Tunneling machine and construction method thereof

Abstract

The invention provides a tunneling machine and a construction method thereof. The tunneling machine comprises a tunneling machine body, a traction pulling point is arranged on the tunneling machine body and connected with a traction rope, the traction rope penetrates through a to-be-tunneled area, and the traction rope is connected with traction equipment at a receiving end. The construction method comprises the following steps that the positions, corresponding to a starting end and the receiving end, of the traction pulling point are measured and positioned; the traction rope is sent from thereceiving end to the starting end; the traction rope is connected with the traction pulling point and the traction equipment; and the traction rope performs traction and deviation rectifying on the tunneling machine body. The tunneling machine and the construction method thereof have the advantages that the jacking distance of the tunneling machine is increased, the number of relay wells is decreased, and investment is saved; the jacking control difficulty of the tunneling machine is reduced, more devices and methods are provided for deviation rectifying of the tunneling machine, constructionprecision is improved, and the engineering quality is improved; and the foundation of the construction precision of the tunneling machine is improved, the assembly precision between unit pipe jointsof a 'CC' construction method is improved, and the joint quality and the waterproof effect of the pipe joints are improved.

Description

technical field [0001] The invention relates to underground engineering, in particular to a boring machine and a construction method thereof. Background technique [0002] With the in-depth advancement of infrastructure construction such as sponge cities, urban three-dimensional transportation, and civil air defense projects in my country, there are diverse needs for underground engineering sections. In the future, construction fields such as underground commercial complexes, subway projects, underground parking lots, comprehensive utility corridors, highway and railway tunnels or box culverts will have a large number of diverse space development needs. [0003] Commonly used construction methods for underground space development include open-cut method, concealed excavation method, pipe jacking method, shield method, "CC" construction method and so on. The pipe jacking method or shield tunneling method has many advantages such as safety, little impact on the ground environ...
