Description

Technical Field

[0001] The utility model relates to a manhole cover, in particular to an anti-sinking manhole cover, belonging to the technical field of manhole covers. Background Art

[0002] Most of the manhole covers in China are traditional metal round manhole covers. When the manhole covers are used for many years and are repeatedly crushed by buses and large engineering vehicles, uneven settlement will occur around them, which is not conducive to the flatness of the road surface. As a result, there will be a lot of water accumulation around the traditional manhole covers, and the drainage effect cannot be achieved. The manhole covers are often removed for maintenance, which will cause danger to pedestrians at night and hinder traffic during maintenance.

[0003] After searching, a Chinese patent with publication number CN210621769U discloses an anti-sinking manhole cover base, which involves the field of infrastructure technology and solves the technical problem that the manhole cover base is easily deformed and damaged. A vertical plate arranged around the edge of the cover plate is arranged on the lower surface of the cover plate and away from the manhole cover installation collar. A number of supporting ribs are arranged between the cover plate and the vertical plate. A plurality of first through grooves for injecting cement are arranged on the cover plate. The utility model has the advantage of extending the service life of the manhole cover base.

For this reason, we provide an anti-subsidence manhole cover to solve the above problems. Utility Model Content
