Ecology-friendly city river channel retaining wall system

Abstract

The invention relates to an ecology-friendly city river channel retaining wall system which is arranged on a side slope of a river channel (9) and comprises a bottom layer retaining wall (1) and an upper layer retaining wall (2). The bottom layer retaining wall (1) is arranged below a normal water level (5); the upper layer retaining wall (2) is arranged on the upper portion of the bottom layer retaining wall (1); the top of the upper layer retaining wall (2) is higher than a flood level (6); the gradient of the bottom layer retaining wall (1) is larger than that of the upper layer retaining wall (2); an upwarping part (3) which upwarps towards the center of the river channel is arranged on the top of the bottom layer retaining wall (1); and a connecting groove (4) is formed between the upwarping part (3) and the upper layer retaining wall (2). Compared with the prior art, according to the ecology-friendly city river channel retaining wall system, the flood detention water quantity in the flood season of the river channel can be effectively increased, and an overwater ecological corridor and an underwater ecological corridor of the river channel communicate in a network shape; the necessary material foundation guarantee is provided for biological diversity; and the ecological function of the river channel is greatly enriched, the ecological environment effect of a city is effectively improved, and the diverse landscape effect of the city river channel is enriched.

Description

technical field [0001] The invention relates to a barge, in particular to an eco-friendly urban river barge system. Background technique [0002] In addition to the general water system communication and landscape sightseeing functions, urban rivers often have the water conservancy function requirements of urban drainage and flood discharge during flood seasons. Therefore, the revetments of urban rivers are often in the form of vertical hard revetments, in order to facilitate the smooth and safe drainage and flood discharge during the flood season. [0003] This kind of revetment has the following problems: the vertical revetment is not conducive to the river carrying more flood during the flood season, and it acts as a sponge for flood detention and diversion. Moreover, such a simple treatment is very weak to the ecological function of the river channel, which is an important carrier of the urban ecological environment. The hardened ridges cannot allow animals and plants t...

Moreover, such a simple treatment is very weak for the ecological function of the river channel, an important carrier of the urban ecological environment, and the hardened ridges cannot allow animals and plants to survive at all, let alone biodiversity and biological corridors.
