock is also sprayed in the test site of construction, and according to these embodiment, the plant-growth basement rock is sprayed the plant-growth matrix material in advance.After the work of spraying, measure the temperature of basement rock continuously half a year.Its result is illustrated in Figure 11 and 12, T among the figure
