Abstract: A method of moving an underground pipeline including the steps of: driving a casing into a soil proximate to the pipeline; deploying a pivoting wand from the casing about a pivoting axis, the pivoting wand having a plurality of cutting nozzles that are coupled to a fluid conduit having a longitudinal extent in the casing relative to a longitudinal axis; pressurizing the fluid conduit to thereby send fluid through the cutting nozzle to soften the soil in a direction in which the wand deploys; rotating the pivoting wand; conducting the softened soil up through the casing to form a cavity in the soil proximate the pipeline, the cavity in the soil having a shape reflective of the movement of the pivoting wand in the rotating step; positioning a lifting device beneath the pipeline. And, lifting the pipeline with the lifting device thereby drawing the pipeline toward or into the cavity.

Abstract: An extraction/grouting device which includes a fluid conduit having a longitudinal extent along a longitudinal axis, a pivoting wand and at least one cutting nozzle. The nozzle being in fluid communication with the fluid conduit. The cutting nozzle being coupled to the pivoting wand that is pivotably extendable relative to the longitudinal axis.

Abstract: A structural pile sheet spur including a void creating section located in a fore part of the spur, a pile sheet interfacing section located in an aft part of the spur, and a fluid delivery passageway located in or adjacent to the pile sheet interfacing section.
