Elastic component, maintenance-free municipal well and its construction and maintenance methods

Abstract

The invention relates to an elastic component, a maintenance-free municipal well and a construction and maintenance method. The municipal well comprises an upper well section, a plurality of middle well sections, a lower well section and an elastic component which are independent, the elastic component is arranged between the upper well section and the middle well section or / and between the middle well section and the lower well section, and an outer bulge of a second connecting structure of the elastic component is supported on a surrounding roadbed of a shaft. The elastic component comprises a first connecting structure, an elastic structure, a second connecting structure and a limit member, wherein the elastic structure is located in a cavity formed by overlapping the first connecting structure and the second connecting structure, and a limit piece ring sleeves the elastic structure to limit the deformation of the elastic structure. The second connecting structure is embedded into the surrounding roadbed structure of the well, so as to enhance the connection between the municipal well and the surrounding roadbed structure, and realize that the rigidity of the municipal well is matched with that of the surrounding roadbed.

Description

technical field [0001] The invention relates to the technical field of municipal engineering, in particular to a structure, construction method and maintenance method of a municipal well in municipal engineering. Background technique [0002] In urban roads, there are many types of municipal facilities (inspection facilities, rainwater facilities, etc.). In the long-term use of the road, it is very common for the uneven settlement phenomenon of the municipal and surrounding subgrades to occur. The subgrade is a relatively flexible structure. After completion, due to the action of live loads such as vehicles and the self-weight of the subgrade, some subsidence will often occur on the subgrade, while the municipal subgrade is generally a rigid structure of masonry structure or concrete structure. The existing The structure of the municipal well is an overall structure with a small top and a large bottom in the shape of "eight". This structure is not conducive to load reductio...

Problems solved by technology

[0005] One of the purposes of the present invention is to provide an elastic component and a maintenance-free municipal well. The technical problem to be solved is that the existing rigid municipal well cannot cooperate with the roadbed to deform, resulting in deformation of the municipal well and its surroundings due to the action of external loads Differences create disruptive technical issues
