Drainage system for municipal roads

Abstract

The invention relates to a drainage system for municipal roads, and belongs to the technical field of municipal road drainage. The drainage system comprises a first drainage outlet, a second drainageoutlet and a drainage ditch, wherein the first drainage outlet is arranged on the edge of a road surface; the second drainage outlet is arranged on the side surface of a sidewalk; the drainage ditch is located below a road; a drainage channel is arranged between the second drainage outlet and the drainage ditch and is connected to the side surface of the drainage ditch; a supporting cover is arranged at the bottom of the drainage ditch below the first drainage outlet, is connected to the bottom of the drainage ditch through an elastic part and can move up and down to open or close a water outlet of the lower end of the drainage channel; the supporting cover comprises a box body with an opening on the lower side surface and a water receiving plate arranged on the upper surface of the box body; and the box body is connected to the water receiving plate through a supporting rod. The drainage system can adjust the drainage amount of the drainage outlets according to the amount of accumulated water on the road, achieves a relatively good drainage effect and reduces the wasting of resources.

Description

technical field [0001] The invention relates to the technical field of municipal road drainage, in particular to a municipal road drainage system. Background technique [0002] Road drainage is very important in the process of urban construction planning. The drainage capacity of urban roads has a great impact on urban traffic safety in rainy days. If the drainage capacity of urban roads is not strong, it will lead to excessive water accumulation on the roads during rainy days. Many, making it difficult for the vehicle to drive, or the occurrence of traffic accidents caused by problems in the process of driving. [0003] The Chinese utility model patent with the authorized announcement number CN207109989U discloses a convenient drainage system for municipal roads, which mainly includes a first sewer pipe, a first drainage channel, a main drainage pipe, a second sewer pipe, a second drainage channel, sidewalks, a The second drainage outlet, the first drainage outlet and the ...

AI Technical Summary

Problems solved by technology

[0004] The existing technical solutions mentioned above have the following defects: although the pressure of urban flood discharge can be relieved to a certain extent, the construction of two sets of drainage systems is difficult and the construction cost is relatively high. For some areas with less precipitation, Establishing two sets of drainage systems will cause a waste of resources
