Regulation and storage structure for sponge city road construction

Abstract

The invention relates to a regulation and storage structure for sponge city road construction. The regulation and storage structure for sponge city road construction is arranged on the two sides of aroad, and comprises a rainwater well and a multifunctional overflow water storage unit arranged on one side of the rainwater well, wherein a slow release device and a sewage draining assembly are arranged on the bottom part of the multifunctional overflow water storage unit; the bottom part of the slow release device is connected to the rainwater well through a slow release water outlet pipe; a sewage draining pipe is connected to the bottom part of the sewage draining assembly; and an overflow port is formed between the upper part of the multifunctional overflow water storage unit and the rainwater well. Compared with the prior art, the regulation and storage structure for sponge city road construction provided by the invention can be beneficial to effectively reducing a city rainwater drainage peak value, alleviating the drainage pressure of an existing drainage pipe network, reducing the investment cost of the drainage pipe network, particularly effectively reducing the pollution brought by initial rainfall-runoff and improving the river water quality, and has favorable ecological benefits and social benefits.

Description

technical field [0001] The invention belongs to the field of urban construction, and in particular relates to a regulating and storing structure for road construction in a sponge city. Background technique [0002] Sponge city construction is an important concept change in the way of urban development, an important part of the construction of ecological civilization, and a manifestation of the mainstream values ​​of ecological civilization, among which "reducing emissions at the source" is the top priority. In actual engineering practice, the "two rates" of "source emission reduction" are: "the total annual runoff control rate" and "annual runoff pollution removal rate" are the most important indicators. [0003] With the continuous advancement of the sponge city construction projects in various pilot cities, the industry has become more and more clear about the relationship between the two rates in the construction of sponge cities: "the total annual runoff control rate" is...

AI Technical Summary

Problems solved by technology

However, this structure cannot both regulate and store rainwater and purify rainwater, and cannot effectively reduce the peak value of urban rainwater discharge, reduce the drainage pressure of the existing drainage pipe network, and have limited impact on improving river water quality.
