Rain water system for building districts of sponge cities and construction method of rain water system

Abstract

The invention discloses a rain water system for building districts of sponge cities. The rain water system is characterized by comprising a sedimentation pond, a distribution well, a treatment pond and overflow wells, wherein an environment-friendly rain water opening is formed in a position above the sedimentation pond, the sedimentation pond is connected with the distribution well through a water inlet pipe, a water inlet valve is arranged on the water inlet pipe, at least four distribution pipes are arranged on the left end surface of the distribution well, the distribution well is connected with the treatment pond through the distribution pipes, and the treatment pond is connected with the overflow wells through overflow pipes. A construction method of the rain water system comprises the following steps: (1) performing construction preparation; (2) excavating foundation pits; (3) performing foundation treatment; (4) building the sedimentation pond and the distribution well; (5) building the treatment pond and the overflow wells; (6) laying pipelines; and (7) performing ground treatment. The rain water system disclosed by the invention is simple in structure and high in practicability, and is used for collecting and treating rain water on the ground of building districts, so that the phenomenon of water accumulation on the ground of the districts is effectively avoided; and besides, rain water is collected, so that waste of water resources can be reduced.

Description

technical field [0001] The invention relates to a rainwater system used in a sponge city building area and a construction method thereof. Background technique [0002] Sponge city is a new generation of urban stormwater management concept, which means that the city has good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city", an international general term Built for "Low Impact Development Stormwater Systems". Sponge city can absorb, store, infiltrate, and purify water when it rains, and "release" the stored water and use it when needed. Through source reduction, process control, system governance, etc., buildings and communities, roads and squares can be integrated. , parks, green spaces, and water systems have the functions of absorbing, storing, and slowing release of rainwater, effectively controlling rainwater runoff, no water accumulation in light rain, no waterlogging in ...

AI Technical Summary

Problems solved by technology

In recent years, sunken green spaces, infiltration ponds, wet ponds, etc. have begun to attract attention and have been rapidly constructed. However, due to the relatively single filler, although the infiltration of surface rainwater has been accelerated to a certain extent, it is difficult to effectively store it, and the rainwater has not been purified. , the rainwater is directly discharged into the river without treatment, which has a certain pollution effect on the river.
