Early warning device and early warning method for pavement rainwater drainage

Abstract

The invention discloses an early warning device and an early warning method for pavement rainwater drainage. The early warning device comprises a rainfall detection instrument, a water depth display and a PLC chip machine which are arranged on a marginal strip in the inlet direction of a road, wherein the rainfall detection instrument, the water depth display and the PLC chip machine are electrically connected; the rainfall intensity data measured by the rainfall detection instrument is transferred to the PLC chip machine in real time and is computed by the PLC chip machine, and then, pavementwater depth data is displayed on the water depth display; a drainage device is arranged in an intersection of concave-shaped, valley-shaped or saddle-shaped terrains or in the lowest pit of a concave-shaped vertical curve of a road section; a pressure sensor is arranged in the lowest pit of the pavement; the pressure sensor is flush with the pavement; and the pressure sensor is electrically connected with the PLC chip machine. The early warning device disclosed by the invention can prompt early warning for road water accumulation depth, has a quick drainage function, achieves the purpose of maximum and quick drainage, and meets the road traffic safety.

Description

technical field [0001] The invention belongs to the technical field of road drainage and application, in particular to a road surface rainwater drainage early warning device and an early warning method for 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 travel. Intersections are an extremel...

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.
