Description

Technical Field

[0001] The present application relates to the field of road drainage, and in particular to an anti-seepage pavement structure. Background Art

[0002] Roads refer to highways, urban roads, and areas under the jurisdiction of a unit where motorized vehicles are permitted, including public plazas and public parking lots. Roads are essentially infrastructure for trackless vehicles and pedestrians. Based on their usage, they are categorized as highways, urban roads, rural roads, factory and mining roads, forestry roads, examination roads, competition roads, automobile test roads, workshop access roads, and school roads. The purpose of pavement drainage is to ensure that highways and urban roads at all levels are equipped with necessary drainage facilities based on local precipitation and road conditions. The spatial layout and structure of the pavement should be appropriately selected to promptly drain precipitation from the road surface, preventing accumulated water from seeping into the pavement and damaging the roadbed, thereby ensuring driving safety. Water on the asphalt pavement of high-grade roads with high traffic speeds should be quickly drained to prevent the formation of a water film on the asphalt pavement, which could affect driving safety.

[0003] In actual use, the existing road surface has poor drainage, which causes the accumulated water on the road surface to directly penetrate into the roadbed. Long-term penetration of the roadbed by accumulated water will directly cause the roadbed to be damaged, which will directly affect the service life of the road. Utility Model Content

[0004] In order to solve the problem of poor drainage of existing pavement causing accumulated water to seep into the roadbed, the present application provides an anti-seepage pavement structure.

The stability of the road surface is improved through the cooperation between the road base layer, the cushion layer and the asphalt concrete. The asphalt pavement has a structure that is high in the middle and low on both sides, which is convenient for drainage.

[0012] The top outer wall of the crushed stone base layer is paved with a filter layer, and the top outer wall of the filter layer is paved with a crushed stone layer, and the drainage pipe is embedded in the filter layer.

[0013] By adopting the above technical solution, the cooperation between the filter layer and the gravel layer makes it easy to filter the accumulated water, preventing impurities in the accumulated water from entering the drain pipe.

The outer wall of the filter pipe is provided with multiple openings distributed at equal distances, and the inner wall of the opening is fixedly connected to a filter screen.

[0015] By adopting the above technical solution, the setting of the drainage well facilitates the transfer of accumulated water, and the filter mesh on the filter tube facilitates filtering out impurities in the accumulated water, thereby preventing impurities from entering the filter tube. At the same time, the setting of the drainage well facilitates the temporary storage of filtered impurities.

[0016] The outer walls on both sides of the drainage well are fixedly connected with the same protective grid, the top outer wall of the drainage well is clamped with a well cover, and the top outer wall of the well cover is provided with a plurality of leakage holes distributed at equal distances.

[0017] By adopting the above technical solution, the accumulated water on the road surface can be conveniently drained out through the leakage holes on the manhole cover, and the setting of the protective grid makes it convenient to filter the accumulated water.

[0018] A sewer pipe is installed inside the soil base layer, and the sewer pipe is connected to the filter pipe through a pipeline.

[0019] By adopting the above technical solution, the accumulated water filtered by the filter mesh on the filter tube is directly discharged through the sewer pipe.
