Urban small watershed watercourse quick storage and slow release sponge embankment structure
The invention discloses an urban small watershed watercourse quick storage and slow release sponge embankment structure. The urban small watershed watercourse quick storage and slow release sponge embankment structure comprises an embankment wall composed of an embankment bottom plate and an embankment panel, wherein the interior of the embankment wall is sequentially filled with a coarse sand layer and a gravel layer in vibrating compaction mode, a plurality of communication pipelines are arranged in the embankment bottom plate at intervals in penetration mode, a small pore reversed filter bag is arranged on the embankment bottom plate, a plurality of flood discharge pipelines are arranged in the middle of the embankment panel at intervals in penetration mode, a macro pore reversed filter bag is arranged in the middle of the embankment panel, a gravel and coarse sand cushion layer is arranged below the embankment bottom plate, and dry laid stone guard feet are laid on the outer side of the gravel and coarse sand cushion layer and the outer side of the embankment bottom plate. The urban small watershed watercourse quick storage and slow release sponge embankment structure enables the embankment wall to have a water storage function by being filled with padding high in void ratio, and exchanges water with a watercourse water body through the communication pipelines so as to achieve a water body storage release, and simultaneously due to the fact that the flood discharge pipelines can massively and rapidly guide flood above the warning water level into the embankment wall and store the flood, a flood peak reduction purpose is achieved, the water stored in the embankment wall can slowly seep into a watercourse through the communication pipelines, and water replenishing for the watercourse is achieved.
