Description

Technical Field

[0001] The utility model relates to the technical field of roadbed anti-settlement, in particular to a municipal roadbed anti-settlement device. Background Art

[0002] The anti-subsidence device is a device used to prevent the subsidence of municipal road subsidence. When using the anti-subsidence device, the subsidence piles are directly inserted into the interior of the subsidence, and then the road surface is paved on the surface of the subsidence. Then, when the vehicle is driving on the road, the surface road surface subsidence can be well prevented, thereby avoiding affecting driving safety.

[0003] According to the description of a disclosed municipal roadbed anti-subsidence device (authorization announcement number: CN219033469U), "a municipal roadbed anti-subsidence device includes a water collecting tank, a water inlet pipe, a diversion pipe and an elastic support assembly. The water collecting tank is arranged in the roadbed layer, the water inlet end of the water inlet pipe is connected and arranged on the road surface, and the water outlet end is connected and arranged in the water collecting tank; the water inlet end of the diversion pipe is connected and arranged in the water collecting tank, and the water outlet end is connected to the external drainage network; the elastic support assembly is arranged under the roadbed layer and is used to provide elastic support for the roadbed layer. The accumulated water on the road surface flows into the water collecting tank through the water inlet pipe, and the water in the roadbed layer flows into the water collecting tank, and then the water in the water collecting tank is drained away through the diversion pipe, thereby improving the problem of long-term rainwater infiltration and erosion on the road surface and roadbed layer; and the elastic support assembly provides elastic support for the roadbed layer, thereby improving the problem of long-term uneven load of the roadbed layer on the vehicle, and effectively improving the problem of roadbed settlement causing the road surface to be rugged and uneven, thereby affecting driving safety."

[0004] Existing municipal roadbed anti-settlement devices use springs to provide elastic support for the roadbed. However, the springs have a limited service life. When the springs are overloaded, they can no longer support the roadbed. Furthermore, the piles cannot be fixed to the ground at both ends. Therefore, an improved municipal roadbed anti-settlement device is needed to address these issues. Utility Model Content
