Problems solved by technology

However, if the large-section rectangular pipeline is constructed by pipe jacking, the top distance is not too long, only about 100 meters, and it is very difficult to construct a rectangular large-section shield. The assembly process of pipe joints is complicated, the construction progress is slow, and the safety is not high.

Abstract

The invention discloses a rectangular-section pipe joint shield assembling method. The rectangular-section pipe joint shield assembling method comprises the steps of assembling of pipe joint assembling equipment, preparation before lower pipe joint installation, lower pipe joint transportation, lower pipe joint installation through the pipe joint assembling equipment, preparation before upper pipe joint installation, fixed rail laying, upper pipe joint transportation, upper pipe joint installation through the pipe joint assembling equipment, pipe joint assembling equipment propelling, and circulation of the steps except for assembling of the pipe joint assembling equipment until whole shield pipe joint assembling is finished. The rectangular-section pipe joint shield assembling method solves the problems that in half-pipe-section shield construction in the prior art, a rectangular large-section shield is difficult to construct, the pipe joint assembling process is complex, the construction progress is slow, and the safety degree is not high.

Description

technical field [0001] The invention relates to the technical field of shield tunneling, in particular to a pipe section shield assembly method with a rectangular section. Background technique [0002] At present, in the construction of comprehensive underground pipe corridors, most of the pipes with round cross-sections are constructed without excavation, and even some pipes with rectangular cross-sections are mostly constructed with pipe jacking. However, if pipe jacking is used for large-section rectangular pipelines, the top distance is not too long, only about 100 meters. It is very difficult to construct rectangular large-section shields. The assembly process of pipe joints is complicated, the construction progress is slow, and the safety is not high. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a method that overcomes the difficulty of constructing a rectangular large-section shi...
