Ecological wetland bank protection structure based on river and lake topography remolding and construction method of ecological wetland bank protection structure

Abstract

The invention discloses an ecological wetland bank protection structure based on river and lake topography remolding. The ecological wetland bank protection structure comprises a current old wall structure located at the revetment, a riprap protection slope, a waterborne platform, wave attenuation landscape ecological plants, a submerged dam, a filling soil platform and biocenoses, wherein the wall body of the current old wall structure is removed at least below the perennial average constant water level; the riprap protection slope is built on the wall back slope surface of the current old wall structure; the waterborne platform is built at the wall back slope top of the current old wall structure and located on the rear side of the riprap protection slope; the wave attenuation landscapeecological plants are planted at the outer edge of the waterborne platform; the submerged dam is built on the river and lake beach land in front of the current old wall structure; the filling soil platform is constructed on the river and lake beach land and located between the current old wall structure and the submerged dam; and the biocenoses are constructed on the filling soil platform. The invention further discloses a construction method of the ecological wetland bank protection structure based on river and lake topography remolding. The ecological wetland bank protection structure basedon river and lake topography remolding has good ecological restoration effects and is beneficial to river and lake shorelines.

Description

technical field [0001] The invention relates to the technical field of water conservancy bank revetment structures, in particular to an ecological wetland bank revetment structure based on river and lake topography remodeling and a construction method thereof. Background technique [0002] With the gradual deepening of the concept of ecological civilization, it is increasingly necessary to promote the comprehensive management of river and lake water environments, strengthen the ecological restoration of river and lake water, and systematically improve the health of river and lake water ecosystems. [0003] Constructing wetlands around rivers and lakes is an important means of restoring aquatic ecosystems. In the management of rivers and lakes, by retaining and building some peripheral wetlands and building biological communities, the functions of wetland regulation and storage, water conservation, pollutant degradation and buffering can be realized. These wetlands will also...

Problems solved by technology

[0004] However, in actual engineering, on the one hand, the water depth, large waves, and rapid currents in front of the traditional vertical revetment wall for flood control in rivers and lakes make it difficult for the plant communities in the peripheral wetland system to survive; on the other hand, the flood wall blocks the material and energy between land and water Exchange, thus affecting the construction effect of the water ecological environment, failing to meet the requirements of ecological restoration of rivers and lakes
