Description

Quick assembly disassembly's double-deck ecological flood control barricade

Technical Field

The utility model relates to the technical field of ecological flood control, in particular to a quick-detachable double-layer ecological flood control retaining wall.

Background

Flood disasters are one of the most serious natural disasters that endanger human production and life. In recent years, the climate changes year by year, which causes the occurrence of flood disasters and the loss caused by flood disasters to become more serious. Flood control barricade has made positive contribution in effectively resisting the flood infringement aspect, and flood control barricade is mainly used for two kinds: firstly, permanent retaining wall, secondly the flood control baffle can be dismantled to emergent formula. The flood control retaining wall type commonly used in China is a gravity type flood control retaining wall formed by stacking materials such as masonry stones, the flood control retaining wall is generally applied to suburb environments such as river banks, the functions of flood running, drainage, irrigation, navigation, water supply and the like of rivers and lakes are generally considered, the relation between the biological community composition of rivers and the surrounding environment of the rivers is reduced, and the natural function of the rivers is considered less. With the development of ecological flood control, the flood control retaining wall not only needs to meet the flood control function, but also needs to meet the ecological natural requirements of landscape, hydrophilicity and the like. Factors such as flood control, view and admire and the current of flood are taken into comprehensive consideration to the removable flood control barricade, and its advantage can be assembled according to the flood condition comparatively in a flexible way, and is less to the influence of river course surrounding environment.
