Two-step underground pipe-driving construction process

Abstract

The two-step underground pipe-driving construction process includes setting working well and accepting well on the two ends, between which the pipe is laid, for pipe driving construction, driving one guide steel pipe between the working well and the accepting well with a miniature remote-controlled guide pipe driving machine based on designed axis requirement, and subsequent reaming to shape the hole with a capstan reamer or an extruding reamer while driving the pipe one section by one section, and pushing out guide steel pipe with the capstan reamer or the extruding reamer to the accepting well for recovery.

Description

technical field [0001] The invention relates to an underground pipe jacking construction method, in particular to an underground pipe jacking two-step construction method. Background technique [0002] At present, in the construction of municipal pipelines, it is often necessary to dig trenches underground to lay pipelines and repair pipelines. The construction period of the excavation method is long, especially the underground pipelines in the urban center section are very dense, and the pipelines overlap and overlap. If you want to lay new Pipelines will not be able to be excavated by traditional excavation methods, and if there are buildings on the surface, they will not be able to be excavated. Excavating roads in busy cities will bring great inconvenience to traffic and people’s lives. The existing underground pipe jacking The construction method is to drill two working wells at two places where pipelines need to be laid, and then use hydraulic pipe jacking equipment to...

[0002] At present, in the construction of municipal pipelines, it is often necessary to dig trenches underground to lay pipelines and repair pipelines. The construction period of the excavation method is long, especially the underground pipelines in the urban center section are very dense, and the pipelines overlap and overlap. If you want to lay new Pipelines will not be able to be excavated by traditional excavation methods, and if there are buildings on the surface, they will not be able to be excavated. Excavating roads in busy cities will bring great inconvenience to traffic and people’s lives. The existing underground pipe jacking The construction method is to drill two working wells at two places where pipelines need to be laid, and then use hydraulic pipe jacking equipment to jack pipes one by one in one working well, thereby completing the trenchless pipeline laying construction method, but this method is subject to jacking Due to the limitation of tube diameter, it is impossible to realize the multi-purpose function of one machine
