Abstract: A guided boring machine includes a cutter head, a steering head and an internal casing with an auger therein for conveying material cut by the cutter head towards the rear end of the auger. The boring machine bores a tunnel from a launch pit to a target pit along a desired boring direction and simultaneously installing a selected one of a plurality of differently-sized product casings in the tunnel. When the internal casing is placed within a selected product casing with its internal casing longitudinal axis coincident with the longitudinal axis of the selected product casing, an annular space is formed with respect to the selected product casing. The guidance assembly includes a laser that is mounted behind the boring machine and oriented so as to direct its beam in a desired boring direction within the annular space. A target mount is mounted to the steering head inside surface. The target mount includes a roll correction slot which is parallel to the adjacent steering head inside surface. A target is mounted to the target mount and adapted to move with respect thereto. The target has a target point which is intersected by the laser beam when the cutter head is properly oriented with respect to the desired boring direction. A gradiometer is mounted to the target to indicate the roll orientation of the steering head, and a roll correction assembly is provided to roll the steering head, if desired, to adjust its roll orientation.

Abstract: A boring machine includes a steering head which is located behind a cutter head. The steering head has a plurality of steering openings spaced around its periphery. A steering component is mounted adjacent to each steering opening, and each steering component includes a steering paddle that is pivotally mounted with respect to the steering head so as to pivot about a paddle pivot axis. Each steering component also includes a linear actuator and a force multiplier. The linear actuator operates to direct an actuating force along a line that is parallel to the longitudinal axis of the steering head, and it cooperates with the force multiplier and the steering paddle so that upon operation of the linear actuator, a pivot force which is the product of the actuating force and a multiplier factor greater than one causes the steering paddle to pivot about the pivot axis.

Abstract: A boring machine includes a cutter head, an internal casing and an auger that is located within the internal casing. The cutter head and the auger are operationally connected to a rotational mechanism. A rear bulkhead is located at the rear end of the auger, and a rear hopper is located behind the rear bulkhead. The boring machine also includes means for directing material cut by the cutter head into the auger so that rotation of the auger will convey such material rearwardly to the rear hopper. The boring machine includes a transverse conveyor located behind the rear bulkhead in the rear hopper which is adapted to convey material out of the rear hopper in a direction transverse to the longitudinal axis of the auger.
