A rainwater diversion discharge device for sponge city construction

Abstract

The invention discloses a rainwater diversion discharge device for sponge city construction, which comprises a diversion box shell, a diversion filter assembly, a sludge chamber, a water inlet pipe, a transmission box body and a drainage assembly, wherein the diversion box shell is arranged in the middle There are partitions to divide it into left and right rainwater treatment structures. A manhole cover is arranged on the upper end of the left part of the diversion box shell, a diversion filter assembly is installed under the manhole cover, and a water inlet pipe is arranged on the upper end of the right part of the diversion box shell. A transmission box is installed under the water inlet pipe, the sludge chamber is set at the lower end of the right part of the splitter box shell, and the drainage assembly is set at the right side of the splitter box shell, communicates with the right side box wall, and is relatively located in the sewage Above the mudroom.

Description

technical field [0001] The invention relates to the technical field of urban rainwater discharge, in particular to a rainwater diversion discharge device for sponge city construction. Background technique [0002] Sponge city refers to a city that can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural disasters. When it rains, it absorbs, stores, infiltrates, and purifies water. use. To maximize the accumulation, infiltration and purification of rainwater in urban areas, and to promote the utilization of rainwater resources and the protection of the ecological environment. In the process of sponge city construction, coordinate water supply, drainage and other water recycling links to maximize the accumulation, infiltration and purification of rainwater in urban areas, and promote the utilization of rainwater resources and ecological environment protection. [0003] General urban rainwater drainage has failed to solve t...

AI Technical Summary

Problems solved by technology

[0003] General urban rainwater drainage has failed to solve the problem of rainwater counterflow well. Water wells often have backflow problems, resulting in not only ineffective drainage of road area water, but even traffic accidents caused by rainwater flowing out of wells, and drainage pipes often Blockage occurs, it is difficult to clean up, time-consuming and labor-intensive, the discharged rainwater is relatively turbid, mixed with stones, branches and other debris, cannot fully purify the rainwater, and greatly wastes fresh water resources
