Abstract
A fluid assisted wedging and compacting device for the installation of underground cable that includes a blade with a cutting edge, two cutting faces a toe, a shoe, a cable feed tube, a pair of deflectors, a pair of grooves and a plurality of high pressure water jet nozzles. The blade is designed so that the deflectors and grooves are positioned in a vertical orientation on the lower half of the cutting faces of the blade. During use, the deflectors on the cutting faces deflect soil creating a soil free zone preventing blockage of the nozzles and allowing the water pressure from the nozzles to effectively aid the blade in cutting through the soil.
