Inspection well anti-falling device

Abstract

The invention discloses an inspection well anti-falling device. The inspection well anti-falling device comprises an annular supporting structure and an anti-falling disc, wherein the annular supporting structure is formed by surrounding by at least two arc-shaped supporting sections and is used for being fixedly mounted on the inner wall of an inspection well, and the anti-falling disc is detachably mounted in the annular supporting structure. The inspection well anti-falling device has the beneficial effects that the inspection well anti-falling device can be mounted in the inspection well with the inclined hole wall, mounting is convenient and firm, the anti-falling support performance is far higher than that of similar products, the service life is long, and the maintenance cost of theinspection well is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of wellhead anti-falling devices, and in particular relates to an inspection well anti-falling device. Background technique [0002] In the construction of urban infrastructure, power supply, water supply, drainage, sewage, communication, cable TV, gas pipes, street lamp lines, etc. are generally arranged in the low pipe network. In order to facilitate the installation and maintenance of these underground Build inspection wells at certain distances, at pipeline intersections, at bends, at pipe diameter or gradient changes. [0003] In recent years, accidents of pedestrians falling into inspection wells due to slipping often occur. More and more attention has been paid to the installation of anti-falling devices at the wellhead of inspection wells. In the existing technology, the most common method is to install anti-falling devices directly at the wellhead Due to the large mesh opening of the anti-fall net,...

Problems solved by technology

[0003] In recent years, accidents of pedestrians falling into inspection wells due to slipping often occur. More and more attention has been paid to the installation of anti-falling devices at the wellhead of inspection wells. In the existing technology, the most common method is to install anti-falling devices directly at the wellhead Due to the large mesh opening of the anti-fall net, not only cannot prevent bricks, stones and other sundries from falling in, but also the anti-fall net will age and its support strength will decrease as time goes by, so it may not be able to completely bear the fall of the human body. weight, there is a greater safety hazard
