Description

Technical Field

[0001] The utility model mainly relates to the field of sponge cities, and particularly relates to a filtering and drainage device for sponge cities. Background Art

[0002] A sponge city is a new generation of urban rainwater management concept, which means that a city can be like a sponge and has good elasticity in adapting to environmental changes and coping with natural disasters brought by rainwater, and can also be called a "water elastic city".

[0003] A city can be like a sponge and has good "elasticity" in adapting to environmental changes and coping with natural disasters. The international general term is "low impact development rainwater system construction". When it rains, it absorbs, stores, infiltrates, and purifies water. When needed, the stored water is released and utilized to realize the free migration of rainwater in the city.

[0004] Among them, a sponge city collects rainwater through a drainage structure, and the drainage device mainly conveys rainwater to the water storage position through pipelines. However, rainwater will also carry impurities into the pipelines inside the drainage device, and the impurities adhering to the inner wall of the pipelines are likely to cause a decrease in the drainage volume of the pipelines.
