Abstract

The invention provides a check ring combination for a road manhole and a steel support ring for installing the check ring combination, wherein the check ring combination for the road manhole comprises an upper check ring and a lower check ring, the upper check ring comprises an upper check ring body and an extension edge, the upper check ring body is in a cylinder structure, and the extension edge is connected with the lower end of the upper check ring body; the lower check ring comprises a first section of lower check ring in a cylinder structure, a second section of lower check ring in a cylinder structure and a third section of lower check ring in a cylinder structure, which are arranged vertically and sequentially, the second section of lower check ring is in a frustum-shaped cylinder structure, the lower end of the first section of lower check ring is connected with the big end of the second section of lower check ring, and the upper end of the third section of lower check ring is connected with the small end of the second section of lower check ring; and the extension edge is overlapped with the upper end of the first section of lower check ring. The influence of road settlement on the manhole can be avoided through the check ring combination for the road manhole and the steel support ring for installing the check ring combination.

Description

technical field [0001] The invention relates to a component of a road inspection well, in particular to a retaining ring combination used in the road inspection well, and also to a steel support ring used when installing the retaining ring combination. Background technique [0002] With the expansion of the road network and people's higher and higher requirements on the environment, more pipes and cables need to be buried underground, such as water supply and drainage pipes, communication cables, power transmission and distribution cables, etc., so it is used for laying and repairing these The construction volume of inspection wells for pipelines and cables is very large. In many cases, after the road is built, the road will settle due to geological or quality reasons, which will affect the position of the manhole cover and the manhole cover seat and the sealing between the two and the wellbore. Contents of the invention [0003] The object of the present invention is to ...
