Combined ecological revetment and construction method thereof

Abstract

Provided is a combined ecological revetment and a construction method thereof. The combined ecological revetment comprises an osmotic adsorption filter layer, a wooden pile protecting foot, a stone cage retaining wall, a bottom mud ecological bag layer and a vegetation layer, wherein the osmotic adsorption filter layer is arranged at the junction of a river bank slope and a river bed, and comprises two layers of water-permeable concrete layers and an adsorption filter layer, and the bottom of the wood pile protecting foot is embedded in the part, adjacent to the outer edge of a stair at the bottom layer of the osmotic adsorption filter layer, of the river bed; the stone cage retaining wall comprises a binge net cage and a support, the bottom mud ecological bag layer is composed of a plurality of bottom ecological bags, and the vegetation layer is composed of a soil layer and a vegetation net; the construction method of the combined ecological revetment comprises the following steps: laying the osmotic adsorption filter layer, stone cage retaining wall and vegetation layer sequentially on the stair-type slope surface of the slope surface of the river bank, and embedding the wood pile protecting foot at the foot of the slope. The combined ecological revetment has the advantages that: full exchange of a water body is achieved, N, P, heavy metals and other pollutants in the water body can be adsorbed effectively, meanwhile, the own strong anti-scour ability of the combined ecological revetment can be ensured, and good durability and applicability are achieved.

Description

technical field [0001] The invention relates to a combined ecological revetment and a construction method thereof. Background technique [0002] Ecological revetment refers to a form of revetment that uses plants or a combination of plants and geotechnical materials to protect the slope of the river. It is an artificial revetment with the nature of a natural river bank. , adjust the water level, purify the river and other functions, and form a harmonious river landscape with the surrounding environment. On the whole, ecological revetment is an improvement of traditional revetment. It is the product of the development of river control engineering to a relatively advanced stage. It is the need of modern people to live in harmony with nature. It is the inevitable result of the development and progress of revetment engineering technology. [0003] On the other hand, a large amount of silt deposited on the bottom of the river seriously affects the functions of flood control, nav...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the problems existing in the traditional bank revetment technology and the weak erosion resistance or low water purification efficiency of some current ecological bank revetment technologies, the present invention proposes a combined ecological bank revetment and its construction method. The space for habitat and reproduction can ensure sufficient water exchange between the river bank and the river, and can effectively absorb pollutants such as N, P, and heavy metals in the water body.
