Problems solved by technology

For tunnels constructed with TBM, if a rockburst occurs during tunnel excavation, it is difficult to control the instantaneous large deformation of the surrounding rock with traditional support such as segments, which will lead to damage to the support system, TBM equipment will be buried, and the construction progress will be affected. Huge economic losses and even casualties

Abstract

The invention discloses a tunnel rock burst control type TBM system and method. The tunnel rock burst control type TBM system comprises a cutter head, a telescopic shield, a reinforcing mesh lifter, a steel bracket lifter, a concrete ejector, a movable supporting part, a pipe piece mounting device and an anchoring piece mounting device which are coaxially arranged and are sequentially connected and fixed through transmission pieces from left to right; the cutter head, the concrete ejector, the anchoring piece mounting device and the pipe piece mounting device are rotatably arranged around a central shaft; and the telescopic shield and the reinforcing mesh lifter rotate around the central shaft and stretch out and draw back in the radial direction. The tunnel rock burst control type TBM system is simple in structure, the tunnel rock burst control type TBM system is used for excavating a tunnel and constructing a reinforcing mesh-anchoring piece-high-strength arch frame-pipe piece combined supporting system, the risk of rock burst in the tunnel TBM construction process is reduced or avoided, and the safety of constructors and mechanical equipment is guaranteed.

Description

technical field [0001] The invention relates to the technical field of tunnel and underground chamber construction, in particular to a tunnel rockburst control TBM system. [0002] The present invention also relates to a tunnel excavation and support method using the above tunnel rockburst control type TBM system. Background technique [0003] Rockburst is a phenomenon in which the elastic variable energy accumulated in a rock mass is suddenly and violently released under certain conditions, causing the rock to burst and eject. During the excavation process of the tunnel and after the completion of the excavation, rockbursts may occur, which poses a huge threat to the safety of tunnel personnel and equipment. At the same time, it increases the project cost and affects the process cycle time and construction progress. Especially for tunnels with large burial depth, high stress and many structures, strong rockbursts are prone to occur. Taking the Sichuan-Tibet Railway Tunnel,...
