The present embodiment provides a road surface drainage system 10 with at least the following advantages:

when water level sensor 500 detects that the water level is equal to or higher than the preset water level, first valve 400 is opened, and second valve 410 is closed, then road surface ponding discharges in cylinder body 200 through inlet tube 300, removes through promoting piston rod 210, drives to comb and leaks and open lower mouth of a river 700, and increase displacement reduces road surface ponding, avoids road surface water level too high. In the process that the water level does not fall to be lower than the preset water level, the second valve 410 is closed all the time, water is always in the cylinder body 200, the grate leakage is always opened, the surface water can be directly discharged into the sewer 710 through the sewer port 700 all the time, and the drainage efficiency is improved. When the water level drops to be lower than the preset water level, the second valve 410 is opened, the first valve 400 is closed, the second valve 410 is opened, the water in the cylinder body 200 is discharged through the water outlet pipe 310, the grate leakage is closed, and the water outlet 700 recovers the usual water discharge amount. The first valve 400 is closed, and when the water level is avoided to be lower, water flows into the cylinder body 200 again, leads to the comb to leak and opens once more, closes the back when next water level risees, and the first valve 400 can in time be opened, and the comb leaks and can in time be opened.

Embodiments of the present invention also provide a method of controlling a roadway drainage system 10. The control method of the road surface drainage system 10, which is executed by the controller 600, includes:

The step of controlling the first valve 400 to be opened or closed according to the water level signal, and the step of controlling the second valve 410 to be opened or closed includes: when the water level value represented by the water level signal is equal to or greater than the preset water level value, the first valve 400 is opened, and the second valve 410 is closed, and when the water level value represented by the water level signal is less than the preset water level value, the second valve 410 is opened, and the first valve 400 is closed.

When the water level rises to or above the preset water level, the first valve 400 is opened, the surface water enters the cylinder body 200 through the water inlet pipe 300 to push the grate to be opened, and meanwhile, a large amount of water on the surface flows into the sewer 710 through the opened water outlet 700, so that the water discharge is increased, and the surface water is avoided; the water level does not reduce, then the water in the cylinder body 200 persists all the time, and the comb leaks and opens all the time, when falling to being less than preset water level until the water level, the water in the cylinder body 200 passes through outlet pipe 310 and discharges into sewer 710, and the comb leaks and closes, and the ponding on road surface will leak through the comb this moment and just can flow into sewer 710, reduces displacement.
