Abstract: A hard rock tunnel boring machine combining microwave heating with high pressure water cutting for assisting in rock breaking includes a tunnel boring machine body, a microwave heating assisted rock breaking system and a high pressure water cutting assisted rock breaking system, wherein the microwave heating assisted rock breaking system is arranged on the tunnel boring machine body, and is used for heating and cracking a rock; and the high pressure water cutting assisted rock breaking system is arranged on the tunnel boring machine body, and is used for performing hydraulic cutting on the rock. A rock breaking sequence lies in that the microwave heating assisted rock breaking system is used for heating and cracking the rock, then the high pressure water cutting assisted rock breaking system is used for performing hydraulic cutting on the rock, and finally, the tunnel boring machine body is used for squeezing and breaking the rock.

Abstract: Provided is a TBM tunneling test bench for microwave-assisted rotary rock breaking including a tunneling test bench body and a microwave-assisted rock breaking system, wherein the tunneling test bench body includes a base, a turnover bracket, a movable bracket, turnover oil cylinders, a pushing oil cylinder and a cutter head; the turnover bracket is hinged to the base; the turnover oil cylinders are connected between the base and the turnover bracket; the movable bracket coaxially sleeves the turnover bracket; the pushing oil cylinder is connected between the turnover bracket and the movable bracket; the cutter head is coaxially located in the movable bracket, and rotates freely; cutter head rotation driving motors are 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 and placing box is arranged on the turnover bracket on an opposite side of the cutter head.
