Description
Technical field
The invention belongs to the construction machinery in a kind of construction project field, Asia relates to and uses the seepage-proofing water-sealing wall that completes of this machinery and the construction method of various new supporting and protection structure.Having grooving concurrently, stirring into the electronic milling fluting wall forming machine of wall function of a kind of motor direct-drive specifically.
Background technology
Water seepage prevention wall technology is the indispensable important technologies such as rivers and lakes dyke building, refuse landfill engineering, Deep Foundation Pit Supporting Engineering always; in order effectively to ensure sealing anti-seepage effect, block underground hydraulic connection inside and outside construction project place so that protection of the environment better need to have a kind of desirable seepage-proofing water-sealing wall pattern and building technology thereof.At present seepage-proofing water-sealing wall pattern and the building technology thereof such as the conventional cement mixing method of industry, high pressure jet grouting stake, concrete interlocking pile, concrete underground continuous wall, owing to limit by construction equipment ability and self-technique shortcoming, all undesirable.The cement mixing method 20M depth bounds of can only constructing, when stake long when large easily because overlapping bad seepage, in the time that stratum is hard or closely knit, be not only difficult to creep into but also can make deep jag aggravation impact effect; High pressure jet grouting stake exists expanded diameter to be difficult for guarantee, the poor critical defect of sealing antiseepage reliability; The outstanding shortcoming that coagulation interlocking pile seepage-proofing water-sealing wall exists joint to leak too much and has a big risk, cost is high; In the various impervious walls of concrete underground continuous wall, cost is the highest.Build wall technology directly related with equipment.In order to build underground continuous seepage-proofing water-sealing wall reliably, domestic multiple enterprises, through introducing and innovation, have developed a series of three axles and have stirred ground-connecting-wall rig.But three axle stirrings itself also exist between stake always click joint leak more have a big risk, meet firm hard formation drilling ability strong, meet the shortcomings such as rock stratum cannot be crept into, efficiency of construction is not high, economy is good not; There is company from buying TRD engineering method rig, TCM engineering method rig, hydraulic pressure Double-wheel milling milling agitation driller abroad, spend upper 10,000,000 yuan of huge funds of several thousand ten thousand yuan even.Even the TRD engineering method rig that Shanghai Engineering Machinery Plant and Japanese enterprises are produced jointly, its price is up to 1,300 ten thousand yuan.The hydraulic pressure Double-wheel milling milling agitation driller of Shanghai development, also $ 10 million of its price. it is not just decimal that unit price crosses ten million, directly has influence on use cost.Use cost too higher position is difficult to popularize in an all-round way, affects the application about sealing support technology itself.Therefore can say, construction project field does not also have all good desirable seepage-proofing water-sealing wall construction equipment and building technologies of a kind of reliability, economy while at present.
Excavation of foundation pit and supporting are forms of construction work common in the engineering of modern urban construction.Along with town site is day by day in short supply, the foundation ditch of new excavation is often close to the existing building closing on.The soil nailing, the anchor bolt construction that when this makes pattern foundation pit supporting structure, conventionally adopt are very difficult even cannot carry out: or affect and cannot beat again anchor pole because closing on building and original pipeline; Or because not allowing anchor pole, neighbours throw its all underground soil layer into.Forced inner support method or the reverse construction adopting in this case, cost height is long in time limit.For this reason we need to find out a kind of safe and reliable, do not reduce building area and construction operation area, construction cost low new supporting method again as far as possible, meet the deep foundation pit support requirement under new execution conditions.Obviously, the floor space of Form Gravity Breast Wall is little, does not need separately to support, and is a kind of reasonably selection.But rarely seenly so far in construction, adopt, its reason is that the construction cost that adopts current apparatus and method for to build Form Gravity Breast Wall is too high.For example body of wall is all to adopt minor diameter (D500mm, D600mm) cement mixing method to build substantially at present, and due to the very stake for minor diameter of can only constructing at every turn, stake number is a lot, compares other its cost of supporting and protection structure pattern often very high.Therefore we need to have construction equipment a kind of moderate, that efficiency is high (be at least conventional equipment work efficiency tens times) to substitute traditional cement mixing pile machine, technical advantage that could real performance cement-soil gravity type retaining wall.Developing this equipment is the task of top priority.
Summary of the invention
The technical problem that we will solve is: design a kind of simple in structure, seepage-proofing water-sealing wall of low cost of manufacture, cement-soil gravity type retaining wall construction equipment, require it to use motor direct-drive, can rapidly the soil layer at deep pit digging scene be stirred into water shutoff curtain or cement soil wall, and build on this basis the supporting and protection structure of more economical reliable combined-type water earth Form Gravity Breast Wall or other type in conjunction with rear slotting bamboo reinforcement, steel etc.
The method that we solve the problems of the technologies described above is: design a kind of electronic milling fluting wall forming machine, it is by milling head, drilling rod, water booster system, guiding device forms with the walking chassis that column is housed, it is characterized in that: be placed in the water-cooled machine of recirculated water water tank by shaft coupling or gearbox, drive enveloping worm worm gear or multi-stage gear, pass through again chain, sprocket wheel drives milling wheel axle to drive milling wheel to rotate, cement paste feed pipe for mortar and high-pressure air pipe pass in drilling rod, through cyclic water tank, after coupling box or gearbox, again through the straight-through spout being arranged on outside mechanical reduction box case of mechanical reduction box, the oil pipe of a liftable flexible trim tank is passed by drilling rod after walking around the pulley at column top, sub-to cyclic water tank, coupling box or gearbox, through the bearing cover of worm screw upper end, oil pipe end is imbedded under the lubrication oil liquid level in mechanical reduction box again.Milling head casing is equipped with the anti-water jet that buries outward.Bamboo pole or shaped steel clamping insertion chuck are housed on the column on walking chassis.

Detailed description of the invention
The milling head mechanism of electronic milling fluting wall forming machine is very simple.Very clear in Fig. 1: (power of water cooled machine is large and volume is relatively little for water cooled machine 1.Can select relatively inexpensive simple alternating current generator; Also stepless speed regulation can be selected and the direct current generator that high pulling torque is more expensive can be added.) be immersed in recirculated water water tank 2, by shaft coupling 3 driving ring surface-worms 5., (coupling box herein can change a mechanical gear box into its output shaft, and operation electromagnetism deflection machine 16 drives shift fork 17 to shift gears.See Fig. 3 .) enveloping worm 5 drives anchor ring worm gear 6 and the minor sprocket 7 coaxial with worm gear, drives chain 9 hinge wheels 10 to drive milling wheel 11 to rotate.Worm and worm wheel are the simplest transmission mechanisms, also can slow down to replace worm and gear with spiral bevel gear and multi-stage gear and slow down, identical with worm and gear deceleration principle and effect.
Having a key technology herein, is exactly the sealing of milling wheel axle.When construction, milling head gos deep into the tens of rice of underground, the mechanical reduction box body to milling head is formed sizable pressure by the mixture of cement paste and sand, the two seals that silt particle and muddy water are easy to break through on milling wheel axle enters in casing, destroys the normal work of transmission system.The possibility that therefore must make the inside and outside pressure balance of casing enter casing to reduce silt particle muddy water.We,, through checking, have adopted flexible trim tank technology for this reason.Flexible trim tank 21 hangs on column rear, chassis (or be placed in after existing pile frame vertical post on running block), its oil pipe is walked around chassis column top pulleys frame, in drilling rod 15, pass, through cyclic water tank 2 coupling boxs (or gearbox) 4, through the bearing cover of worm screw 5 upper ends, finally enter worm gear case (or multi-stage gear gearbox) 8, the oil pipe port of export is inserted under the liquid level of lubrication oil in casing.This structure, make milling head more in depth under, flexible trim tank 21 position on column is higher, the oil pressure in its oil pipe exit is larger.Having avoided milling head external pressure to be greater than box house pressure completely makes muddy water enter the possibility in case.When milling head promotes, while arriving ground, flexible trim tank reduces as far as possible, thereby keeps external and internal pressure balance all the time.This is a key technology that ensures the long-term normal work of electronic milling fluting wall forming machine.
The anti-sparge pipe 14 that buries in Fig. 1 can spray High-Pressure Water in the time of bury drills, breaks up the silt particle being pressed on milling head, is beneficial to extract.Sparge pipe has 4 at least, two of every sides.
Milling wheel in Fig. 1 can be installed three, is driven respectively by three motors and transmission speed reducer structure.Three-wheel is identical with two-wheeled operating principle.But three-wheel can reduce " the hip ditch " between slot milling lowermost end milling wheel, makes that water shutoff curtain is more difficult to leak.Because each milling wheel is driven separately by a motor, so we can also install on top 2-3 milling wheel additional, manufacture four-wheel, five and take turns until take turns milling head raising efficiency of construction more.All strictly sealings between all casings of milling head.
Fig. 2 is the mechanical gear box structural representation of electronic milling fluting wall forming machine milling head.In the time that this gearbox replaces coupling box, the requirement that when mechanical speed change of realizing milling wheel rotating speed of can shifting gears enters rock or enters hard soil layer to adapt to groover, resistance increases.Should illustrate at this: only have gearshift this mechanical speed change could be with falling slow-revving way increase moment of torsion at double.This is that the hydraulic speed-changing that belongs at present permanent moment of torsion speed change cannot be accomplished.And motor only just can limitedly increase moment of torsion by frequency modulation speed change.Only, on this aspect, the performance of electronic milling fluting wall forming machine has just exceeded imported hydraulic Double-wheel milling.In the time selecting direct current water-cooled machine, can realize the stepless speed regulation that adds high pulling torque, now needn't shift gears, gearbox is reduced to coupling box.
Fig. 4 is the standard complete machine figure of electronic milling fluting wall forming machine.The hydraulic pressure Double-wheel milling of external import, price is up to more than 3,000 ten thousand yuan, the hydraulic pressure Double-wheel milling of domestic imitation, price is more than 12,000,000 yuan.And the electronic milling fluting of the present invention wall forming machine, complete machine manufacturing cost is less than 1/5 of above-mentioned domestic imitation hydraulic pressure Double-wheel milling, and function but exceedes domestic and international existing hydraulic pressure Double-wheel milling.Only there is cheapness like this and efficient construction equipment, just can make the cost of bamboo reinforced cement soil Form Gravity Breast Wall have the possibility significantly reducing.Bamboo pole clamping insertion apparatus (seeing Fig. 3) is housed on the column of standard complete machine, inserts in the cement-soil being stirred in order to clamp bamboo pole, realize do mechanization operation.Bamboo pole clamping insertion apparatus changes chuck pattern and can be used for clamping insertion shaped steel.
Fig. 5 is mounted in the electronic milling fluting wall forming machine on domestic existing pile frame.Electronic milling fluting wall forming machine directly drives with motor, does not need to set up powerful Hydraulic Station, therefore can be arranged on very easily on existing long spiral pile frame and use.But, in order to make the pile frame chassis of nearly hundred tons away from opened groove, be necessary its column top to transform, top pulleys frame lengthened (in figure 19).The bamboo pole clamping insertion apparatus of installing on it, raises drive (rouleau is raised wire rope pulley frame and is blocked in side, therefore do not draw) with original rouleau on pile frame.It is similar that in its course of work and when stake system, inserted reinforcing cage, do not need separately to employ crane.
Fig. 6 is the excavation slope sectional drawing of bamboo reinforced cement soil Form Gravity Breast Wall supporting.The about 1m of wall thickness---1.2m, floor space is very little.Its outside is inserted with the downward mao bamboon of the drilled large end of a row, and the flexural strength of refinforced cement cob wall and rigidity are made unique bamboo reinforced cement soil Form Gravity Breast Wall.This new supporting structure is not only taken up an area few, and speed of application is fast, and water shutoff gear soil is reliable for effect, and cost is very low.Even if the foundation ditch at dozen anchor pole of having ready conditions also can preferentially be selected.Especially, it should be noted that, in the past even had in small-diameter soil-cement Gravity Retaining Wall, insert mao bamboon, because cement soil mixing pile is very thick, while inserting, resistance is very large, all that microcephaly inserts down, and between mao bamboon and cement-soil, often there is gap, affected the uplift resistance of mao bamboon, its stress and effect are all bad.And the cement soil wall that adopts equipment of the present invention to build, owing to being stirred very evenly, be cement paste, can will insert with machinery greatly upside down, boring reduces hollow mao bamboon buoyancy, between mao bamboon and cement-soil, there is effective adhesive, resistance to tension is stronger, can bring into play better the inexpensive and effect of tension of mao bamboon.Bamboo reinforcement and cement-soil, be a kind of typical " Lian Lian " combination, just right, very reasonable.
Fig. 7 is the sectional drawing while utilizing bamboo reinforced cement soil Form Gravity Breast Wall to do template build permanent structure diaphragm wall.Soil layer in the middle of the bamboo reinforced cement soil of both sides can be used for grab bucket or excavator cuts out.There is bamboo reinforced cement soil retaining wall as template, make the diaphragm wall of steel concrete build very simple and convenient.
Core component " He Gelong " low speed high torque hydraulic motor of hydraulic pressure Double-wheel milling, domestic can't production at present, must dependence on import.And the electronic milling of the present invention fluting wall forming machine is pure homemade goods, although low cost of manufacture (be only 1/20 of imported product price, domestic like product price 1/5), performance exceedes imported product.
In sum: electronic milling fluting wall forming machine, simple in structure, low cost of manufacture, but owing to having adopted the way of mechanical speed change gearshift or the way of direct current generator stepless speed regulation, make it can corresponding increase output torque in the time that milling resistance becomes large, therefore functional performance exceedes imported product.With its efficient bamboo reinforced cement soil Form Gravity Breast Wall of building, can meet under the prerequisite of supporting requirement, do not consume as any steel such as anchor pole, anchor cable, supporting shaped steel.Just be conducive to energy-saving and emission-reduction as long as use no or little steel.(suit measures to local conditions.The present invention does not affect the existing shaped steel of constructor and continues to insert use).The bamboo reinforced cement soil Form Gravity Breast Wall that the present invention builds, not only low, speed of application but also fast of construction cost.Adopt present device to can also be used to build the new supporting structure such as vertical plane diagonal brace structure, π type supporting and protection structure, overcoming the shortcoming that horizontal inner support takies too much space, impact shoveling, affects Underground Construction, is a technological innovation that has distinct economic and good social effect.
