Abstract

A TBM tunneling test bench for microwave-assisted rotary rock breaking comprises a tunneling test bench body and a microwave-assisted rock breaking system. The tunneling test bench body comprises a base, an overturning bracket, a movable bracket, an overturning oil cylinder, a thrust oil cylinder and a cutter head; the overturning bracket is hinged to the base, and the overturning oil cylinder is connected between the base and the overturning bracket; the movable bracket coaxially sleeves the overturning bracket and can axially move; the thrust cylinder is connected between the overturning bracket and the movable bracket; the cutter head is coaxially arranged in the movable bracket and can freely rotate; a cutter head rotation driving motor is mounted in the movable bracket; the microwave-assisted rock breaking system is mounted between the movable bracket and the cutter head; and a rock sample bearing box is arranged on the overturning bracket on the opposite side of the cutter head; and the hobbing cutter is opposite to the surface of a rock sample. The tunneling test bench can be switched between a vertical rock breaking simulation state and a horizontal rock breaking simulation state, and a TBM tunneling simulation test under the microwave-assisted rotary rock breaking condition and multi-hob rock breaking under the microwave effect can be carried out.

Description

technical field [0001] The invention belongs to the technical field of rock mass and tunnel engineering, and in particular relates to a TBM tunneling test bench for microwave-assisted rotary rock breaking. Background technique [0002] TBM (full-face hard rock tunnel boring machine) has been widely used in tunnel projects that need to pass through rock formations such as railways, hydropower, highways, and subways. The rock-breaking technology of cutterheads and cutters is the core of TBM technology. For rock technology, it is necessary to use the TBM excavation comprehensive test bench to accurately simulate the rock breaking process of the hob in the laboratory. [0003] The TBM tunneling comprehensive test bench can conduct TBM tunneling simulation tests on different types of rocks or similar materials, and can carry out multi-cutter rock breaking tests for different cutters, cutter spacing, cutting speed, penetration, etc., and study the damage caused by different cutter...
