Description

Technical Field

[0001] The utility model relates to the technical field of municipal road structure design, and particularly relates to a municipal road anti-seepage structure. Background Art

[0002] Municipal roads reach all regions of the city and are used for urban transportation and pedestrians. Sidewalks higher than the road surface are set on both sides of the road. After long-term operation, the road surface of the municipal road is prone to damage, and rainwater will seep into the road through the defective positions, which easily leads to the instability of the internal support structure of the road, such as the occurrence of larger cracks or subsidence. Therefore, a municipal road must be provided with an anti-seepage structure to enhance the stability of the municipal road and extend its service life.

[0003] For example, CN 219157306 U discloses a municipal road anti-seepage structure, which includes a roadbed. A water-stable layer is arranged on the top of the roadbed, a concrete layer is arranged on the top of the water-stable layer, and a drainage component is arranged inside the water-stable layer. The drainage component includes a drain pipe, a cover plate and through holes. The drain pipe is fixedly connected inside the water-stable layer, the cover plate is fixedly connected to the top of the drain pipe, and through holes are arranged inside the cover plate. A waterproof plate is fixedly connected to the outside of the roadbed, an installation block is fixedly connected to the outside of the waterproof plate, a reinforcement plate is fixedly connected to the top of the waterproof plate, and fixing rods are arranged inside both the installation block and the reinforcement plate. This structure aims to prevent sections prone to water accumulation from being easily eroded by rainwater and losing strength, thereby ensuring the stability of the overall road structure. However, there are still the following problems: Each drainage component is arranged at intervals in the water-stable layer, and most of the rainwater still seeps towards the roadbed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a municipal road anti-seepage structure with reasonable structure and reliable use to solve the above problems, further reduce the penetration amount of rainwater into the roadbed, thereby further enhancing the stability of the municipal road and extending its service life.

[0005] The technical solution of the utility model is as follows:

[0006] A municipal road anti-seepage structure comprises a roadbed, a water-stabilizing layer arranged on the top surface of the roadbed, a concrete layer arranged on the top surface of the water-stabilizing layer, an asphalt layer arranged on the top surface of the concrete layer, and a plurality of drainage components arranged in the water-stabilizing layer at intervals along the length direction of the water-stabilizing layer. The technical key points are: the drainage component comprises a U-shaped drainage pipe, a cover plate arranged on the upper end of the U-shaped drainage pipe and having a drainage hole group, a support group arranged on the lower surface of the cover plate and the lower end of which is against the inner bottom surface of the U-shaped drainage pipe, and a positioning column group arranged at the bottom of the U-shaped drainage pipe; a positioning strip is arranged between the U-shaped drainage pipes of two adjacent drainage components, the top surface of the positioning strip is high in the middle and low on both sides, and the low end extends to the edge of the cover plate of the drainage component; a hydrophobic layer is arranged on the top surface of the positioning strip, and drainage grooves for communicating with the municipal drainage system are respectively arranged on both sides of the width direction of the roadbed, and both ends of the U-shaped drainage pipeline are connected to the drainage grooves.

[0007] In the above-mentioned municipal road anti-seepage structure, the bottom surface of the positioning strip is provided with a protrusion embedded in the water-stabilizing layer.

[0008] In the above-mentioned municipal road anti-seepage structure, the positioning strip is provided with reinforcing ribs extending along its length direction.

[0009] In the above-mentioned municipal road anti-seepage structure, the top surface of the positioning strip is provided with an anti-slip pit which is in close contact with the hydrophobic layer.

[0010] The beneficial effects of the utility model are:

[0011] By arranging a positioning strip between two drainage components and arranging a hydrophobic layer on the upper surface of the positioning strip, rainwater that seeps onto the hydrophobic layer moves from a high position to a low position along the hydrophobic layer, and finally converges to the cover plate of the drainage component, and is discharged into the U-shaped drainage pipe through the drainage hole group on the cover plate, and then discharged from both ends of the U-shaped drainage pipe into the drainage trough and merged into the municipal drainage system. Based on this, the utility model further reduces the amount of rainwater that penetrates into the roadbed, thereby further enhancing the stability of the municipal road and extending the service life of the municipal road.
