Pipe fitting type examination well

Abstract

Disclosed is a pipe fitting type examination well, which comprises a hollow well member, which is connected with a main flow passage, a well member pipe socket is arranged above the well member, a coupling pipe is arranged on the internal walls near the well member pipe socket, a telescopic pipe is arranged on the medial wall of the coupling pipe, the main flow passage tube is on the bottom of the well member. The invention can realize easy pipe line construction.

Description

technical field [0001] The 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 inspection wells. 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 an...

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
