Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 4, a self-draining pavement includes: the water-permeable floor consists of a water-permeable layer 1 and a water drainage layer 2, wherein the water-permeable layer 1 and the water drainage layer 2 are distributed from top to bottom; the permeable layer 1 is made of permeable concrete with a permeable function, and the surface of the permeable layer 1 is of a plane structure; the drainage layer 2 does not have the water permeability and water permeability functions, the surface of the drainage layer 2 is composed of at least one inclined surface 3 or one combined inclined surface 3, and the contact surface of the drainage layer 2 and the bottom surface of the water permeable layer 1 is the inclined surface 3; the bottom surface of the permeable layer 1 is positioned above the roadbed, and the contact surface of the permeable layer and the roadbed is a plane.

Specifically, water flows downwards from the water permeable layer 1 to the surface of the drainage layer 2, and the water is drained to one side or two sides of the road surface along the inclined surface 3 of the drainage layer 2. Since the drainage layer 2 is located inside the road surface below the water permeable layer 1, the drainage process is performed inside the road surface. And the surface of the permeable layer 1 on the road surface is a flat plane. Therefore, the fitness of the sports is met to the greatest extent during walking, running and riding, and the fitness of the sporter is protected.

And the permeable concrete adopted by the permeable layer 1 is laid on the surface of the drainage layer 2. The permeable concrete has pores with different sizes, and water flow can flow downwards to the surface of the drainage layer 2 from gaps among the permeable concrete particles with different sizes and diameters. The surface of the drainage layer 2 is a hardened surface formed by paving cement, asphalt or stone, and has no water permeable function. No leakage occurs when water flows on the drainage layer 2. The surface of the drainage layer 2 is the inclined plane 3 with one high end and the other low end, so that water can be drained towards the side of the channel. The inclined plane 3 can also be the highest point in the middle of the road, the heights of the two sides are lower, and water flows are discharged from the middle of the road to the two sides of the road. The inclined plane 3 of the drainage layer 2 can also be a continuous serrated surface, and the serrated surface drains water to the next serrated surface through water storage and drainage. In this way, the water streams are discharged one by one from the middle of the path to both sides of the path. Wherein, the height of the drainage starting point of the sawtooth surface is higher than that of any sawtooth. The drainage surface can also be a convex structure with a circular arc shape.

After the inclined surface 3 of the drainage layer 2 is manufactured, pervious concrete is poured on the surface of the drainage layer 2, the pervious concrete is fully contacted with the inclined surface 3 of the surface of the drainage layer 2 and is solidified and connected, and meanwhile, the surface of the pervious layer 1 is integrally paved into a plane. The permeable layer 1 has a certain thickness, so that when water on the surface of the drainage layer 2 is gathered to form a certain height, water cannot seep out of the surface of the drainage layer 2 to the surface of the permeable layer 1. The angle of the drainage layer 2 can be set as required, and the larger the area with larger water amount is, the larger the angle of the inclined plane 3 of the drainage layer 2 is, and the better the drainage effect is. Conversely, the smaller the inflow amount, the smaller the angle of the inclined surface 3 of the drainage layer 2 is, but the requirement of drainage at ordinary times can be satisfied.
