Purification type rainwater regulation and storage system special for green sponge and construction process thereof

Abstract

The invention discloses a purification type rainwater regulation and storage system special for a green sponge. The purification type rainwater regulation and storage system special for the green sponge comprises a pretreatment system and a water storage system, a concrete layer is arranged in an inner cavity of the pretreatment system, a waterproof layer is arranged in the interior of the concrete layer, a pretreatment pool is arranged in an inner cavity of the concrete layer, and a connecting pipe is arranged on one side of the pretreatment tank in a penetrating manner. An existing buildingconstruction means is combined, the purification type rainwater regulation and storage system special for the green sponge and the construction technology of the purification type rainwater regulationand storage system are designed, a water storage and drainage system can achieve preliminary filtration of rainwater, external large garbage and sundries are prevented from entering an urban sewer line network, so that the occurrence of blockage is fundamentally avoided; and meanwhile, the rainwater in the inner cavity of the pretreatment pool can be discharged into the inner cavity of a water storage tank to be accumulated after secondary filtering is carried out on the rainwater by utilizing the cooperation of a water pump, a guide pipe, a drainage pipe and a filter pipe structure through aconnecting pipe.

Description

technical field [0001] The invention relates to the technical field of sponge cities, in particular to a purification-type rainwater regulation and storage system dedicated to green sponges and a construction process thereof. Background technique [0002] Sponge city is a new generation of urban rain and flood management concept, which 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 rain. It can also be called a water elastic city. Water absorption, water storage, water seepage, water purification, release and use the stored water when needed, and realize the free migration of rainwater in the city. Under the new situation, sponge city is to promote the construction of green buildings, the development of low-carbon cities, and smart cities The innovative performance formed is an organic combination of modern green new technologies and various factors such as society, environme...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a green sponge-specific purification type rainwater storage system and its construction technology, which has the advantages of good filtering effect, not easy to block, easy construction and active drainage, and solves the problem of the existing sponge city rainwater storage facilities The structure is single, and the impurities on the street are often carried by the rainwater into the regulation and storage system. During the long-term use, most of the existing regulation and storage facilities do not have a filtering structure, and the main body of the structure is very prone to blockage. Sanitation workers often clean up, causing a huge burden on sanitation workers, and most of the existing storage facilities do not have the function of active drainage, and the city's ability to resist floods is weak.
