Pavement rainwater eliminating, purifying and automatic-cleaning system and mounting system thereof

Abstract

The invention discloses a pavement rainwater eliminating, purifying and automatic-cleaning system and a mounting system thereof. The system comprises a plurality of manhole cover plates, water discharging devices, automatic cleaning devices, a collecting, purifying and reusing device and an accumulated water depth pre-alarm device; the water draining devices are positioned below the manhole coverplates, every water discharging device comprises a guiding tank, a vertical water discharging tube and a filter screen layer, the filter screen layer comprises a pedestal, and filter screen plates andtelescopic plates which are alternately arranged at intervals, every automatic cleaning device comprises a main dedusting tube, a vertical dedusting tube and a nozzle, the collecting, purifying and reusing device comprises a sedimentation tank, a water reservoir, a communicating tube, a rainwater nozzle, a large-power water pump and a sponge body, and the accumulated water depth pre-alarm devicecomprises a rainfall detector, a water depth display and a PLC chip machine; and the water discharging ability and the arrangement quantity of the water draining devices are calculated and determinedaccording to the designed water discharging volume, and the water draining devices have three working modes. The system has water discharging, pavement accumulated water pre-alarming and water storingfunctions, and also has an automatic cleaning function.

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.
