摘要： A system for pushing and pulling rod strings through the ground or an underground pipe. The apparatus has a downhole tool attached to the distal end of the rod string. The push/pull machine has a stationary frame that is placed against the ground to provide a reaction surface. The stationary frame has an opening for the rod string to pass through. A rod gripping assembly is supported on the machine frame and moveable relative to the stationary frame. The push/pull machine has a powered rod section spinner to add or remove rod string sections from the rod string. An actuator powers movement of jaws into a spinner bowl to cause a powered gripping of the rod string section. With the rod string section gripped a motor is activated to rotate the rod string section to connect it to a rod string or disconnect it from the rod string.

摘要： A method for pushing and pulling rod strings through the ground or an underground pipe. A grip assembly is supported on a stationary frame and moveable relative to the stationary frame. The grip assembly has a slip bowl tapering from a large opening to a small opening in a first direction, a plurality of slips, and an actuator. The actuator powers relative axial movement between the slip bowl and the slips. A positioning assembly carries the grip assembly and powers its reciprocating and straight-line movement to urge the grip assembly in either a first or second direction. The grip assembly will work when operated to push or pull the pipe, irrespective of the is direction of the slips.

摘要： The present invention is directed to a rod string with a plurality of rod sections and a method for making up and breaking out the rod sections. The rod sections have corresponding pin and box ends, each having grooves and lands and an ungrooved portion. The rod sections can be connected by inserting the pin end into a box end and turning less than a full turn. A lock engagement mechanism having a first end and a second end is provided inside the rod sections and locks when the pin end is rotated into place. The lock engagement mechanism has a rotation stop which protrudes proximate the first end to prevent relative rotation of two rod sections until a key manipulates the lock engagement mechanism to retract the rotation stop.

摘要： A pipe extraction machine can be used to remove a buried pipe from the ground. The machine has a carriage with jaws that grip the buried pipe. While gripped, the carriage moves relative to a support structure to pull the pipe out of the ground. Jaws are actuated by rotating clamp plates and maintained in opposition by static horizontal grooves. The jaws remain opposed and aligned during rotation of the clamp plates. A pipe shear may remove the pipe one piece at a time. A pipe puller can be used at the back end of the pipe being removed to simultaneously install a new pipe along the same path.

摘要： A drill bit for use with a pneumatic hammer used in horizontal directional drilling operations. A compact forward face is formed on the first end of the drill bit. The forward face reciprocates against a face of a borehole. A steering face is disposed behind the forward face and is concave adjacent its first end and convex adjacent its second end, with a smooth transition between the two regions. The body has a circular profile at its second end. The drill bit displaces cobble and small rocks encountered, rather than breaking them, enhancing steering in mixed conditions.

摘要： A system for installing a drainage structure in the subsurface. The system has a casing, a drive device, and at least one fin. The casing has opposed first and second ends and defines a hollow region. The drive device is supported at the first end of the casing and configured to drive movement of the casing in a first direction. The at least one fin projects from the casing into the hollow region and is configured to buckle a corrugated metal culvert positioned at least partially within the casing when the casing is driven in the first direction. The drive device may be a pneumatic hammer or puller attached to a rod pulling machine.
