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.

Provided is a guiding type miniature pipe-jacking construction method, comprising the following steps: in an originating well, perforating an operation hole in an inner wall of the originating well with a trepanning apparatus; mounting a laser orientation instrument and a laser guided drill bit, driving a guide bar connected with the laser guided drill bit into the opened operation hole with a thrusting apparatus, and driving the guide bar into a soil mass with the thrusting apparatus; jacking a plurality of mud discharging pipes following the guide bar successively into the soil mass with the thrusting apparatus; jacking a plurality of mud discharging screw rods into the mud discharging pipes with the thrusting apparatus; jacking a pipe-jacking machine head following the mud discharging pipes into the soil mass with the thrusting apparatus, a cutter head on the pipe-jacking machine head rotating to drive the mud discharging screw rods to rotate.

A pipe replacement system and cable guide frame are shown. Configurations are shown that include plurality of guide pulleys attached to the cable guide frame to define a curved path between a pipe to be replaced and a cable pulling system. Configurations are shown where a pipe breaking tool is pulled over the plurality of guide pulleys for ease of removal after a replacement operation. Configurations are also shown that include a stationary splitter adjacent to the cable pulling system to prevent jamming of the cable pulling system.

A pipe replacement system and method are shown. Configurations are shown that include a pulley that does not damage a bursting tool, as the bursting tool is pulled into a pit. Configurations are also shown that include a boom that does not need an extraction cage for the bursting tool.

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.

The present invention relates to a utility support framing system and method of use for structurally suspended concrete slabs of slab-on-voidform foundations. The inventive utility support framing system and method of use isolates utilities, hanger assemblies, and framing system components from soil so as to avoid problems created by volumetric soil changes which otherwise would damage utility lines under foundation systems. The inventive utility support framing system permits suspending utility pipes under a slab of a slab-on-voidform foundation while avoiding the problems of the prior art. The invention also relates to a novel mountable pipe clamp and method of use and a novel protective utility counterweight and method of use for transitioning a utility system from a suspended condition to a soil supported condition.
