Unitary piping inspection well

Abstract

An unitary manhole has a vertical hollow shaft. An opening, at least, is arranged on its wall to connect with main channel. The shaft body, which has a telescopic structure, is above the horizontal channel body, which has an opening and a tunnel for connecting with the vertical shaft. A manhole cover is on the top of the vertical shaft. The manhole can be industrially produced, installed easily, and can meet various demands to connect tightly with channels in different angles, with short installation period and without secondary pollution.

Description

technical field [0001] The present invention relates to the field of pipeline fittings, in particular to inspection wells in large pipeline systems. Background technique [0002] Inspection wells in underground pipeline systems are also called pipeline wells and manholes. At present, inspection wells for large underground pipelines such as sewers, industrial and mining sewage discharge pipelines, underground communication, cable installation pipelines, etc., especially for manholes in sewer pipelines, most of which are used bricks (or cement) under the ground in pipeline passages. Build a well body to the ground, then cover it with a well cover, and open an opening on the side of the well body for pipeline connection; the problem is that the construction period is long, it is easy to produce shrubs and weeds, and it is difficult to dredge the water flow. In addition, there is serious leakage at the connection between the pipeline and the well body (especially the connection...

AI Technical Summary

Problems solved by technology

At present, large-scale underground pipelines are inspection wells such as sewers, industrial and mining sewage discharge pipelines, underground communications, cable placement pipelines, etc., especially for inspection wells in sewer pipelines. Build a well body to the ground, and then cover it with a well cover, and open an opening on the side of the well body for pipeline connection; the existing problems are that the construction period is long, it is easy to produce shrubs and weeds, it is inconvenient to dredge, and the water flow is not smooth. Moreover, there is serious leakage at the connection between the pipeline and the well body (especially the connection between the traditional cement well and the plastic pipe), which will lead to secondary pollution of the surrounding environment

There are also prefabricated cement wells. Although it can shorten the pipeline construction period, it still has the above-mentioned other problems. Moreover, when it is in the pipeline and connected with the pipeline, because its height cannot be adjusted, the well cover on the cover is generally not level with the ground
