Description

Technical Field

[0001] This utility model relates to the field of roads, and in particular to a permeable road. Background Technology

[0002] Permeable pavement is an environmentally friendly road paving system that uses special materials and structural design to allow rainwater to quickly infiltrate into the ground or drain out, thereby reducing surface runoff, alleviating urban flooding, and replenishing groundwater.

[0003] However, existing permeable roads require layer-by-layer construction on-site, which results in slow construction efficiency.

[0004] Therefore, it is essential to invent a permeable road. Utility Model Content

The drainage cavities of the permeable precast blocks 1, 2, and 3 are combined to form a drainage channel.

[0006] The permeable precast blocks 1, 2, and 3 are respectively provided with a surface permeable layer, a middle reinforcing layer, and an inner permeable layer from top to bottom on their upper surfaces. The permeable pores of the surface permeable layer are larger than those of the middle reinforcing layer, and the permeable pores of the inner permeable layer are larger than those of the surface permeable layer.

[0007] The permeable precast block 1, permeable precast block 2, and permeable precast block 3 are all in an I-shape.

[0008] The permeable precast blocks 1, 2, and 3 are internally filled with steel reinforcement frames of the same shape.

[0009] The intermediate reinforcing layer is filled with basalt fibers or polypropylene fibers.

[0010] The permeable precast block 1 has a splicing groove 1 on the side near the drainage cavity, and the permeable precast block 1 is connected to the corresponding permeable precast block 2 through the splicing groove 1.

[0011] The permeable precast block 2 is provided with integrated splicing blocks on both sides near the drainage cavity. One of the splicing blocks on one side of the permeable precast block 2 is engaged with the splicing groove 1. The permeable precast block 2 is connected to the corresponding permeable precast block 3 through the splicing block.

[0012] The permeable precast block three has splicing grooves two on both sides near the drainage cavity, and the permeable precast block three is snapped into the corresponding splicing block through the splicing grooves two.

[0013] Compared with the prior art, the advantages of this utility model are: The modular design of this utility model facilitates rapid on-site assembly into a permeable road, avoiding the hassle of laying it layer by layer, thereby improving construction efficiency. It also makes it easier to replace damaged parts individually later. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings: Example Reference Figure 1-4 A permeable road includes a permeable precast block 1, a permeable precast block 2, a permeable precast block 3, and a drainage chamber 4. The permeable precast blocks 2 and 3 are alternately connected to form a permeable road. The permeable precast block 1 is installed at the end of the permeable road and is connected to the corresponding permeable precast block 2. By setting up the permeable precast blocks 1, 2, and 3, they can be prefabricated in the factory and then transported to the construction site for on-site assembly, thereby improving on-site construction efficiency. Specifically, each of the permeable precast block 1, permeable precast block 2, and permeable precast block 3 has a drainage cavity 4 that runs through it. The drainage cavities 4 between the permeable precast blocks 1, 2, and 3 form a drainage channel. Through the setting of the drainage channel, water can enter the drainage channel through the surface permeable layer 9, the intermediate reinforcing layer 10, and the internal permeable layer 11, and then be discharged through the drainage channel to prevent the foundation from being eroded. Specifically, the inner surface of the drainage cavity 4 is provided with a waterproof coating.

[0022] Specifically, the upper surfaces of permeable precast blocks 1, 2, and 3 are respectively provided with a surface permeable layer 9, a middle reinforcing layer 10, and an internal permeable layer 11 from top to bottom; Surface permeable layer 9: Made of permeable concrete with high porosity (15%-25%), 5-8cm thick, with pore diameter of 1-3mm, responsible for rapid drainage and filtering large particulate impurities; Intermediate Reinforcing Layer 10: Composed of high-strength fiber-reinforced permeable concrete (fiber content 0.5%-2%), with a thickness of 8-12cm, porosity of 8%-15%, and pore diameter of 0.5-1.5mm, providing the main load-bearing capacity and preventing surface layer settlement; Internal permeable layer 11: permeable concrete (particle size 10-30mm), thickness 10-15cm, porosity 25%-35%; This creates a gradient pore structure for better drainage and filtration; The surface permeable layer 9 and the inner permeable layer 11 are coated with a superhydrophobic nano-coating (such as silica nanoparticles) to reduce the adhesion of pollutants, and can be self-cleaned by rainwater.

[0023] Specifically, the permeable precast block 1, permeable precast block 2, and permeable precast block 3 are all in an I-shape. This structure ensures the bonding and stability with the foundation when they are buried in the ground.

[0024] Specifically, permeable precast blocks 1, 2, and 3 are filled with steel reinforcement cages 8 of the same shape to improve the overall strength. Specifically, the outer surface of the steel reinforcement cage 8 is provided with an anti-corrosion coating, such as epoxy resin coating, hot-dip galvanized coating, composite coating, paint anti-corrosion coating (such as zinc-rich primer), electric arc spraying anti-corrosion coating, etc.

[0025] Specifically, the intermediate reinforcing layer 10 is filled with basalt fiber or polypropylene fiber at a dosage of 0.5%-2%, which can significantly improve crack resistance and fatigue resistance, and the compressive strength can reach 30-40MPa (far exceeding the 20MPa of ordinary permeable concrete).

[0026] Specifically, the permeable precast block 1 has a splicing groove 5 on the side near the drainage cavity 4.

[0027] Specifically, the permeable precast block 2 has integrated splicing blocks 6 on both sides near the drainage cavity 4, and one of the splicing blocks 6 on one side of the permeable precast block 2 is engaged with the splicing groove 5.

[0028] Specifically, the permeable precast block 3 has splicing grooves 2 7 on both sides near the drainage cavity 4, and the permeable precast block 3 is snapped into the corresponding splicing block 6 through the splicing grooves 2 7.

[0029] In this embodiment, during use, an appropriate number of permeable precast blocks 1, 2, and 3 are selected according to the construction site conditions and assembled on site, such as... Figure 1 As shown, it is pre-embedded in the foundation, and after pre-embedding, the surface permeable layer 9 is flush with the road surface; In this way, during rainy days, rainwater will pass through the surface permeable layer 9, the middle reinforcing layer 10 and the inner permeable layer 11 into the drainage channel formed by the combination of the drainage chamber 4, and then be discharged to the designated location through the drainage channel.

[0030] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
