A Sponge City Road Drainage System

Abstract

The invention discloses a sponge city road drainage system, which includes a drainage channel dug on the roadbed, an annular groove is dug under the roadbed, and the annular groove communicates with the drainage channel through a diversion groove. A first baffle is slidably connected in the annular groove, a second baffle is fixedly connected in the annular groove, and the first baffle and the second baffle are elastically connected by a first spring, and the guide groove A filter screen is embedded inside, an arc-shaped groove is opened on the inner wall of the annular groove, and a water supply pipe communicating with the annular groove is embedded in the roadbed. In the present invention, the rainwater containing a large amount of pollutants in the initial stage is introduced into the sewage treatment system through the sewage pipe, and as time goes by, the road is gradually washed away by the rainwater, and the relatively clean rainwater in the later stage can be directly imported into the designated place through the water supply pipe for collection, so The staged treatment of rainwater on the road surface not only ensures the absorption efficiency of rainwater in the sponge city, but also treats polluted water sources.

Description

technical field [0001] The invention relates to the relevant technical field of sponge city municipal construction, in particular to a sponge city road drainage system. Background technique [0002] In the construction process of sponge city, the design of drainage system is particularly important, especially for some southern cities with frequent rains, the discharge of road water is very critical. [0003] When building a sponge city, it is often necessary to collect rainwater and discharge it to a designated location when it is used. Since the rainwater on the road flows, it often carries a large amount of road pollutants, and the rainwater needs to be treated by the sewage treatment system first. However, if all the rainwater on the road surface is directly discharged into the sewage treatment system, the pressure on the urban sewage treatment system will be sharply increased, resulting in low efficiency of rainwater drainage on the road surface and causing water accumul...

[0003] When building a sponge city, it is often necessary to collect rainwater and discharge it to a designated location when it is used. Since the rainwater on the road flows, it often carries a large amount of road pollutants, and the rainwater needs to be treated by the sewage treatment system first. However, if all the rainwater on the road surface is directly discharged into the sewage treatment system, the pressure on the urban sewage treatment system will be sharply increased, resulting in low efficiency of rainwater drainage on the road surface and causing water accumulation on the road, which will not only affect traffic, but also reduce the cost of sponge cities.
