Description

Technical Field

[0001] The present application relates to the field of municipal manhole covers, and in particular to a road surface structure with a manhole cover having high stability. Background Art

[0002] There are many underground pipelines in urban construction. Every section of the pipeline must have an outlet to the ground. The section from the pipeline to the ground is called a manhole. The manhole opening is usually flush with the ground, so a manhole cover is needed to cover the manhole opening. The road surface at the edge of the common manhole cover on the road surface will be damaged or loose after a period of use, which will cause unstable driving of vehicles. In the long run, it will affect the stability of the manhole cover and cause the manhole cover to sink, which has certain safety hazards. Therefore, the road surface around the manhole cover needs to be repaired every once in a while, which is troublesome and needs to be improved. Utility Model Content
