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.

A pipe support system. The pipe support system comprises a first wedge block and a second opposing wedge block. Each of the blocks comprises a base having walls. In addition, each of the blocks supports an angled roller bearing. The roller bearings are configured to support a joint or section of pipe along an outer diameter of the pipe. Beneficially, the distance or spacing between the wedge blocks may be adjusted by an operator to accommodate sections of pipe having different diameters. A method for supporting a section of pipe is also provided.

A system for straightening downwardly-bowed underground pipeline using a means of pumping expandable fluid into substratum below the pipeline bow. The system includes an apparatus for identifying the bowed section of underground pipeline, and a device for delivering expandable liquid to the target site beneath the pipeline bow. The apparatus includes a frame supporting a series of probe-rods driven into contact with the top of the pipeline, to locate the bowed section. The device for straightening downwardly-bowed underground pipeline uses a means of pumping expandable fluid into substratum below the pipeline bow; the device comprises an elongated shaft having a trailing end and a leading end and defining a fluid pathway from the upstream trailing end to the downstream leading end. The trailing end is adapted to secure fluid communication between the fluid pathway and the means of pumping expandable fluid, and the fluid pathway terminates in at least one downstream fluid pathway exit; the leading end also including a means of shielding said pathway exit and diverting the fluid from continued downstream travel.

A system for installing and labeling lay flat irrigation pipe in flooded rice and furrow irrigated fields, and a trailer for laying a roll of pipe in an irrigated field. The trailer includes a flexible hitch assembly positioned at a first end of the trailer, wherein the hitch assembly couples the trailer to a vehicle. The trailer also includes a distribution assembly positioned at a second end of the trailer, wherein the distribution assembly includes a spindle and wherein the distribution assembly couples the roll of pipe to the trailer; and a gooseneck frame including a first end coupled to the hitch assembly and a second end coupled to the distribution assembly, with an upper member between the first end and the second end of the gooseneck, wherein the upper member of the gooseneck is elevated relative to the hitch assembly. The trailer may also include offset tandem wheels with a furrow assembly to facilitate the creation of a furrow ditch and for traversing flood irrigated levees for the purposes of installing lay-flat polyethylene pipe for irrigation. The trailer may also include an adjustable telescoping hitch to adjust to various vehicle hitch heights. The system includes a labeling system for indicating the punch size needed along the pipeline during installation. A computerized hole selection plan is developed and transferred to a microprocessor device, where sensors or a global positioning system is co-locate the device so the punch label can be applied along the pipe during installation.

The present disclosure provides a system for vertical deployment of leaching lines onto a slope of a mine leach pad. The system includes an elevated guidewire having a first end disposed at a top of the slope and a second end disposed at a bottom of the slope; the elevated guidewire being elevated above a surface of the slope; a deployment apparatus moveably coupled to the elevated guidewire and having one or more attachment mechanisms disposed thereon; and one or more leaching lines coupled to the attachment mechanisms; wherein movement of the deployment mechanism from the top of the slope to the bottom of the slope pulls the one or more leaching lines down the slope and deploys the one or more leaching lines vertically onto the surface of the slope.

Techniques for implementing and/or operating a pipe handling system that includes an inboard bore plug assembly and an outboard bore plug assembly, which facilitate plugging a pipe bore in a flexible pipe. The inboard bore plug assembly includes a first inflatable plug having a first inflatable bladder that defines a first fluid cavity and a first inflation port opening and a first inflation fluid port secured within the first inflation port opening. The outboard bore plug assembly includes a second inflatable plug having a second inflatable bladder that defines a second fluid cavity, a second inflation port opening, and a bore port opening, a second inflation fluid port secured within the second inflation port opening, and a bore fluid port secured in the bore port opening to enable the pipe bore in the flexible pipe to be pressurized to an elevated fluid pressure.
