摘要： A tunneling machine convertible between a "closed mode" and an "open mode" of operation, having a rotatable cutterhead with muck openings communicating with a pressurizable cutterhead chamber and a pressure maintenance system to stabilize the tunnel workface when operating in the "closed mode". In the "closed mode" low slurry flow is employed as a liquid pressure balance solely to support the unstable tunnel face. Low slurry flow is supplied through a pressure bulkhead sealing the cutterhead chamber and pressurized conveyor means through the bulkhead removes tunneled material from the cutterhead chamber. A pressure lock connected to the pressurized conveyor means transfers tunneled material to dewatering and reservoir/accumulator means operated at substantially atmospheric pressure. Slurry, with at least most of the solids removed, is recycled to the slurry inlet at a controlled low flow rate matching the rate of removal of tunneled material and slurry from the tunnel face so the otherwise unstable tunnel face is maintained stable. In the "open mode" of operation, for use in boring a self-stabilizing tunnel face, the pressure bulkhead is removed and a second conveyor, such as a belt conveyor, is disposed adjacent to the "closed mode" conveyor to withdraw cuttings from the cutterhead chamber.

摘要： Front and rear shields are telescopically joined together. The front shield carries a power driven rotary cutterhead means. Thrust rams are provided between the two shields for pushing the forward shield forwardly relative to the rear shield while the cutterhead means is being operated to mine the tunnel face, and also to pull the rear shield forwardly relative to the front shield. The rear shield includes a gripper assembly for reacting thrust and torque and a plurality of auxiliary thrust rams which extend rearwardly from the rear shield to react against forward end portions of a tunnel lining which is erected under cover of a tail section of the rear shield. A pair of side placed torque cylinders are interconnected between frame portions of the two shields and serve to transmit counter-rotational torque from the cutterhead support of the front shield back to the rear shield. The torque cylinders are adapted to accommodate relative axial movement between the two shields and are operable to roll the shields back into proper position after they have been rolled out of position by the counter-rotational torque generated by rotation of the cutterhead means.
摘要翻译：前后盾可伸缩连接在一起。前挡板带有动力驱动的旋转刀盘装置。在两个护罩之间提供推力杆，用于相对于后挡板向前推动前罩，同时刀盘装置被操作以挖掘隧道面，并且还相对于前护罩向前拉动后护罩。后挡板包括用于使推力和扭矩反作用的夹持器组件以及从后挡板向后延伸的多个辅助推力柱塞，以与后盾构件的尾部部分的盖下竖立的隧道衬里的前端部分反作用。一对侧放置的扭矩缸在两个屏蔽件的框架部分之间互连，并用于将反向旋转扭矩从前屏蔽件的刀架支撑件传回到后屏蔽件。转矩缸适于容纳两个屏蔽件之间的相对轴向运动，并且可操作以通过由刀盘装置的旋转产生的反向转矩而将屏蔽件翻转回适当位置。

摘要： A hopper and hood combination for muck transfer in a tunneling machine, and a tunneling machine having the same, in which a muck collar is mounted to a cutterhead support and projects into a rotatable cutterhead. A muck chute on the muck collar feeds earth to an earth conveyer when the muck collar and muck chute are in a hopper orientation. The muck chute and muck collar are rotatable relative to the earth conveyor to a hood orientation in which the muck chute restricts earth flow to the earth conveyor. Rotation of the hopper/hood from one orientation to the other is by brief interconnection thereof to the cutterhead without any necessity for any disassembly or reconstruction of the tunneling machine.

摘要： A shaft boring machine including a rotatable cutterwheel assembly with a horizontal axis mounted on a carriage having vertical travel. The carriage is mounted on a slewing base frame and rotates about the vertical axis of the machine. An excavating unit for muck removal is mounted opposite the cutterwheel on the slewing base frame and loads directly from the shaft bottom into a muck hopper. When the hopper is full, it is discharged into a hoist bucket which is hoisted to the surface. The machine is positioned in the shaft by upper and lower gripper systems. Walking cylinders between the two gripper rings advance the machine up or down the shaft.A method of boring vertical shafts in medium and hard rock which includes the steps of: (a) providing, radially of the shaft, a cutterwheel assembly for cutting the rock; (b) while rotating the cutterwheel assembly about its horizontal axis, plunging the rotating cutterwheel downwardly into the rock; (c) slewing the rotating cutterwheel assembly around the rock work face and about the central vertical axis of the shaft; and, (d) removing the rock cuttings from the work face.

摘要： A tunnel boring machine particularly adapted to operate at substantial depths below the earth's surface. The machine comprises a head section comprising a cutter head that is rotatably mounted to a support structure. There is a plurality of gripper shoes spaced circumferentially around the support structure, and these are operated to grip the tunnel wall and be selectively operated to advance the machine in the tunnel as the tunneling operation progresses. Also, there is a roof shield positioned immediately behind the cutter head. There is also a pair of support shoes supported from the support structure by links having curved bearing surfaces to maintain the machine at the proper distance above the tunnel invert. There is a beam structure having a forward end connected to the support structure by a universal connection, and the beam structure is supported by a rearwardly positioned gantry. There is also a positioning means to rotate the support structure relative to the beam structure so as to move the head section both laterally and vertically, and also to correct roll orientation.
