AI Technical Summary

Technical Problem

The traditional pipe header construction method has a long construction cycle in a small space, a large demand for work well space, high safety risks in hole breaking, and high construction costs in narrow receiving wells, which are serious waste of resources.

Method used

Using a split pipe hoisting machine, the pipe hoisting machine is split into multiple shields, and each shield is composed of the upper and lower shields arranged oppositely, and is lifted and assembled in steps, combined with the upper and lower shields, and installed in combination with the upper and lower push. Shorten the construction cycle, improve safety, and facilitate lifting and adjusting lifting posture in small receiving wells to avoid waste of resources.

Benefits of technology

It effectively shortens the construction cycle, improves construction safety, reduces resource waste, reduces construction costs, and avoids the situation where the pipe hoist shell remains in the tunnel.

Abstract

The invention provides a construction method of a pipe jacking machine in a narrow space, the pipe jacking machine comprises a split type pipe jacking machine composed of a plurality of shield bodies, and each shield body is formed by combining an upper shield body and a lower shield body which are oppositely arranged up and down. The split type pipe jacking machine is split into a plurality of units, hoisting work of the split type pipe jacking machine can be conveniently completed in a narrow space, meanwhile, through a pushing installation mode, installation and jacking construction can be combined, and therefore the construction period is effectively shortened, and the construction efficiency is improved. In addition, according to the method, the situation that in a traditional method, constructors conduct tunnel portal breaking construction operation in a crack between the tunnel portal and a pipe jacking machine is avoided, safety is effectively improved, after tunnel portal breaking is completed, the first shield body is jacked into the tunnel portal, beneficial support is formed, the collapse condition of the tunnel portal can be avoided, and in addition, the construction efficiency is improved. Due to the structure of the split type pipe jacking machine, the size of each part is smaller, the pipe jacking machine can be conveniently hoisted in a narrow receiving well, and the hoisting posture can be conveniently adjusted.
