Abstract

A flood prevention structure for sponge city construction comprises a retaining wall structural body, an adjusting culvert and a buffer wetland. A wood plug is arranged in the adjusting culvert, one side of the adjusting culvert is connected with one end of a first drainage channel, the other end of the first drainage channel is connected with the buffer wetland, the other side of the adjusting culvert is connected with one end of a second drainage channel, and the other end of the second drainage channel is arranged in the retaining wall structural body. The upper portion of one side, away from the first drainage channel, of the buffer wetland is provided with a water inlet channel, and the buffer wetland is internally provided with an adsorption layer, a filter layer, a water storage layer and a planting layer sequentially from bottom to top. Emergent aquatic plants are planted in the planting layer, and railings are arranged on two sides of a jogging track which is arranged on a ground portion between the retaining wall structural body and the buffer wetland. The flood prevention structure has advantages that internal flood discharge pressure of a dam body is effectively relieved, convenience in municipal water use is improved, rainfall flood discharge capacity of a riverway is effectively improved, and peak cutting for reservoir regulation is realized.

Description

technical field [0001] The invention relates to deep tunnel technology, in particular to a flood control structure used for sponge city construction. 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 off the exchange of materials, energy and information among the various elements of the ecosystem in the ...
