Description

Technical Field

[0001] The present invention relates to the technical field of manhole covers, and in particular to an anti-jumping reinforced manhole cover. Background Art

[0002] Manhole covers are an indispensable part of urban infrastructure and are widely used at the entrances and exits of various underground facilities. Their main function is to cover and protect underground pipes, cables, drainage systems, etc., while ensuring the safe passage of pedestrians and vehicles. Most of the existing manhole covers use five-proof manhole covers, namely anti-jump, anti-theft, anti-sound, anti-fall and anti-displacement. The anti-jump function is to make the manhole cover and the manhole ring more firmly contact by setting a retaining spring design to prevent the manhole cover from jumping up due to the vehicle passing by. The anti-theft function is achieved by hinge connection. The anti-sound function is achieved by setting a rubber ring. Anti-fall is achieved by setting an anti-fall net, and anti-displacement is reinforced by anchor bolts to prevent the manhole cover from displacement. In the prior art, the strength of the manhole cover is strengthened to prevent the deformation of the manhole cover and the occurrence of jumping. For example, the patent with announcement number CN21030327U discloses an anti-jump reinforced manhole cover.
