Sponge city seepage and drainage structure and water circulation system thereof

Abstract

The invention discloses a sponge city seepage and drainage structure and a water circulation system thereof, relates to a city seepage and drainage system, and aims to solve the problem that a pipeline of a water collecting port is easy to block in the prior art. The technical scheme is characterized in that the sponge city seepage and drainage structure comprises a reservoir, a water collecting ditch for rainwater to flow to the reservoir and at least one drainage ditch for rainwater to flow to the water collecting ditch, wherein the water collecting ditch and the drainage ditch are laid on the ground, and filtering assemblies are detachably arranged in the water collecting ditch and the drainage ditch; rainwater enters the drainage ditch and the water collecting ditch, the rainwater entering the drainage ditch enters the water collecting ditch again, and finally is discharged into the reservoir along the water collecting ditch, and impurities in the water collecting ditch and the drainage ditch are filtered by utilizing the filtering assemblies; and when the impurities are filtered more, the filtering assemblies are detached from the water collecting ditch and the drainage ditch, and the impurities are taken out, so that the possibility that the impurities block the drainage ditch and the water collecting ditch, and consequently water cannot be drained to the reservoir can be reduced, and the possibility that water storage of the reservoir is influenced can be reduced.

Description

technical field

[0001] The invention relates to an urban seepage and drainage system, more specifically, it relates to a sponge city seepage and drainage structure and a water circulation system thereof. Background technique

[0002] Sponge city is a new generation of urban stormwater management concept. It 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".

[0003] The Chinese patent with the authorized publication number CN206844268U discloses a microcirculation device for the construction of smart sponge cities. The microcirculation device includes: a rainwater collection and storage module connected to the residential area pipe network, which is used to collect and filter rainwater for cleaning use water, and store or discharge rainwater and the cleaning water; the rainwater recycling module is used to extract the cleanin...
