Infiltration and drainage structure of sponge city and water circulation system of sponge city

Abstract

The invention relates to the technical field of water conservancy engineering, in particular to a sponge city infiltration and drainage structure and a sponge city water circulation system, including a sedimentation sewage collection tank, a filter overflow tank, a water storage tank and a transpiration drainage tank, the sedimentation sewage collection tank and the filter overflow tank. , The water storage tank and the transpiration drainage tank are sequentially connected through pipes, the upper surface of the transpiration drainage tank is open, and the transpiration water-absorbing cotton is fixedly installed inside the opening, and the upper surface of the transpiring water-absorbing cotton is arranged in a raised position. There are transpiration corrugated strips; the present invention can collect and filter urban precipitation such as rainwater and store it in the interior of the water storage tank by setting the sedimentation sewage collecting cylinder and the filtering overflowing cylinder, so as to improve the utilization rate of rainwater when the rainfall is low. The different water circulation systems are connected to each other, so that the rainwater can be evenly distributed in the seepage and drainage structure, and the water storage capacity in the storage tanks of all the water circulation systems is ensured to be close, so that all the storage tanks are fully utilized.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a sponge city seepage and drainage structure and a sponge city water circulation system. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It means that cities can be like sponges and have good flexibility in adapting to environmental changes and responding to natural disasters caused by rainwater. Starting from ecosystem services, through cross-scale construction Water ecological infrastructure, combined with a variety of specific technologies to build water ecological infrastructure, is the core of the sponge city. [0003] The seepage and drainage structure and water circulation system of many medium and large cities in China are not perfect enough to fully collect and utilize precipitation during low precipitation. Therefore, it is not possible to quickly empty the accumulated water while increasing th...

Problems solved by technology

[0003] The seepage and drainage structures and water circulation systems of many large and medium-sized cities in China are not perfect enough to fully collect and utilize precipitation during low precipitation, and cannot quickly prepare for circulation before the arrival of high rainfall, and cannot quickly transpirate accumulated water to In the air, it is impossible to quickly drain the accumulated water while increasing the ambient humidity to meet the heavy precipitation in the future
