Water seepage and flood drainage system based on sponge city

Abstract

The invention relates to a water seepage and flood drainage system based on a sponge city, which includes a water storage tank arranged under the road inspection well, the water inlet on the top surface of the water storage tank and the water leakage port on the bottom surface of the road inspection well are connected through a communication cavity, and a water tank is installed in the water leakage port Coarse filter screen, fine filter screen is installed in the water inlet; water pump is installed at the bottom of the water storage tank, and the water outlet of the water pump is connected with the landscape lake in the city park through the water pipe, and the ground layer surrounding the landscape lake is Suspended layer, and the suspended layer is connected with the landscape lake, the edge of the supporting plate close to the landscape lake is fixedly connected with the supporting plate for supporting the planting layer and the water storage layer, and the supporting column is supported under the supporting plate, and the planting layer Landscape plants are planted on the top, and vertical permeable holes are distributed on the supporting plate. The invention can effectively store rainwater, purify and reutilize the rainwater, and provide more water resources for urban parks.

Description

technical field [0001] The invention relates to the technical field of drainage engineering, in particular to a seepage and flood drainage system based on a sponge city. Background technique [0002] At present, with the advancement of my country's urbanization process, the overall scale of the city continues to expand, and the hardening of the urban ground has intensified, resulting in an increase in the coefficient of rainwater runoff. In case of heavy rain, water is easy to accumulate on the road surface, and in severe cases, it is easy to cause paralysis of urban road traffic and casualties. Sponge city means that the city can be like a sponge and has good elasticity in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". Due to the frequent occurrence of extreme weather in our country, waterlogging is common in many cities after heavy rainfall. The concept of sponge city has attracted mo...
