Anti-falling device for pavement manhole cover

Abstract

The invention relates to the technical field of roadbed construction, and discloses an anti-falling device for a pavement manhole cover. The anti-falling device for the pavement manhole cover comprises a cover plate, wherein a fixing block is movably connected to the left side of the cover plate; a water filtering groove is formed in the inner part of the cover plate; a fixing hole is formed in the inner part of the fixing block; a well seat is movably connected to the lower part of the fixing hole; a drainage groove is formed in the inner part of the well seat; a limiting block is movably connected to the outer part of the well seat; a limiting groove is formed in the right side of the limiting block; a movable groove is formed in the outer part of the limiting groove; and a roadbed is movably connected to the outer part of the cover plate. According to the anti-falling device for the pavement manhole cover, the well seat can play a role of secondary protection; when the cover plate is removed, the well cover still can be prevented from falling; when underground facilities are repaired, the drainage groove formed in the well cover is connected with the outside, so that air circulation is convenient, the limiting block is matched with the limiting groove, the well seat can be fixed, the operation is convenient, and the safety is high.

Description

technical field [0001] The invention relates to the technical field of roadbed construction, in particular to an anti-falling device for a road surface manhole cover. Background technique [0002] The roadbed is an important engineering structure of the road. It is laid on the surface of the roadbed. The manhole cover is the entrance and exit from the roadbed to the low facilities. With the rapid development of my country's economy, our infrastructure construction is becoming more and more comprehensive. And roadbed construction is playing an increasingly important role. [0003] Manhole covers slowly permeate our daily life, but there is also a great potential safety hazard in manhole covers. Passers-by are often dropped and injured due to opening the manhole cover for maintenance or when the manhole cover is not firmly fixed in life, endangering Life, in the absence of street lights, is also a great danger to passing cars. Often the wheels sink, causing the car to roll ove...
