Description

Technical Field

[0001] The utility model relates to the technical field of concrete pavements, in particular to a thin-layer permeable concrete pavement structure. Background Technique

[0002] A concrete pavement generally consists of four parts: subgrade, base course, cushion course, and surface course. The main material of the surface course is concrete, which generally requires wear resistance, flatness, skid resistance, high strength, etc.; the cushion course is set on roads with unsuitable temperature and humidity conditions, aiming to change the pavement structure, and the base course should have strong anti-deformation ability, compression resistance, scouring resistance, and firmness; plain concrete is ordinary concrete, and this kind of concrete is only equipped with steel bars at the joint edges and a few ranges; a reinforced concrete pavement means that steel bars are arranged horizontally and vertically inside the pavement to form a steel bar network; a continuously reinforced concrete pavement means a kind of concrete with continuously arranged steel bars in the road slab.

[0003] Chinese authorized announcement number CN208219332U discloses a permeable pavement, which includes a graded crushed stone cushion layer, a permeable cement concrete layer, and an open-graded asphalt mixture layer arranged from bottom to top in sequence. The thickness of the open-graded asphalt mixture layer is 1-2 cm. The permeable cement concrete layer and the open-graded asphalt mixture form a composite pavement structure, which not only has the advantages of the comfort of the asphalt pavement but also has the advantages of the compactness of the cement concrete. On this basis, the compactness of the permeable cement concrete layer makes the dust and garbage on the road surface only stay in the open-graded asphalt mixture layer; by reasonably setting the thickness of the open-graded asphalt mixture layer and making it thinner, the dust and garbage can be easily washed away by rain or the water sprayed by a sprinkler truck and will not affect the permeable function due to blockage. This utility model is used in the field of urban road construction.

[0004] In the existing concrete pavement structure, the surface layer uses high-strength concrete, resulting in inconvenient drainage of accumulated water on the concrete pavement. If a permeable concrete pavement is used, the strength of the pavement is poor, it cannot bear heavy weights, and it is easy to be damaged. For this reason, we propose a thin-layer permeable concrete pavement structure. Content of the Utility Model

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-3 , a thin-layer permeable concrete pavement structure, including a concrete surface layer 1, and a plurality of drain pipes 4 are arranged inside the concrete surface layer 1; the drain pipes 4 are uniformly distributed along the inside of the concrete surface layer 1, and the drain pipes 4 are in a triangular structure. Three connecting pipes 7 are installed above the drain pipes 4, a water collecting box 5 is fixedly installed above the connecting pipes 7, and permeable bricks 6 are installed inside the water collecting box 5; the drain pipes 4 are communicated with the connecting pipes 7, and the connecting pipes 7 are communicated with the permeable bricks 6; the shape and size of the permeable bricks 6 match the shape and size inside the water collecting box 5. A concrete base layer 2 is installed below the concrete surface layer 1; heat conduction rods 3 are installed between two adjacent drain pipes 4; the heat conduction rods 3 penetrate through the inside of the concrete surface layer 1, and the heat conduction rods 3 are uniformly distributed along the inside of the concrete surface layer 1; by uniformly arranging a plurality of heat conduction rods 3, the heat inside the concrete surface layer 1 can be discharged, avoiding damage caused by overheating of the concrete surface layer 1. A connecting rod 8 is installed between the adjacent heat conduction rods 3 and drain pipes 4; the heat conduction rods 3 are fixedly connected with the connecting rod 8, and the connecting rod 8 is fixedly connected with the drain pipes 4; by arranging the permeable bricks 6, connecting pipes 7 and drain pipes 4 in cooperation to discharge the accumulated water on the surface of the concrete surface layer 1, the drainage capacity of the concrete pavement structure is improved, avoiding road surface water accumulation. At the same time, the volume of the permeable bricks 6 is small, so the force on the permeable bricks 6 is small and they are not easily damaged.

[0022] Working principle: When using this thin-layer permeable concrete pavement structure, first, when it rains or there is accumulated water on the road surface, the accumulated water penetrates through the permeable bricks 6 and enters the inside of the connecting pipes 7 and is then discharged by the drain pipes 4, thereby avoiding accumulated water on the upper surface of the concrete surface layer 1 affecting vehicle driving. Then, when the permeable bricks 6 are damaged, they can be taken out from the water collecting box 5 and replaced. Secondly, when the concrete surface layer 1 is overheated, the heat will be transferred to the heat conduction rods 3. When the wind blows past the part of the heat conduction rods 3 extending out of the concrete surface layer 1, the heat on the heat conduction rods 3 is taken away, thereby playing a role in dissipating heat for the concrete surface layer 1. Thirdly, the heat conduction rods 3, drain pipes 4 and connecting rods 8 form a network, enhancing the overall strength of the concrete surface layer 1. This is the working principle of this thin-layer permeable concrete pavement structure.

[0023] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model.
