River embankment structure for sponge city construction

Abstract

The invention discloses a river embankment structure, particularly discloses a river embankment structure for sponge city construction, and belongs to the technical field of cityscape and channel improvement buildings. The river embankment structure for sponge city construction can effectively absorb street runoff in a flood period with heavy rainfall, and water flow can seep out in a draught period with less rainfall. The river embankment structure comprises a concrete or masonry dike and a flocculent backfilling system. A drain system is arranged on the lower middle portion of the concrete or masonry dike in the vertical direction. A reverse water permeation system is arranged on the upper middle portion of the concrete or masonry dike. The flocculent backfilling system is arranged on the inner side of the concrete or masonry dike. The input end of the drain system and the input end of the reverse water permeation system are communicated with the flocculent backfilling system.

Description

technical field [0001] The invention relates to a river embankment structure, in particular to a river embankment structure used for the construction of a sponge city, and belongs to the technical fields of urban landscape and river regulation buildings. Background technique [0002] Traditional urban construction ideas emphasize hardening the water surface as much as possible, isolating water flow, and preventing seepage, including road surfaces, river channels, especially the bottom plates of river channels, and retaining walls on both banks. As a result, runoff, that is, the flow of surface water, has been greatly increased, and the water tolerance and elasticity of cities, especially along river channels, have been reduced. What's more serious is that the river bed and slopes were often closed and solidified in the past river course improvement, which made it impossible for the water flow to communicate with the outside world when flowing through the urban area, cutting ...

AI Technical Summary

Problems solved by technology

This method can make the precipitation infiltrate and discharge into the river through the bank slope soil, but the water flow in the river with poor water quality cannot make full use of the ecological purification function of the soil on both sides of the river.
