ABSTRACT:
Submersible backfill machine for covering a submerged conduit disposed within a trench in a seabottom with material from the sea bottom, which includes a sled positionable over the conduit on the sea bottom. A pump is supported by the sled and is connected to an intake head that is adapted to pick up sea bottom material entrained in water drawn into the pump. A dispersion nozzle is connected to the discharge side of the pump to cause the entrained sea bottom material to settle into the trench and cover the conduit.
