Description

Technical Field

[0001] The present application relates to the technical field of manhole covers, and specifically to a manhole cover for municipal engineering. Background Art

[0002] Manhole covers are used to cover deep wells on roads or in homes to prevent people or objects from falling. According to the material, they can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. They are generally round in shape. They can be used in green belts, sidewalks, motorway lanes, docks and alleys, etc.

[0003] In modern cities, when encountering heavy rain, water is easy to accumulate on the road. In order to drain the rainwater on the road as soon as possible, people often open the manhole covers on the road and place them on the roadside to speed up the dredging of the accumulated water. If all the manhole covers are opened and parallel to the ground, pedestrians are likely to fall through the manholes. If the manhole covers are not opened, the accumulated water cannot be discharged quickly.
