River embankment structure for sponge city construction

Abstract

The invention discloses a river embankment structure, in particular discloses a river embankment structure used for sponge city construction, and belongs to the technical fields of urban landscape and river channel improvement architecture. Provide a river embankment structure for sponge city construction that can effectively absorb street flow during flood periods of heavy rainfall, and can seep out water flow during periods of drought and little rain. The river bank embankment structure includes a concrete or masonry masonry dam, and the river embankment structure also includes a floc backfill system, and a drainage system is arranged in the middle and lower part of the concrete or masonry masonry dam along the vertical direction, A reverse permeable system is arranged on the middle and upper part of the concrete or masonry dam, and the flocculation backfill system is arranged on the inner side of the concrete or masonry dam, and the drainage system and the reverse permeable system The input ends are respectively communicated with the flocculation backfill 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 ...

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.
