River ecological revetment and construction method thereof

Abstract

The invention relates to a river ecological revetment and a construction method of the river ecological revetment. The river ecological revetment comprises a permeable adsorption filter layer, timberpile protection feet, a gabion retaining wall, a sediment ecological bag layer and a vegetation layer. The permeable adsorption filter layer is arranged at the junction of a river bank slope and a river bed, and the permeable adsorption filter layer comprises two permeable concrete layers and an adsorption filter layer. The bottom ends of the timber pile protection feet are embedded into the portion, adjacent to the outer edge of a bottom layer step of the permeable absorption filter layer, of the river bed. The gabion retaining wall comprises a gabion net cage and supports. The bottom sediment ecological bag layer is composed of multiple bottom layer ecological bags. The vegetation layer is composed of a soil layer and a vegetation net. The construction method comprises the following steps that the permeable adsorption filter layer, the gabion retaining wall and the vegetation layer are sequentially laid on the stepped slope of the river bank slope, and the timber pile protection feetare embedded into the slope toe position. The river ecological revetment and the construction method have the beneficial effects of ensuring the full exchange of water bodies, effectively adsorbing pollutants such as N, P and heavy metals in the water bodies, simultaneously ensuring the high anti-scouring capability of the water bodies and having good durability and applicability.

Description

technical field [0001] The invention relates to a river channel 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...

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 river ecological bank revetment and its construction method, which can provide habitat for aquatic organisms The space for breeding 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. At the same time, the flexible structural system of the revetment ensures its strong anti-scouring ability and good durability sex and applicability
