Abstract

The invention relates to a check well ring base at the middle of road, which can reduce the non-uniform surface sink between the well structure and around soil, to cause the damage of around road. Wherein, said invention is an annular element whose rigidity is larger than around soil; its profile of radial wheel is larger than the profile of radial wheel of well wall; the outer side of lower surface is the lower support surface combined with around soil; the inner side of lower surface is molded into one groove; therefore, the well wall that embed into the groove can slide along the axis of well wall. The invention also provides a check well of said well ring base and relative construction.

Description

technical field

[0001] The invention relates to an inspection well ring mouth seat and an inspection well with the well ring mouth seat and its construction method. Specifically, the invention proposes an improved technical scheme for the well ring mouth seats of various wells in the middle of the road . Background technique

[0002] Various inspection shafts in the middle of the road are often crushed by passing vehicles. However, the usual well wall and the well ring seat arranged at the upper end of the well wall all adopt substantially the same inner and outer diameters, so that between the well structure and the surrounding soil layers, except for mutual friction In addition to the force, it is basically a force system that has nothing to do with each other.

[0003] Judging from the materials used in the well body structure, the well body structure has different rigidity from the surrounding soil layer. Therefore, in theoretical research, the well structure is often...
