An elastic film-type valve is provided in the earth discharging pipe, which valve expands and contracts diametrically by means of fluid pressure to open and close the interior of the earth discharging pipe. A gate mechanism follows the elastic valve and adjusts the sectional area of the space through which earth and sand pass inside of the earth discharging pipe. The gate mechanism narrows the sectional area of the earth discharging pipe at the outlet side of the elastic valve so as to create a substantially uniform earth pressure upon the entire elastic valve to inhibit blockages and eruptions that might otherwise occur.

    Abstract: 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.

  • Patent number: 5127711
    Abstract: 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.

  • Patent number: 5125768
    Abstract: A method and apparatus for producing an underground pipeline from an excavated hole uses a drill head with a suitable tool attached thereto. Loosened soil is transported out of the drilled tunnel with a transportation drum containing an internal spiral. The drum is supported by a roll devices fixed to outer pipes. Rotating movement is transmitted to the rotating drill head from the transportation drum which is driven by a motor. Cylinders push the whole system and force is transmitted by the outer pipes to the drill head. Guiding of the drill head is accomplished with fluid actuators. Attachment and removal of the drill tool is accomplished through a free hole in the transportation drum and a central hole in the drill head, and the free hole and central hole also allow observation of the drill tool and tunnel face during drilling.

  • Patent number: 5056655
    Abstract: Conveyor belt supporting modules associated with an endless conveyor belt assembly for conveying mined material from a mine bore to the mouth of the bore allows for necessary length of conveyor belt to be fed into the mine, and convey material from the mine, as the bore lengthens so that the conveyor belt always extends from adjacent the cutting site to the bore mouth. Each module has a carriage frame with a number of conveyor belt supporting return rollers extending between the frame sides, and a number of conveyor belt supporting trough roller sets mounted above the return rollers and spaced from each other from the front to the rear along the frame. The carriages have axles and wheels to allow movement into a bore, and they are connected together by couplers. The supporting trough roller sets are mounted for pivotal movement on a frame side to expose the return rollers so that the endless belt can be laid in place simply and quickly.

  • Patent number: 5022789
    Abstract: There are disclosed a method and a machine for constructing a shaft having a substantially circular cross-section. According to the present invention, the shaft having a shotcrete formed on a peripheral wall thereof can be easily constructed. The shotcrete can be promptly formed on the peripheral wall by spraying concrete on the wall above the water level of the water in the shaft before the wall is damaged. Also, muck excavated from a working face of the shaft can be efficiently conveyed therefrom to outside of the shaft even if the shaft has a depth of more than hundreds of meters.

  • Patent number: 5005911
    Abstract: A tunneling machine body carrying a rotary cutterhead can be advanced continuously by exerting advancing thrust force on it, first by top and bottom jack bipods reacting from top and bottom anchor shoes, respectively, in anchored condition against the tunnel wall and alternately by side jack bipods exerting advancing force on the tunneling machine body and reacting from side anchor shoes set in anchored condition against the tunnel wall. The anchor shoes are floating relative to the tunneling machine body and connected to it only by the bipods producing the thrust for advancing the tunneling machine body. The top and bottom anchor shoes are directly connected by two pairs of upright fluid-pressure shoe-setting jacks extending chordwise between such shoes. The side anchor shoes are directly connected by two pairs of transverse fluid-pressure shoe-setting jacks extending chordwise between such shoes.

  • Patent number: 4848963
    Abstract: The earth pressure shield for a tunnel and/or gallery excavator has a front working compartment formed by a separating wall having a digging tool and an annular reinforcing space substantially triangular in cross section positioned directly in front of the separating wall. So that an extensive restructuring of the machine is not necessary when moving from soft earth to hard ground, the annular reinforcing space is provided with a lower fluid feeder, a controlled upper pressurized air feeder, a plurality of fluid conductor pipes which are guided from below to an upper fluid outlet opening into the working compartment, and a fluid level controller. The invention is based on the consideration that a reliable and satisfactory support of the local front wall is only possible when the local front wall in the vicinity of the roof can be supplied with a fluid.

    Abstract: The earth pressure shield contains a front working compartment having a digging tool and formed by a separating wall. An annular space is formed in the front working compartment with a top region connected with a regulated pressurized air feed and with a bottom region open to the digging tool so that dug or mined earth material is removable with the help of a conveyor unit. At least one fluid pipe is guided from a fluid chamber with a level controller and a fluid feeder to a fluid outlet open to the digging or mining tool in the working compartment. An especially reliable operation is attained when a bulkhead space is provided by partitioning behind the working compartment and/or the circular space formed with an immersed wall. This bulkhead space is connected in its upper region with the top region of the annular space by an opening in the separating wall and includes the fluid chamber in its lower region.

  • Patent number: 4790395
    Abstract: Pipe-driving apparatus used to create a pipe line of small diameter uses a pressing station in an access trench to drive in pipe sections one by one. A boring head and conveyor worm operates at the front of the pipe line in a working pipe section on which a cutting shoe is swivably mounted. The worm is a spiral flight on a drive shaft which runs within an open fronted container on which a drive unit for the boring head and the worm is mounted. Hydraulic bracing units mounted to the container can be swung out and engaged with stops in the working pipe section to brace the container during the filling operation. Projections on the container engage with the shoe and the bracing units can be used to steer the shoe. When the container is filled the bracing units re stowed and the container is withdrawn back down the pipe line to the access trench for discharging the material.
