Constituent component of inspection well body

Abstract

The invention discloses a constituent component of an inspection well body, which is formed by integral injection molding and comprises a main body part and a stair. The main body part comprises an upper end opening, a lower end opening and a spherical side wall, wherein the spherical side wall is provided with a first reinforcing convex part, a second reinforcing convex part and a reinforcing rib; the upper end opening is provided with a clamping bump and a clamping groove; the first reinforcing convex part is arranged at the inner side of the spherical side wall; the second reinforcing convex part is arranged at the outer side of the spherical side wall and extends from the upper end opening to the middle position of the main body part to form smooth transition; the reinforcing rib is arranged at a concave part of the outer side of the first reinforcing convex part; and the lower end opening is provided with a butt-joint lump and a butt-joint groove. The constituent component of the inspection well body has the following benefits: the height of the inspection well body can be adjusted; the service life of the constituent component of the inspection well body is prolonged; and universalization is enhanced, the construction is convenient, the airtightness is good, and the oxidation-corrosion resistance is excellent.

Description

technical field [0001] The invention relates to an underground drainage and sewage inspection well component for municipal engineering, in particular to an inspection well body component with high versatility, convenient construction, good sealing performance, good oxidation and corrosion resistance, and convenient use. Background technique [0002] Existing underground network pipe inspection wells for municipal engineering are mostly brick concrete inspection wells, which mainly have the following disadvantages: [0003] First of all, the height cannot be changed at will, and users can only use a fixed height, which greatly increases the difficulty of construction and cannot guarantee the quality of the project; [0004] Secondly, the strength is low, and the support strength of the brick structure is low, especially the variable diameter and shrinkage part of the brick structure close to the road surface is easy to collapse due to the impact of unbalanced lateral force; s...

AI Technical Summary

Problems solved by technology

[0003] First of all, the height cannot be changed at will, and users can only use a fixed height, which greatly increases the difficulty of construction and cannot guarantee the quality of the project;

[0004] Secondly, the strength is low, and the support strength of the brick structure is low, especially the variable diameter and shrinkage part of the brick structure close to the road surface is easy to collapse due to the impact of unbalanced lateral force; secondly, the construction period of the well body is long and the construction is complicated. Stacking has high requirements for civil engineering, poor standardization, generalization, and serialization, and the amount of manual work and materials used are important factors affecting quality; in addition, there are defects such as non-replaceable, easy to break, and pollution caused by leakage, requiring frequent maintenance

[0005] Thirdly, most of the ladders that need to be inspected are made of brick-built concrete inspection wells piled with fixed steel bars. Because the brick-built concrete is not corrosion-resistant, the ladders become loose, which will endanger the personal safety of the inspectors, and then the inspectors will carry the ladders to go down the well for inspection. , resulting in increased workload
