Description
Technical field
The present invention relates to a kind of side slope protective screen, particularly a kind of composite layered structure side slope protective screen.
Background technology
The mankind are to the exploitation behavior of the resources such as ore, coal, oil, water, constructional materials and when carrying out the engineering constructions such as railway, highway, water conservancy, mine, tunnel, building, to construction behaviors such as the excavation landfills of ground, create a large amount of exposed anxious precipitous rock slopes, result in original environment and ecosystem serious unbalance.Further, these activities of the mankind usually cause some geological disaster, as: surface settlement, landslide, avalanche, soil erosion etc.Therefore, side slope protective screen is adopted effectively can to avoid the generation of the phenomenons such as landslide, avalanche and soil erosion.
But the side slope protective screen of prior art usually adopts flexible wire ropes to weave and forms, long term exposure in atmosphere, after exposing to the weather and drenching with rain, wire rope be there will be the phenomenons such as fracture by corrosion, and the soil environment of metal object sedimentation to massif has tremendous influence, massif soil self is also difficult to grow vegetation again, and this kind of method is effected a permanent cure and do not taken stopgap measures; Adopt if simple and can make protective screening by settled material, if if although the gap of netting can prevent the native stone of bulk from dropping comparatively greatly, the native stone of smaller piece cannot be prevented, effectively can prevent native stone from dropping if the gap of netting is less, but cannot ensure that vegetation has sufficient space to grow.
