Abstract

The invention discloses a remote control advance tunneling TBM and a construction method thereof, and solves the problems that in the prior art, in tunnel excavation, the rock burst risk coping capacity is low and the safety coefficient is low. The advance tunneling TBM comprises an advanced tunneling device and a movable console, and the advance tunneling device is connected with a telescopic belt conveyor; pipelines of the advanced tunneling device are concentrated to a first quick-plug connector; the first quick-plug connector is mounted on the telescopic belt conveyor; a controller and a pipeline winding and unwinding mechanism are arranged on the movable console, pipelines on the controller are concentrated into a quick-plug pipeline, the quick-plug pipelines are wound on the pipelinewinding and unwinding mechanism, a second quick-plug connector is arranged at the free end of the quick-plug pipeline, and the second quick-plug connector is matched with the first quick-plug connector in an inserted mode, so that the pipeline disassembly and assembly speed is high, and protection is easy. The advantages of the TBM and the advantages of a drilling and blasting method are fused, the TBM with remotely controlled tunneling carries out excavation by a certain distance in advance, and then is rapidly switched to the drilling and blasting method for construction, and construction is safer and more efficient.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a remote-controlled advanced tunneling TBM and a construction method thereof. Background technique [0002] With the vigorous development of my country's infrastructure construction, the proportion of long tunnels in the construction fields of highways, railways, water conservancy and hydropower is increasing, especially in projects such as single-hole double-lane high-speed rail tunnels and single-hole double-lane expressway tunnels. The average diameter of the excavation section exceeds 10m. The conventional drilling and blasting method has low construction efficiency, high labor intensity, and high safety risks, especially the weak ability to deal with rockburst risks, which causes great harm to the safety of personnel and equipment. Although the use of full-section TBM (rock tunnel boring machine) has advantages in terms of safety, environment, and construction pe...
