Problems solved by technology

[0003] The existing inspection well includes a base, a well shaft, and a well cover. There are pipe connection holes on the shaft. Changing the height of the base due to the thickness of the cushion, or prefabricating a wellbore with a pipe connection hole of a suitable height, all make the installation of the inspection well more cumbersome
[0004] The above existing technical solutions have the following defects: when the deviation of the pipeline does not correspond to the connection hole of the pipeline, the deviation is not easy to adjust, which makes the installation of the inspection well slower

Abstract

The invention relates to a prefabricated inspection well, and belongs to the technical field of inspection wells. The prefabricated inspection well comprises a base, a wellbore, a closing-up section and a well lid. A pipeline connecting hole is formed in the wellbore, a supporting ring is slidably connected into the base, the wellbore is slidably connected into the base, the bottom end of the wellbore abuts against the top end of the supporting ring, a supporting assembly is arranged at the bottom of the supporting ring, and the supporting assembly includes a lifting drive member and a cushion block. The prefabricated inspection well has the effect of being convenient to install.

Description

technical field [0001] The invention relates to the technical field of inspection wells, in particular to a prefabricated inspection well. Background technique [0002] At present, the inspection well is for the maintenance of power supply, water supply, drainage, sewage discharge, communication, cable TV, gas pipe, street lamp line, etc. of urban underground infrastructure, and is conveniently installed. It is generally installed at the intersection of pipelines, turning places, pipe diameter or slope changes, and at certain distances on straight pipe sections, which is convenient for regular inspection of ancillary structures. [0003] The existing inspection well includes a base, a well shaft, and a well cover. There are pipe connection holes on the shaft. Depending on the thickness of the cushion layer to change the height of the base, or prefabricating a wellbore with a pipe connection hole of a suitable height, the installation of the inspection well is cumbersome. ...
