[0002] The pavement structure generally includes a multi-layer structure, which includes, from bottom to top, the roadbed, the base layer made of cement, sand and gravel, the waterproof layer made of cement, gravel, etc., and the pavement layer. At the same time, drainage ditches are set on both sides. The pavement layer is generally made of asphalt. Asphalt pavements mixed in different proportions often have a certain degree of drainage, so that the pavement structure has a drainage function. In order to deal with road waterlogging caused by heavy rain, the pavement layer of the pavement structure can be set to be inclined so that the water can be more smoothly diverted to the drainage ditch on the side. However, in the face of heavy rain, the drainage function of the pavement structure may not meet the drainage needs. At the same time, the drainage ditch may overflow and cause the accumulated water to spread to the road surface, eventually causing serious road waterlogging, which may endanger the safety of vehicles.

[0025] In an exemplary embodiment, Figure 1 , 2 As shown, this embodiment provides a drainage pavement structure, which includes a roadbed 1, a base layer 2, a waterproof layer 3 and a pavement layer 4 arranged in sequence from bottom to top, and drainage ditches 5 arranged on both sides, the top surface of the pavement layer 4 is a slope structure with a high middle and low sides, and the lower top surfaces of the pavement layer 4 on both sides are connected to the two drainage ditches 5 respectively;

[0026] It also includes an isolation groove 6 arranged in the middle of the slope structure. A flow guide pipe 7 is also arranged in the base layer 2, and both ends of the flow guide pipe 7 are respectively connected to the isolation groove 6 and the outside.

[0027] In the above embodiment, the pavement structure provided is a slope structure with a high middle and low sides as a whole and is provided with an isolation ditch 6. The drainage ditches 5 on both sides are used for drainage during light rainfall, and the isolation ditch 6 can allow accumulated water to enter during heavy rainfall, and then be diverted to the outside of the pavement structure through the provided guide pipe 7, thereby realizing the drainage function more quickly, solving the problem that the existing technology may cause serious water accumulation on the road surface when facing heavier rainfall; the structure of each layer in this embodiment is similar to that in the existing technology, wherein the base layer 2 is provided with the guide pipe 7 preset before pouring, and then pouring is performed, and finally To form an overall structure, further, a U-shaped rod 8 buckled on each guide pipe 7 is also arranged in the base layer 2, so that the guide pipe 7 can be protected and its stability can be enhanced. In particular, the guide pipe 7 and the U-shaped rod 8 can be made of steel, which has great mechanical strength. A steel bar structure can also be arranged in the base layer 2 to further improve the mechanical strength. Furthermore, the two tips of the U-shaped rod 8 can be spike-shaped, so that it can be inserted into the roadbed 1 for positioning, and when the base layer 2 is poured, it can also have a better stabilizing effect.

[0028] In a further exemplary embodiment, Figure 1As shown, it also includes a pair of shoulders 9 arranged above both sides of the roadbed 1, two drainage ditches 5 are respectively arranged on the two shoulders 9, and the base layer 2, the waterproof layer 3 and the pavement layer 4 are all arranged between the two shoulders 9. The arranged guide pipe 7 can pass through the shoulders 9 and extend outside the structure.

[0029] In a further exemplary embodiment, Figure 1 As shown, the slopes on both sides of the slope structure are α, 1°≤α≤4°, that is, a relatively small amount of accumulated water can flow toward both sides. A number of ditch plates 14 are overlapped on the top surface of the drainage ditch 5, and each ditch plate 14 is provided with a through hole 15, through which the water enters the drainage ditch 5 to achieve the drainage function.

[0030] In a further exemplary embodiment, Figure 1 As shown, the guide pipe 7 includes multiple ones located on one side of the isolation groove 6, or multiple ones on both sides, and one end of the guide pipe 7 connected to the isolation groove 6 is higher than the other end. It can be adaptively selected according to specific road conditions. For example, if one side has a lower position (lower than the guide pipe 7), it is set on one side, or if both sides have a lower position, it can be set on one side or both sides.

[0031] In more specific scenarios, Figure 1 , 2 As shown, the surface layer includes a lower asphalt layer 10 covering the waterproof layer 3 and an upper asphalt layer 11 covering the lower asphalt layer 10. The upper asphalt layer 11 is in direct contact with the vehicle, while the lower asphalt layer 10 plays an auxiliary supporting role. In more detail, the inner wall of the isolation ditch 6 is covered with a waterproof layer 16 to prevent the isolation ditch 6 from leaking.
