In-situ vegetation type ecological transformation structure and method for hard sloping revetment

Abstract

The invention provides an in-situ vegetation type ecological transformation structure and method for a hard sloping revetment. By performing cutting and perforating on a slope surface of the hard revetment, part of the prior hard revetment is reserved to serve as a supporting framework, and compared with the practice that the hard revetment is completely dismounted for performing ecological reconstruction on the revetment, the engineering quantity can be reduced. Hard fragments obtained after cutting and crushing can be arranged in newly-laid ecological grid earth and rockfill cages so as to achieve in-situ utilization, the fragments continue to play a role in the effect of slope stabilizing, the cost is saved, and engineering waste is reduced. When the hard sloping revetment is perforated, non-perforated areas located nearby holes form a hard lattice framework net, the hard lattice framework net and the ecological grid earth and rockfill cage structures arranged in grids form an integrated body, the strength can be provided jointly, meanwhile, the grid earth and rockfill cage structures have the performance of scouring resistance, corrosion resistance, abrasion resistance, high strength, high foundation deformation adaptability and the like, and the overall stability of a modified revetment slope can be guaranteed.

Description

technical field [0001] The invention belongs to the field of river ecological restoration and reconstruction engineering, relates to a hard slope revetment ecological transformation technology, and specifically relates to an in-situ planting ecological transformation structure and method for a 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 the...

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
