Description

A kind of pipeline well production template and method based on factory production pipeline well

technical field

The invention belongs to the field of municipal construction, and relates to a template for making a pipeline well, in particular to a template for making a pipeline well produced in a factory and a method for making a pipeline well based on it.

Background technique

The pipeline used in the drainage project of a municipal supporting project is de315 UPVC. The total length of the solid wall pipe is 1224 meters. The inspection well is a square well, of which there are 109 with a specification of 600×600mm and 4 with a specification of 1000×1000mm. The well wall is thick 15cm, well depth 85-100cm. The traditional inspection well in the municipality is built with 85 bricks. Due to its poor sealing, water seepage problems also follow, which directly affects the construction quality of municipal engineering. However, the customer's design required that the pipe well be poured with concrete cast-in-place, and the project department had no similar construction experience. Now according to the construction quality of the A-section concrete pipe wells completed in this project, a total of 400 points were randomly checked, of which 67 were unqualified, with a pass rate of 83.25%, and the main reason for the unqualified pipe wells was "Poor smoothness of wellbore" and "deformation of wellbore geometry". The most important thing is that the existing pipeline well needs to be constructed on the site of the supporting project, which takes up a lot of space and has low production efficiency. It also needs to provide sufficient concrete solidification time and curing time, which greatly delays the progress of the project. At the same time, in order to improve the pipeline well In view of the reason of "shaft geometric deformation", it is necessary to design a production formwork that can produce pipeline wells in a factory and prevent its geometric deformation.
