[0002] A manhole cover is a cover used to cover deep wells on roads or in homes. Its main function is to prevent people or objects from falling. It also protects underground pipes, equipment, passages and other facilities. Many sewer manhole covers are needed in urban drainage systems, and rainwater is collected on pedestrian roads on rainy days to reduce urban waterlogging.

[0003] The utility model patent with patent application number 201721117850.5 discloses a reinforced manhole cover, which includes a cover body, a drain hole and a seat ring. The cover body is provided with a drain hole, the cover body cooperates with the seat ring, the bottom end of the seat ring is movably connected to one end of a circular frame, a fixing rod is provided at the other end of the circular frame, and a hook for hanging the fixing rod is provided at the bottom end of the cover body. The circular frame is composed of a criss-cross metal rod body welded in a metal ring, and a buffer layer is fixedly connected to the lower end face of the cover body, and the buffer layer is fitted with the circular frame; the circular frame at the bottom serves as a support for the manhole cover to prevent the manhole cover from being lost or dislocated, which may cause personal injury.

[0004] According to the above structure, it can be seen that the current manhole cover is easily misplaced or sunken due to the squeezing of pedestrians and vehicles when in use, thereby forming a height difference between the pedestrian road and making it easy for pedestrians to trip, posing a safety hazard. For this reason, we propose a reinforced manhole cover structure. Utility Model Content
