In the above-mentioned road surface drainage system, the road surface structure 100 can be permeable to water, and rainwater can permeate into the road surface structure 100 after falling to the surface of the road surface structure 100, and then enter the drainage channel 260 through the first side wall 210 of the drainage structure 200. Even if the road surface drainage system meets the condition of high-strength rainstorm, water seeping into the road surface structure 100 can also seep into the drainage channel 260 of the drainage structure 200 in time, so that the phenomenon of water accumulation on the road surface is avoided, rainwater can be prevented from staying in the road surface structure 100 for a long time, and the bearing capacity of the road surface structure 100 is ensured.
In one embodiment, the first sidewall 210 is adjacent to the pavement structure 100. Specifically, drainage structure 200 sets up at road surface structure 100 along the side of length direction, and first lateral wall 210 is adjacent with the side of road surface structure 100, and like this, the water in road surface structure 100 can permeate first lateral wall 210 fast, and enter into drainage channel 260 to reduce the time that water enters into drainage channel 260 from road surface structure 100, avoid causing the surface of the road ponding phenomenon.
Alternatively, the first sidewall 210 may be made of large pore concrete, such as sand free concrete.
Further, the drainage structure 200 further includes a bottom wall 230 connected to the first sidewall 210, and a second sidewall 220 connected to the bottom wall 230, the second sidewall 220 is disposed opposite to the first sidewall 210 at a distance, and the first sidewall 210, the bottom wall 230, and the second sidewall 220 cooperate to form a drainage channel 260. The first sidewall 210, the second sidewall 220, and the bottom wall 230 cooperate to form a drain that allows water to enter the drain channel 260 when the water passes through the first sidewall 210.
