In situ planting type ecologically-transformed hard slope type revetment and transformation method

Abstract

The invention provides a hard slope type revetment formed by in situ planting type ecological transformation of a revetment. By performing slope cutting and perforating on a hard revetment, a part ofthe original hard revetment is reserved to serve as a support framework; and compared with a mode of performing ecological reconstruction on a river bank by completely dismantling the hard revetment,the engineering quantity can be reduced. Cut and crushed hard blocks can be placed in a newly-arranged ecological grid earth and stone cage to be subjected to in situ utilization and continuously playa role in stabilizing a side slope, thereby reducing the cost and reducing the engineering waste. When the hard slope type revetment is perforated, non-perforated areas near holes form a hard latticeframe mesh, and the hard lattice frame mesh and the ecological grid earth and stone cage structure placed in the lattice frame form a whole, and can together provide strength; and furthermore, the grid earth and stone cage structure has the properties of scouring resistance, corrosion resistance, wear resistance, high strength, high adaptability to foundation deformation, and the like, and can ensure the overall stability of the transformed bank slope.

Description

technical field [0001] The invention belongs to the field of river ecological restoration and reconstruction engineering, relates to the ecological transformation technology of hard slope revetment, and specifically designs a method and system for in-situ vegetation ecological transformation of hard slope revetment. Background technique [0002] Slope revetment is a kind of revetment engineering, its function is to protect the embankment of rivers, lakes and seas from the invasion and erosion of water current, wind wave and sea tide. For a long time in the past, when people built river revetments, they only considered the safety and durability of revetment works, so most of the rivers chose hard revetments. This structure not only protects embankments, but also blocks water and land ecology. The interconnection of the system has seriously damaged the ecological health function of the river, and even affected the stability of the entire ecosystem, which is not conducive to th...

Problems solved by technology

[0006] The present invention solves the technical problems that the hard bank revetment transformation method in the prior art has a large amount of engineering, relatively high funds required or difficult to solve the barrier of the bank revetment itself, and the added matrix introduced is easy to affect the survival of animals and plants. Furthermore, it provides a small amount of engineering and cost-saving method for in-situ planting ecological transformation of hard slope revetment
