Description
Technical field
The utility model relates to a kind of rock matter high gradient slope ecological revetment and uses plant-growth carpet, is mainly used in the revegetation of rock matter high gradient slope, the quick planting that also can be used for barren slight slope or abandoned mine side slope with reclaim, belong to the environmental geotechnical field.
Background technology
Along with the Large scale construction of national freeway net and the large-scale development in mine, the bare side slopings of a large amount of excavations have produced water and soil conservation, the ecological balance and environmental protection and to have had a strong impact on, and have caused heavy losses.Slope ecological destruction not only can directly cause water and soil loss and destroy engineering construction itself, and can impact and threaten the people life property safety through environment and safe disaster.Geological disasters such as new excavation slope departs from even away from ecological balance state, under environment and engineering factor influence, side slope slope body very easily brings out and caves in, landslide cause enormous economic loss and casualties.Therefore, must in time reasonably protect behind the slope excavating, to reduce the generation of environment and safe disaster to it.The ecological revetment mode then is the optimal selection that solves slope ecological and safety problem.
Usually, soil property preferably side slope can directly pass through the grass planting ecology recovering.And characteristics such as high steep rock mass slope has that the gradient is steep, soil property difference and difficulty of construction are big, directly grass planting then is difficult to into alively, and therefore, its restoration of the ecosystem is the engineering roadblock that needs to be resolved hurrily.Therefore, the slope vegetation protection Study on Technology of the side slope of high steep bare rock or soil property difference has become current environment Geotechnical Engineering field research and development focus and emphasis.At present; To the vegetation on slope problem; Many scholars have carried out relevant research with engineers and technicians; Developed thick-layer base material grass planting, the hydraulic pressure technology such as grass planting of gushing of sowing grass seeds by duster, but these methods or, or can not be widely used in the vegetation on slope of high steep bare rock or soil property difference because of shortcomings such as protection effect differences because of difficulty of construction is big.And the emerging living band bank protection of planting mainly applies to soft gentle slope, and its structure function can not satisfy the restoration of the ecosystem of high steep rock mass slope.Like: traditional non-woven fabric adhesive lawn plant-growth carpet or plant and give birth to band, tensile strength is low, and plant growth medium is prone to landing, only is applicable to laying lawn, gentle slope; Vegetation bag dress mound block method, construction is complicated, cost is high, and has the resistance to overturning potential safety hazard.These plant living band, plant-growth carpet or the decision of vegetation bag self structure defective, and it is not suitable for the ecological protection engineering of high steep rock mass slope.
Summary of the invention
To the problem of above-mentioned existence, the purpose of the utility model is to provide a kind of rock matter high gradient slope ecological revetment to use plant-growth carpet.To achieve these goals, the technical solution of the utility model is:
A kind of rock matter high gradient slope ecological revetment with plant-growth carpet by conservation layer, go up bearing layer, seed liquor slurry layer, go up integument, hypothallus, middle integument, integument and following bearing layer constitute down; Middle integument is wavy; The below of integument in the middle of following integument is positioned at, following bearing layer are positioned at the below of integument down, and the trough of middle integument is fixedly connected with following integument, following bearing layer; The top of integument in the middle of last integument is positioned at; Last bearing layer is positioned at the top of integument, and conservation layer is positioned at the top of bearing layer, and the crest of middle integument is fixedly connected with last integument, last bearing layer, conservation layer; Seed liquor slurry layer is between last bearing layer and last integument, and hypothallus is filled between integument and the following integument by integument separation in the middle of wavy.
Described conservation layer is a kind of in nonwoven or the degradable paper.
It is the plastic wire of 3cm～5cm that described upward bearing layer adopts mesh.
Described seed liquor slurry layer is made up of seed, paper pulp, water-loss reducer, binding agent, compound fertilizer and agricultural chemicals.
The nonwoven that described upward integument, middle integument and following integument are thickness 1.5mm～3.5mm.
Described hypothallus is made up of planting soil, river embankment mud, water-loss reducer, slow release fertilizer and agricultural chemicals.
It is the plastic wire of 1cm～3cm that described bearing layer down adopts mesh.
Owing to adopted above technical scheme; A kind of rock matter high gradient slope ecological revetment of the utility model can be realized the revegetation of rock matter high gradient slope with plant-growth carpet; And the quick planting of the soil-slope of soil depletion or abandoned mine side slope with reclaim, have following technical characterstic and advantage:
1. plant-growth carpet adopts the middle integument of undaform that hypothallus is divided into several zonules, and when being used for the high gradient slope ecological revetment, matrix can integument slippage under the action of gravity lower edge, has guaranteed the stability of matrix.
2. compare with vegetation bag, this plant-growth carpet is the blanket shape, has good whole property, is tiled in domaticly, has avoided vegetation bag to pile up issuable whole unstability.
3. plant growth medium is wrapped in the plant-growth carpet, even the serious phenomenon of washing away can not appear in rainstorm weather yet, corrosion resistance is extremely strong.
4. be integument with the nonwoven, both had good permeable, ventilative, light transmission, have good water conservation again, protect fertile, the anti-effect of shining, the penetrable nonwoven of root system of plant, the smooth growth of assurance plant.
5. be the main plant growth substrate with river embankment mud, draw materials conveniently that cost is low, has realized twice laid.The nitrogen, phosphorus, potassium and the organic principle that enrich in the mud can be plant growing enough nutrient components are provided.
6. this plant-growth carpet is simple in structure, speed of production is fast, and generative process can be in indoor completion, and process of deployment is simple, rapid, does not receive weather influence, can realize on-the-spot rapid construction.
