Technical Field

[0001] This utility model relates to a municipal manhole cover, specifically a municipal road manhole cover device for preventing settlement, and belongs to the field of municipal manhole cover technology. Background Technology

[0002] Manhole covers are enclosures leading to underground facilities and are widely used in public utilities such as water supply, telecommunications, electricity, gas, heating, fire protection, and sanitation. With my country's rapid economic development, the demand for infrastructure construction has driven the continuous expansion of the manhole cover market. Manhole cover standards, as a system regulating the load-bearing capacity and technical requirements of manhole covers for underground facilities, cover indicators such as materials, load performance, and usage scenarios. Manhole cover settlement refers to the phenomenon where the manhole cover sinks below or significantly below the road surface level, causing uneven road surfaces. Settled manhole covers make the road surface uneven, causing vehicles to bounce and jolt when passing over them, affecting the driving experience and potentially leading to accidents such as loss of control and tire blowouts. Pedestrians are also more likely to trip and fall, causing personal injury.

[0003] Chinese Patent Publication No. CN109440829A discloses an anti-settlement cable manhole cover, including a frame and a cover. The frame includes a body and a flange. The body includes a mounting base and a socket. The flange includes a horizontal pressure-bearing section and an inclined section. The body is provided with a rubber strip to reduce vibration between the frame and the cover. The advantages of this invention are: by setting the frame in a structure of body and flange, the body and the road surface structure layer are integrated by the flange, making the entire manhole cover an integral part of the road surface. This can directly distribute the load to the road surface structure layer, protect the asphalt pavement around the manhole cover, and prevent settlement.

[0004] However, the inventor of the above-mentioned device believes that it has certain defects. The above-mentioned device uses the method of reinforcing the manhole cover, thereby prolonging the settlement time of the manhole cover. After a long time, the manhole cover will still settle, and it is not convenient to adjust it after settling. Therefore, this utility model provides a municipal road manhole cover device for preventing settlement. Utility Model Content
