Abstract
The invention discloses a greening method of a cement mortar anchoring and shotcreting side slope, comprising the steps of paving root-system induction holes on the cleaned cement anchoring and shotcreting side slope; setting ecological rods along the contour line; paving and anchoring vegetation cushions, ecological rods and geotechnique grille nets in ecologic rod lattices; and then spraying and sowing vegetation base layers and seed layers, finally covering vegetation blankets. Through the method, the cement mortar anchoring and shotcreting side slope is greened, so that the weathering and stripping of the cement mortar layer exposed in air for a long period can be avoided; the protection effect of the side slope engineering can be enhanced; and the long-time stability and safety of the slope surface can be ensured; meanwhile, the method solves the problem that the artificial planting layer on the cement mortar anchoring and shotcreting slope is eroded by rainfall to slip, fall off and the like, so that the stability of the planting layer can be ensured and a stable base is ecologically provided to the slope vegetation.
Description
Technical field
The invention belongs to the ecological reestablishment field, relate to a kind of cement mortar anchor spray side slope ecological renovation method.
Background technology
China's economic development in recent years is swift and violent, and infrastructure constructions such as highway, railway, water conservancy and municipal administration are maked rapid progress.Yet cut into a mountain in a large number in the process of construction, quarry, form a lot of expose domatic, be stability and the safety of guaranteeing slope project, the slope project technical measures that often adopt both at home and abroad are exactly to excavating the domatic cement mortar combined bolting and shotcrete that carries out.Because the domatic influence that receives natural causes such as ultraviolet ray, sunlight, water erosion, wind erosion for a long time, very easily take place the top layer mortar weathering, peel off, even cave in; Influence the stability and the safety of slope project; Cement mortar has very strong heat absorptivity simultaneously, and heat island effect is obvious, has both diminished ecoscape; Increase energy consumption, also run counter to modern society environmental protection requirement.
Cement mortar anchor spray greening side slope is focus, the difficult point that industry is paid close attention to always; Though some technology are arranged at present to be used; But owing to receive the restriction of domatic land occupation condition, weather conditions and execution conditions, construction quality is difficult to control, more is difficult to satisfy extensive slope revegetation engineering construction.
Summary of the invention
The purpose of this invention is to provide a kind of cement mortar anchor spray method for greening side slope.
Cement mortar anchor spray method for greening side slope provided by the invention, it comprises the steps:
1) the cement mortar side slope surface is cleared up, the place that domatic detrition is serious is removed or is reinforced, and cleans domatic;
2) through boring root system is set on domatic and induces the hole;
3) be the isohypse of 1.5-3m along spacing, on domatic, hole that boring direction is perpendicular to domatic, insert anchor pole and, ecological rod is set above the anchor pole exposed parts, ecological rod is fixed on the anchor pole, form ecological excellent sash with the cement mortar anchoring of being in the milk;
3) living pad is planted in laying in the excellent sash of domatic ecology, and fixes with rivet;
4) lay earth work grille net, with anchor pole with earth work grille net, plant give birth to pad be fixed on domatic on;
5) plant living substrate layer and seed layer online successively the sowing grass seeds by duster of GSZ;
6) at seed layer surface coverage vegetation blanket.
Wherein, step 2) to induce the aperture in hole be 10～20cm to described root system, and the degree of depth is 20-50cm, 3～8 of every square meters.
Wherein, the aperture in the hole of being bored in the step 3) is 3～5cm, and the degree of depth is 20～30cm.
Wherein, anchor pole length is 5-100cm in the step 3), preferred 15-100cm, and diameter is 6-36mm, preferred 9-25cm.
The thickness of planting living substrate layer of wherein, sowing grass seeds by duster is 5～10cm.
Wherein, the thickness of the seed layer of sowing grass seeds by duster is 2～4cm, is preferably 3cm.It will be appreciated by those skilled in the art that seed layer comprises plants living base material and seed, and those skilled in the art can select suitable grain weight as required and plant subcategory.The living base material of planting in the seed layer can be with to plant the living base material of planting of living substrate layer identical or different.
Describedly plant living substrate layer and comprise in biological compost, inorganic mineral, soil, an agent, water-loss reducer, adhesive and the slow-release fertilizer one or more.
Of the present inventionly plant that to give birth to pad be that pad is given birth in conventional used the planting in this area, form, sew up the formation cushion through the graticule mode by domatic water draining and accumulating layer, greening substrate layer and surface coating.Domatic water draining and accumulating layer is processed by the water permeability composite material, surface coating is made up of the natural plant fibre net, but is natural degradation.The present invention lays to plant on side slope and gives birth to pad, and pad is given birth in this plantation can increase roughness, improves the adhesive strength of planting living substrate layer.Simultaneously; Can retain, dredge the interflow in the planting layer effectively; Promote the unnecessary precipitation that penetrates in the planting layer to discharge fast, effectively reduce the lubrication of domatic of planting layer and anchor spray, and can store a certain amount of rainfall; Strengthen domatic base material stability, effectively improve the slope vegetation growth conditions.
Ecology used among the present invention is excellent, and it is processed by non-degradable plastics (PP) material, has good flexible and tensile strength, has the permeable soil characteristics of not passing through simultaneously.Can process the tubulose (bag shape) of different size according to actual demands of engineering, filling has good physicochemical property in it, satisfies the living base material of planting of plant growing needs.In engineering is used, can play auxiliary reinforcement (sash) effect, carry out small classification to domatic simultaneously, can effectively alleviate rainfall washing away domatic planting layer.
The used earth work grille net of the present invention is processed by non-degradable plastics (PE, PP) material, and general mesh size is 4cm * 4cm.Have good flexible and tensile strength, in engineering, play reinforced action, guarantee that planting living substrate layer adheres in domatic long-term stability.
The present invention is used plants living base material, and it is the core material of slope greening technology, is that media base and the required moisture of plant growing, the nutrient of plant life continues the source supplied.Mainly formulated by materials such as organic compost, inorganic mineral, soil, an agent, water-loss reducer, slow-release fertilizers.And the conventional method that living matrix is this area is planted in preparation, and those skilled in the art can prepare the living matrix of planting of variety classes and different proportionings as required.Used material also all can commercially availablely obtain.
Through method of the present invention, cement mortar anchor spray side slope is afforested, can prevent weathering that the cement sand bed long term exposure produces in air, peel off; Strengthen the slope project protection effect, guarantee domatic long-time stability and safety, simultaneously; System is led, retained to this method through setting up domatic surface flow and planting layer interflow row; Solved the domatic artificial planting layer of cement anchor spray and suffered phenomenons such as rainfall erosion, integral slipping come off, guaranteed the stable of planting layer, for slope vegetation ecology provides stability fundamental; Reach engineering measure and combine, the target that engineering safety and natural landscape are coordinated mutually with biological control measure.
