Urban road rainwater storage and drainage system and urban road rainwater storage and drainage method

Abstract

The invention discloses an urban road rainwater storage and drainage system. The urban road rainwater storage and drainage system is characterized by comprising a rainwater pipeline drainage system (1), a sewage pipeline drainage system (2), one or more first rain storage system (3) and a later rain storage system (4); the rainwater pipeline drainage system (1) and the sewage pipeline drainage system (2) are arranged along a road; each first rain storage system (3) comprises a flow division well (30) used for dividing first rain, is communicated with the rainwater pipeline drainage system (1) through the corresponding flow division well (30) and is communicated with the sewage pipeline drainage system (2) through a first rain return pipeline (3a); the later rain storage system (4) comprises a later rain collection well (40) and is communicated with the rainwater pipeline drainage system (1) through the later rain collection well; the later rain collection well is positioned at a downstream position of one flow division well (30) and is adjacent to one flow division well (30), and a downstream position of the later rain storage system (4) is communicated with the rainwater pipeline drainage system (1) through a later rain return pipeline (4a).

Description

technical field [0001] The invention relates to the technical fields of urban drainage and environmental protection, in particular to a rainwater storage and drainage system and method for urban roads. Background technique [0002] At present, the rainwater utilization technology of urban roads has been gradually developed. In most cases, the footpaths are made into permeable pavements; the low-lying shallow water infiltration areas or infiltration channels built on the separation belts or green belts on both sides of the road; the infiltration pipes buried along the road Ditch; infiltration wells and infiltration ponds distributed along the road. The advantage of these technologies is that they can reduce initial rainwater in situ, and allow rainwater to infiltrate into the ground, replenishing groundwater and rehydrating plants. But the problem is that for the infiltration of rainwater from the surface, the purification function of the soil can be used, but it is difficul...

AI Technical Summary

Problems solved by technology

In general, the infiltration of rainwater has many problems of declining use efficiency and difficult management, while the use of rainwater storage has difficulties in the initial rainwater abandonment and outlet and it is difficult to find land for centralized water storage.
