Technical Field

[0001] The invention relates to the field of municipal equipment, in particular to a municipal road manhole cover backfilling and leveling device. Background Art

[0002] Manhole covers on municipal roads are an indispensable part of municipal facilities. They are mainly used to cover various facilities under the road, such as drainage pipes, cables, communication lines, etc. They can not only protect these facilities from damage, but also prevent pedestrians and vehicles from accidentally falling into or getting injured. Municipal departments need to regularly inspect and maintain the road surface to ensure the flatness and stability of the road surface, thereby extending the service life of the manhole cover and improving its safety.

[0003] When backfilling the manhole cover, it is necessary to dig a concentric pit on the upper part of the shaft, and pour cement at the bottom of the pit and level it to facilitate the installation of the manhole cover. The existing leveling device uses a rotating scraper for leveling, but when in use, it can only smooth the poured cement, which is not convenient for corresponding adjustments according to the thickness of the manhole cover.
