Image Number 4 for United States Patent #4295757.

An apparatus for burying a pipeline in a sea bed having a spoil collection scoop surrounding the air lift intake portions of the sled. The apparatus includes a jet sled having jetting legs for disposition on the opposite sides of a pipeline to be buried and directing a stream of high pressure water through nozzles into the sea bed to form a trench for the pipeline, and air lift conduits each providing spoil intake and spoil discharge portions for removing spoil cuttings from the trench cut by the jetting legs. A spoil collection scoop surrounds the intake portions of the air lift conduits, collecting and consolidating spoil cut by the jetting legs at the air lift conduit intake portion for discharge of the cut spoil material from the trench into which the pipe will be buried.
