Abstract: A portable extraction tool facilitates soil stabilization applications that utilize compaction grouting. Compaction grouting involves installing grout injection casing into the ground in fixed-length sections to depths limited by soil compaction or bedrock. The casing is then removed in stages.

Pulling power is provided by a pair of hydraulic cylinders. Gripping strength is provided by a progressive chuck mechanism that secures injection casings on upward movements of the cylinders and releases casings on downward movements, without damaging the reusable casings. Stability and strength are provided by a heavy, large-footprint base plate.
