A self-cleaning system for removing and purifying road surface rainwater and its installation method

Abstract

The invention discloses a road surface rainwater removal and purification self-cleaning system and an installation method thereof, comprising several inspection shaft cover plates arranged along the road width direction, a drainage device, a self-cleaning device, a collection, purification and reuse device, and a water accumulation depth warning device; The device is located under the manhole cover, including a diversion pool, a vertical drain pipe, and a filter layer. The filter layer includes a base, alternately arranged filter plates, and telescopic plates. The self-cleaning device includes a dust removal main pipe and a dust removal vertical pipe. , sprinklers, collection, purification and reuse devices include sedimentation tanks, reservoirs, connecting pipes, rainwater nozzles, high-power water pumps, sponges, water depth early warning devices include rainfall detectors, water depth displays and PLC chip machines; drainage device drains The water capacity and layout quantity are calculated and determined according to the design displacement, and have three working modes; the system of the present invention has drainage function, road surface water warning function, water storage function, etc., and has self-cleaning function at the same time.

Description

technical field [0001] The invention belongs to the technical field of road drainage and application, in particular to a self-cleaning system and an installation method for rapid drainage, collection, purification and reuse of rainwater on low-lying road sections or sponge cities. Background technique [0002] With the rapid development of urbanization in China today, the urban population continues to increase, the industry develops rapidly, and the problem that municipal drainage system construction lags behind urban construction is becoming more and more prominent. In particular, some cities do not pay attention to the influence of topography during the construction process, so that many low-lying places appear after the completion of urban road construction, and it is difficult to discharge the accumulated water in time after the heavy rain. The stagnant water has been difficult to get rid of for a long time, causing great difficulties for pedestrians and vehicles to trav...

AI Technical Summary

Problems solved by technology

In particular, some cities do not pay attention to the influence of topography during the construction process, so that many low-lying places appear after the completion of urban road construction, and it is difficult to discharge the accumulated water in time after the heavy rain. The stagnant water is difficult to get rid of for a long time, causing great difficulties for pedestrians and vehicles to travel

Intersections are an extremely important part of urban roads. They are the places where vehicles and pedestrians gather, turn and evacuate. Most of the rainwater outlets are arranged equidistantly according to local customs without calculation. When drainage congestion occurs in a large area of ​​the city, it often takes a long time for the accumulated water to be drained, which brings huge hidden dangers to traffic safety.

[0003] At the same time, a large amount of rainwater containing suspended solids and harmful metal ions directly enters the urban pipe network through the rainwater outlet and is discharged into nearby waters, causing water pollution in the waters.
