Well lid support, inner well lid of inspection well and well lid component of inspection well

Abstract

The invention provides a well lid support, an inner well lid of an inspection well, and a well lid component including the well lid support and the inner well lid of the inspection well. The well lid component of the inspection well further comprises an outer well lid, wherein the inner well lid is detachably mounted on a lug boss of a well lid support main body through matching between gaps on the outer edge of the inner well lid and clamping strips on the well lid support main body; the outer well lid is mounted in the upper opening of the well lid support and can move out of the upper opening; the inner well lid is positioned below the outer well lid. The well lid support provided by the invention can be equipped with the inner well lid, which can prevent a passerby from falling into a well once the outer well lid is cracked, displaced or stolen; and as the inner well lid is stopped by the clamping strips on the well lid support main body, the inner well lid can be prevented from floating and moving away due to excessive pressure of water accumulated in the well.

Description

technical field [0001] The invention relates to an inspection well cover assembly, in particular to an inspection well cover assembly including an anti-falling device. Background technique [0002] At present, with the rapid development of urban road construction in my country, the maintenance and repair of urban roads is becoming more and more important. Urban road landscape, driving safety and environmental lighting also directly reflect the appearance of urban construction. Over the years, problems such as the overall subsidence of the manhole cover support and the cracking around the manhole cover (rotten eye circle phenomenon) have existed to varying degrees in municipal road projects, and the cast iron manhole cover is also easy to be stolen to form a "trap". [0003] In the above-mentioned situations, not only the smooth passage of vehicles is affected, but also the tragedies of personal injury accidents caused by manhole cover rupture, displacement or theft are often...

AI Technical Summary

Problems solved by technology

Over the years, problems such as the overall subsidence of the inspection well cover support and the cracking around the manhole cover (rotten eye circle phenomenon) have existed to varying degrees in municipal road projects, and the cast iron manhole cover is also easy to be stolen to form a "trap"

[0003] In the above-mentioned situations, not only the smooth passage of vehicles is affected, but also the tragedies of personal injury accidents caused by manhole cover rupture, displacement or theft are often reported. However, due to the influence of economic costs, social environment and other factors, currently commonly used Manhole covers have the risk of being broken, shifted or stolen, so it is necessary to have an inspection manhole cover device that can effectively prevent personal injury and vehicle damage accidents after the manhole cover is stolen, displaced or broken.
