A sponge city seepage structure and sponge city water circulation system

Abstract

The present invention relates to the technical field of sponge city, in particular to a sponge city seepage drainage structure and a sponge city water circulation system, which includes a rainwater well, a diversion well, a filter device and a water storage tank, and the rainwater well includes an outer well and an inner well arranged in the outer well, The top of the outer well is equipped with a rainwater grate that is flush with the ground, and the inner well is equipped with a filter hanging basket with an upward opening. The bottom of the inner well is connected with a water storage pipeline connected with a grass ditch. The cavity is connected with an overflow hole; a filter screen is arranged between the outer well and the diversion well. The method of graded drainage can achieve the purpose of quickly reducing the road surface water, and it is not easy to cause rainwater deposition, so that the drainage capacity of the urban drainage system can be effectively improved. At the same time, it increases the water storage capacity of the city and saves urban water resources. Moreover, the setting of the rainwater grate, the filter hanging basket and the filter screen can filter the rainwater and effectively remove impurities contained in the rainwater.

Description

technical field [0001] The invention relates to the technical field of sponge cities, in particular to a sponge city seepage drainage structure and a sponge city water circulation system. Background technique [0002] Sponge city is a new generation of urban stormwater management concept, which can also be called "water elastic city". The international general term is "low-impact development stormwater system construction". To build a sponge city, coordinate the use of natural ecological functions and artificial intervention functions, effectively control rainwater runoff, and realize the urban development mode of natural accumulation, natural infiltration, and natural purification, which is conducive to restoring urban water ecology, conserving water resources, and enhancing urban waterlogging prevention capabilities. Expand effective investment in public goods, improve the quality of new urbanization, and promote the harmonious development of man and nature. [0003] At ...

AI Technical Summary

Problems solved by technology

Temporary pumping and drainage is required, which affects the normal operation of the city and also causes huge economic losses

[0004] Especially in some coastal cities, especially in the case of extreme rainfall, the structure of the sponge city cannot effectively deal with the rainwater in a timely manner and is prone to waterlogging disasters
