ABSTRACT:
A multiple pipe chute installation for continually and progressively excavating a trench, laying flexible utility pipe a predetermined vertical distance apart, refining and refilling the soil around the laid pipes, and compacting the refilled soil is disclosed. The installation includes a trenching chain assembly pivotably mounted to the rear of a vehicle for excavating a trench. A multiple pipe chute assembly including a plurality of chutes is pivotably attached to a support frame extending from the trenching chain assembly. A support arm is pivotably attached to the support frame and extends rearwardly of the chute. A backfiller assembly is attached to the end of the support arm and a compacting rod is attached to the support arm adjacent the backfiller assembly. A hydraulic cylinder is attached between an extension of the support frame and the support arm. The chute assembly may be selectively linked to either the trenching chain assembly or the support arm. Therefore, the hydraulic cylinder may expand or contract to raise or lower either the support arm alone with respect to the chute assembly and trenching assembly, or both the support arm and the chute assembly with respect to the trenching chain assembly.
