Assembly type anti-subsidence well lid

Abstract

The invention discloses structure construction of an assembly type anti-subsidence well lid product. Through the assembly type anti-subsidence well lid, subsidence and collapse of inspection well foundations can be resisted and eliminated, and the phenomena of cracking and damage of the pavement around the well lid are prevented and reduced. The assembly type anti-subsidence well lid has wide application prospects in the fields of municipal newly-built road engineering and municipal current situation road inspection well reconstruction engineering. Due to the fact that the unique design concept and idea that a solid integral well ring is formed on an inspection well lid support, a reinforcement cage and poured C30 concrete and the stress distribution mode of original inspection well foundations, a well lid support and connected pavement subgrade is structurally changed are adopted for the structure construction of the assembly type anti-subsidence well lid product, when external force acts, through stress redistribution and stress transfer, uneven settlement and collapse are avoided, and the purposes that well lid subsidence and cracking of the pavement around the well lid are prevented are achieved. The structure construction of the assembly type anti-subsidence well lid product is not only suitable for municipal newly-built road engineering but also suitable for municipal current situation road inspection well reconstruction engineering.

Description

technical field [0001] The invention relates to the field of municipal road inspection well cover support, steel bar processing and installation and construction. It is an assembled anti-sinking manhole cover product specially invented to solve the subsidence and collapse of the road inspection well foundation and prevent the cracking and damage of asphalt concrete around the manhole cover. . Background technique [0002] In the existing inspection well construction technology and structural structure, the common practice is: first place the standard manhole cover and support on the foundation of the masonry well shaft according to the design requirements, or on the factory prefabricated concrete well shaft, and adjust the distance between the manhole cover and the road surface. After leveling the height, pour C30 concrete to fix it. The disadvantages of this method are: (1) the foundation of the inspection well sinks and collapses seriously, which affects driving and poses...

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: (1) the foundation of the inspection well sinks and collapses seriously, which affects driving and poses a great safety hazard; (2) the road surface around the inspection well cover is cracked and damaged, which reduces the service life of the road and affects the appearance; (3) ) Not only the daily maintenance and repair costs are high, but also the roads are often closed for construction, which makes the already congested urban traffic worse
