Abstract
A cable burial system includes a cable burial tool having a base frame, a blade extending downwardly from the base frame and having a vertically oriented internal slot therein with a slot width, and a feed shoe with an arcuate feed shoe periphery and a feed shoe width less than the slot width of the blade. The feed shoe is pivotably connected to the base frame and is pivotable between a lowered position wherein the feed shoe lies within the slot, and a raised position wherein the feed shoe lies outside of the slot. The feed shoe includes a jet opening in a periphery of the feed shoe, and a source of pressurized water in an interior manifold of the feed shoe in communication with the jet opening in the periphery of the feed shoe. A guide is operable to guide a cable into the slot in contact with the feed shoe periphery when the feed shoe is in the lowered position. The guide includes a feed horn affixed to the base frame with an outlet end adjacent to the upper end of the slot and centered on the slot, and a pair of movable guide plates disposed adjacent to the upper end of the slot and centered on the slot. The guide plates are movable between a closed position centered with a first spacing sufficiently greater than the feed shoe width to permit the feed shoe to lie therebetween, and an open position having a second spacing greater than the first spacing. The cable burial tool is pivotably connected to a burial sled.
