AI Technical Summary
When existing cement concrete pavement faces increased traffic loads and heavy rainstorms, it is easy to form water on the surface, resulting in attenuation of drainage and anti-slip properties, and traffic safety is threatened.
A drainage pavement structure is designed, including the base layer, drainage layer, seepage layer and pavement layer. The drainage layer is formed by a reinforcement plate and a reinforcement net to form a drainage trough to discharge rainwater; the seepage layer penetrates the rainwater into the reinforcement layer and discharges it through the drainage trough; small bumps are set on the pavement layer to increase friction; and a waterproof layer is set on the reinforcement plate to prevent rainwater from penetrated into the base layer.
It effectively reduces the water area of the road, improves the drainage and anti-slip performance of the road surface, enhances the strength and durability of the road structure, and ensures the safety of the road traffic.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pavement and relates to a drainage pavement structure. Background Art
[0002] In recent years, my country's road construction has developed rapidly, especially cement concrete pavement, which has been widely used in my country as one of the main forms of high-grade pavement. However, with the increase in road traffic volume and traffic load, the depth of the original cement pavement anti-skid structure has become smaller, and it is easy to form water on the road surface, thereby reducing the pavement drainage performance and anti-skid performance. The road traffic safety cannot be guaranteed. In order to solve this problem, designing a new type of drainage pavement structure is an important solution.
[0003] The current drainage pavement structure mostly uses cement pavement grooves and an asphalt overlay. Although it has drainage performance, it has poor pavement durability and rapid degradation of anti-skid drainage performance. At the same time, when the road drainage system encounters a very heavy rainstorm, the water pressure inside the drainage system may form backflow and cause backflow to the road. Utility Model Content
[0004] The utility model aims to solve the above problems in the prior art and proposes a drainage pavement structure.
[0005] The purpose of the utility model can be achieved through the following technical solutions: a drainage pavement structure, including a base layer, a drainage layer is arranged on the base layer, a water seepage layer is arranged on the drainage layer, and a pavement layer is arranged on the water seepage layer. The drainage layer includes a reinforcing plate and a plurality of reinforcing meshes arranged on the base layer, the reinforcing meshes are woven from transverse steel bars and longitudinal steel bars, and every two transverse steel bars are woven with the longitudinal steel bars to form a through hole, and a drainage groove is arranged on the top of the reinforcing plate, and the drainage groove is inclined from the middle to the two ends.
[0006] In the above drainage pavement structure, a plurality of small convex points are arranged on the pavement layer, and the arrangement of the convex points can increase the friction between the pavement and the automobile tires, and improve the anti-skid effect of the pavement.
[0007] In the above drainage pavement structure, a waterproof layer is provided on the reinforcement plate, which can improve the waterproof effect of the reinforcement plate, prevent rainwater from penetrating into the base layer, and prevent rainwater from eroding the base layer and causing the collapse of the road surface.
[0008] In the above-mentioned drainage pavement structure, both ends of the drainage groove penetrate the reinforcing plate.
[0009] In the above drainage pavement structure, filter screens are arranged on both sides of the reinforcement layer, which can effectively prevent stones or other garbage on both sides from entering the reinforcement layer, thereby affecting the drainage effect of the reinforcement layer.
[0010] Compared with the prior art, the utility model has a water-permeable layer and a reinforcement layer. The water-permeable layer can penetrate rainwater on the road surface into the reinforcement layer, and discharge rainwater from both sides of the road surface through the drainage grooves on the reinforcement plate, effectively reducing road surface water accumulation; the reinforcement layer can effectively improve the strength of the road surface structure through a reinforcement mesh woven with multiple layers of stainless steel.
