Description

A road drainage device and drainage method thereof

technical field

The invention relates to the field of water conservancy, in particular to a road drainage device and a drainage method thereof.

Background technique

In the current road drainage system, since the water flow of the manhole cover is fixed, in case of heavy rain, when the rainfall is much greater than the amount of water flowing into the drainage system, the rainwater will accumulate on the road surface, causing the road surface to be flooded. Set more drainage holes on the top to increase the amount of water flowing into the drainage system to improve the drainage capacity of the road. This method will cause excessive damage to the cross-sectional area of the manhole cover and reduce the bearing capacity of the manhole cover. A drainage hole is not conducive to the comfort of driving, and cannot guarantee the safety of pedestrians.
