Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1, in this embodiment: a permeable anti-slip pavement structure is composed of a rammed soil layer 1, a cushion layer 2, a base layer 3 and a surface layer 4, wherein anti-slip aggregate is paved on the surface layer 4, an anti-slip aggregate shell improves the anti-slip function of a pavement, drainage slopes 5 are arranged on two sides of the surface layer 4, a drainage channel 6 is arranged at the slope bottoms of the drainage slopes 5 on two sides, when the precipitation amount is large, water which does not go down on the pavement flows into the drainage channel along the drainage slopes 5 in a runoff manner, the surface layer 4 is arranged above the base layer 3, the base layer 3 is arranged above the cushion layer 2, the cushion layer 2 is arranged above the rammed soil layer 1, a waterproof layer 7 is arranged between the rammed soil layer 1 and the cushion layer 2, two drainage blind pipes 8 are pre-buried in the cushion layer 2, the drainage blind pipes 8 have extremely high surface water seepage capability and internal water communication capability, water in the cushion layer 2 can permeate the drainage blind pipes 8 and then drain through the drainage blind pipes 8, the two drain blinders 8 are arranged above the waterproof layer 7, the two drain blinders 8 are communicated with the drain channels 6 on the two sides through pipelines, water flowing into the drain channels 6 can flow into the drain blinders 8 through the pipelines, then is drained through the drain blinders 8, the drain channels 6 are communicated with the drain blinders 8, meanwhile, the water in the drain channels 6 can be prevented from overflowing excessively, the two drain blinders 8 are respectively arranged beside the two drain channels, the two drain blinders 8 are respectively arranged below the drain slopes 5 on the two sides, because the drain blinders 8 are not arranged under the surface layer 4, the load from the road surface is not pressed on the drain blinders 8, the drain blinders 8 are prevented from being deformed by pressure, the surface layer 4 mainly consists of coarse aggregate, fine aggregate and filler, wherein the coarse aggregate accounts for the maximum ratio, the load from the surface layer 4 is born by the action of the base layer 3, the basic unit 3 is paved by open graded asphalt stabilized macadam, large-grain diameter water permeability asphalt mixture or porous water permeable concrete, the load of the diffusion basic unit 3 of the effect of bed course 2, bed course 2 is paved by open graded aggregate, coarse sand or rubble and forms, the top of rammed soil layer 1 is approximately arch-shaped, waterproof layer 7 of laying between rammed soil layer 1 and bed course 2 is arch-shaped too, drainage blind pipe 8 is located the extreme position on arch both sides, the water that permeates surface course 4, basic unit 3 and bed course 2 can be finally by waterproof layer 7 drainage to the drainage blind pipe 8 on arch both sides.
