Description

Technical Field

[0001] The utility model relates to the technical field of municipal roads, in particular to a road surface with good water permeability. Background Art

[0002] Municipal roads are the main transportation roads in the city, connecting various areas of the city and providing services for residents and transportation. These roads are usually planned, built and maintained by the government or municipal authorities. Municipal roads play an important role in urban development. They are not only the infrastructure for transportation, but also an important carrier of urban life and social activities. They have a significant impact on the development, prosperity and quality of life of residents in the city.

[0003] When existing municipal roads are hit by rainy weather, most of the water is drained through drainage channels, but the residual water on the road surface cannot be discharged, making the road surface susceptible to erosion and damage after long-term use.

[0004] Therefore, the utility model provides a pavement with good water permeability to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a pavement with good permeability, which improves the effective permeability efficiency of the pavement body when it is eroded by rainwater, and facilitates the discharge of moisture to prevent long-term retention and damage to the pavement body.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pavement with good water permeability, comprising a pavement body, a plurality of connecting pipes are provided through the lower sides of the pavement body, and a plurality of water permeable holes are evenly opened on the upper end surface of the pavement body;

[0007] The pavement body comprises a roadbed, a water delivery layer is fixedly arranged on the upper end of the roadbed, a water permeable layer is fixedly arranged on the upper end of the water delivery layer, and a foundation layer is fixedly arranged on the lower end of the roadbed;

[0008] The water-permeable layer comprises a water-permeable coating layer, a water-permeable surface layer is fixedly arranged at the lower end of the water-permeable coating layer, a water-permeable subbase layer is fixedly arranged at the lower end of the water-permeable surface layer, and a drainage layer is fixedly arranged at the lower end of the water-permeable subbase layer;

[0009] The water delivery layer includes a filter layer, an anti-permeability layer, a water delivery pipe and a plurality of water storage pits. A plurality of diversion pipes are provided through the lower end of the water delivery pipe, and absorbent cotton is fixedly provided inside the plurality of diversion pipes.

[0010] Through the above technical solution, the water-permeable holes arranged on the upper end surface of the pavement body facilitate the penetration of water into the pavement body when it is eroded by rainwater, and the connecting pipes arranged on both sides of the pavement body facilitate the connection with the sewer pipe to extract the water inside the pavement body;

[0011] The water-permeable layer is set in the pavement body, and the water-permeable coating in the water-permeable layer is used to enhance the water permeability of the pavement, and provide additional wear resistance and skid resistance. The water-permeable efficiency is improved by the water-permeable surface layer and the water-permeable subbase layer, while providing a certain support to the pavement body. The water source is conveniently discharged through the drainage layer, ensuring effective water penetration and drainage.

[0012] The impurity particles in the water are filtered through the filter layer arranged in the water delivery layer, and the water flows into the water storage pit above the anti-seepage layer. The absorbent cotton in the diversion pipe at the lower end of the water delivery pipe is pumped into the water storage pit through an external water pump to discharge the infiltrated water. The accumulated water can be quickly removed, reducing the damage to the road surface caused by the accumulated water, so as to improve the utilization efficiency of water resources and the health of the ecosystem.

[0013] Furthermore, the material used for the road base layer is crushed stone concrete, and the material used for the foundation layer is roadbed soil;

[0015] Furthermore, the material used for the water-permeable coating is water-permeable ceramsite, and the material used for the water-permeable surface layer is water-permeable asphalt;

[0016] Through the above technical solution, permeable expanded clay can allow rainwater to pass through the surface, reduce surface water accumulation, improve the drainage performance of the pavement itself, and provide additional wear resistance and skid resistance. Permeable asphalt has the effect of improving drainage and reducing the impact of urban rainwater runoff on the environment.

[0017] Furthermore, the material used for the permeable base layer is cement concrete, and the material used for the drainage layer is gravel;

[0018] Through the above technical solution, cement concrete is used to support and protect the surface of the road surface and ensure that water quickly penetrates to the bottom. Gravel has large particle gaps, which can effectively promote the rapid drainage of water and keep the road surface dry and stable.

[0019] Further, the material used for the filter layer is a fabric filter material, and the material used for the anti-permeability layer is a concrete sealant;

[0020] Through the above technical solution, the fabric filter material has good filtering performance and tensile strength. It can prevent particles from entering the surface of the road surface, while allowing moisture to penetrate freely, playing a role of filtering and isolation. The concrete sealant can form a waterproof film to prevent moisture from penetrating into the interior of the road surface.

[0021] Furthermore, the water delivery pipe is arranged through the anti-permeability layer, and the absorbent cotton is squeezed on the bottom surface of the water storage pit;

[0022] Through the above technical solution, the water pipe is penetrated through the anti-permeability layer, so that the absorbent cotton can absorb water in the water storage pit into the water pipe for discharge.

[0023] Furthermore, a plurality of connecting pipes are provided with connecting flanges fixedly sleeved at their ends;

[0024] Through the above technical solution, the connection flange is arranged at the end of the connecting pipe, so that the sewer pipe can be connected conveniently.

[0038] The water supply layer 102 includes a filter layer 10201, an anti-permeation layer 10202, a water supply pipe 10203 and multiple water storage pits 10206. Multiple branch pipes 10205 are installed through the lower end of the water supply pipe 10203. Water-absorbing cotton 10204 is fixed inside the multiple branch pipes 10205. The impurity particles in the water are filtered by the filter layer 10201 arranged in the water supply layer 102, and the water flows into the water storage pit 10206 above the anti-permeation layer 10202. The water-absorbing cotton 10204 in the branch pipe 10205 at the lower end of the water supply pipe 10203 is pumped into the water storage pit 10206 by an external water pump to discharge the infiltrated water. The accumulated water can be quickly discharged, reducing the damage of the accumulated water to the pavement body 1, so as to improve the utilization efficiency of water resources and the health of the ecosystem.
