Abstract: A pipe puller system and methods of pipe extraction are shown. In one example a pipe to be replaced is pulled by attaching a pulling force to multiple locations along a length of the pipe. In one example pulling forces can be varied between different attachment locations to better control or eliminate tearing of the pipe. In one example, a pipe loosening device may be used prior to pulling the pipe from the ground.

Abstract: A cable puller and a related method of use are provided. The cable puller includes a frame, a winch mounted to the frame, a frame mount and one or more redirection pulleys that guide a cable. The mount is mountable to an arm of a piece of equipment, e.g., excavator, backhoe, loader, etc., and configured to allow manipulation and tilting of the frame to align the redirection pulley at a level and orientation relative to an underground tubing that is to be decommissioned and/or replaced. A deflection plate can be joined with the frame forward of the pulley to protect the pulley if the cable draws a portion of the underground tubing toward it. A splitting wedge can be joined to the frame to fracture underground tubing drawn toward the plate or pulley. Related methods of use also are provided.

Abstract: A method for enlarging a crushed section of a ductile pipe. A wire rope having a bead or plurality of beads attached to the rope is placed in a ductile pipe. When a series of beads is used, each of the beads is sequentially larger. The wire rope is pulled through the crushed section, and the ductile pipe conforms to the larger diameter of the beads. The crushed section of pipe may be expanded so that a larger wire rope suitable for pipe extraction may be passed through. Alternatively, the pipe may be reformed and expanded to near or greater than its original size. The pipe may then be coated or a smaller slip-lined pipe may be placed within the original pipe.

Abstract: A pipe loosening device and methods are shown. In one example, the pipe loosening device enables a method wherein a pipe to be replaced is deformed but not burst, and a portion of a sidewall of the pipe is forced outward into the surrounding soil to compact a local region of the surrounding soil and loosen the existing pipe. The pipe may then pulled from the ground along an axis of the pipe.

Abstract: A rotary drill bit for use with a horizontal directional drill string. A coupler at a proximal axial end is configured to attach the rotary drill bit to a drill head at a distal end of the drill string. A cutting portion at a distal axial end is provided with a plurality of vanes with respective cutters that operate to cut a hole in earth when the rotary drill bit is rotated about a central axis. The plurality of vanes project radially outwardly from a surface of the cutting portion such that the surface forms respective troughs circumferentially interspersed with the plurality of vanes. A plurality of engagement features is positioned axially within the cutting portion and radially inward of an outer cutting diameter to facilitate attachment of a product pullback device between the plurality of vanes without removing the rotary drill bit, or any portion thereof, from the drill head.

Abstract: Embodiments and methods relate to pulling and installing a product line along an underground arcuate path beneath an obstacle, including pulling the product line for an extended length (i.e. a length that might otherwise be deemed impracticable) along the underground arcuate path beneath the obstacle. Embodiments also relate to a pulling apparatus for installing a product line using a casing along an underground arcuate path beneath an obstacle, having a casing pull head connected to the casing, a product line pull head assembly connected to the product line, and a pull bracket connected to the product line pull head assembly and to the casing pull head sleeve frame.
