Road drainage device for sponge city

Abstract

The invention discloses a road drainage device for a sponge city. The device comprises drainage channels dug in two sides of a road. A ditch cover plate is embedded in the drainage channel; a circulargroove is also dug below the road; and the circular groove is connected with the drainage channel through a water inlet pipe, a partition plate is rotatably connected into the circular groove in a sealed mode, an upper end of the partition plate is made of an iron material, a permanent magnet is embedded in an inner top of the circular groove, a conveying pipe is arranged on the inner wall of thecircular groove, and a discharging pipe is arranged at the inner bottom of the circular groove. By arranging the circular groove, the conveying pipe and the discharging pipe, rainwater can be collected, meanwhile, the conveying pipe and the discharging pipe can treat the rainwater in different periods, waste caused by rainwater losses is avoided, and meanwhile pollution caused by a fact that surface pollutants flow into a municipal water supply system or a river area along with the rainwater is prevented.

Description

technical field [0001] The invention relates to the technical field of sponge city municipal equipment, in particular to a road drainage device for a sponge city. Background technique [0002] Sponge city can absorb water, store water, infiltrate water, purify water when it rains, release and use the stored water when needed, so that the city can adapt to environmental changes and deal with natural disasters caused by rainwater. [0003] Because there are many other pollutants such as garbage on urban roads, during the rainy season, especially in heavy rain, the rainwater falling on the ground will wash away these pollutants and enter the urban drainage system. If they are directly discharged to rivers The area will pollute rivers and cause water loss and waste, which is not in line with the design concept of a sponge city. If it is all input into the municipal sewage treatment system for treatment, it will greatly increase the pressure on the sewage treatment system. In vi...

[0003] Because there are many other pollutants such as garbage on urban roads, during the rainy season, especially in heavy rain, the rainwater falling on the ground will wash away these pollutants and enter the urban drainage system. If they are directly discharged to rivers The area will pollute the rivers and cause water loss and waste, which does not conform to the design concept of the sponge city. If all of them are input into the municipal sewage treatment system for treatment, the pressure on the sewage treatment system will be greatly increased
