Abstract

The invention relates to a construction method for a jacking structure of a pipe jacking work well. The construction method mainly comprises the construction steps of 1 cushion layer and back base wall constructing; 2 rail installing; 3 jack installing; 4 hole water stopping system installing; 5 pipe joint and jacking iron hoisting. The construction method has the advantages that disassembly and assembly are convenient, the construction efficiency is high, friction between a rail and a pipe joint can be reduced, auxiliary guide positioning can be supplied to the pipe joint and has the better economic and technical benefit.

Description

technical field [0001] The invention relates to a jacking structure of a pipe jacking well, in particular to a construction method of the jacking structure of a pipe jacking well. technical background [0002] With the development of urban construction, the underground space trenchless technology has attracted more and more attention and has been widely used. How to install and replace urban water supply and drainage, gas and communication facilities under the premise of minimal damage to the urban environment has put forward new requirements for underground engineering construction technology. [0003] The pipe jacking technology is to use the hydraulic cylinder to jack the pipe jacking machine and the pipe joints to be laid underground one by one from the pipe jacking working well without excavating the surface, until the trenchless underground pipeline laying of the pipe jacking receiving well. construction process. At present, in the pipe jacking construction, on the o...
