Description

Assembly structure of inspection well

Technical Field

The application relates to the field of underground drainage pipes, in particular to an assembly structure of an inspection well.

Background

The inspection well is used for maintaining power supply, water drainage, pollution discharge, communication cable television, gas pipes, street lamp lines and the like of urban underground infrastructure, and is convenient to install. It is usually installed at the intersection of pipelines, turning, where the pipe diameter or slope changes, and at certain intervals on straight pipeline sections, and is convenient for regular inspection of the attached structures.

A common inspection well for drainage type comprises a vertically arranged well body and drainage pipes which are arranged on the peripheral surface of the well body and are communicated with the inside of the well body. The periphery of the well body is provided with a water through hole, the conventional connection mode of the well body and the drain pipe is that a socket of the drain pipe is inserted into the water through hole of the well body, then the connection position of the drain pipe and the water through hole is subjected to water closing treatment, and the water closing treatment is mainly to coat cement mortar on a gap between the drain pipe and the inner wall of the water through hole for plugging, so that the drain pipe and the well body are connected and fixed.

After the inspection well is used for a long time, the connecting gap of the drain pipe and the well body is often washed away by a water source, and when the water pressure in the well body is large, the acting force along the extending direction of the drain pipe can be applied to the connecting gap of the drain pipe and the well body, so that the cement mortar is easily broken and separated, and the water leakage is caused. The water source leaks around the well body and contacts with the soil layer, so that the soil layer is easy to sink, and the ground around the inspection well is easy to collapse.
