ABSTRACT:
A generally horizontal pipe extends across the bottom of a waterway to be dredged and, in some embodiments is connected to a suction pump at or below the low water level. Lateral passageways are distributed along the length of the horizontal pipe with a number of smaller orifices located along the pipe's length between the passageways. Any sediment build-up above a passageway and several nearby smaller orifices, which may be due to a passageway being clogged with a large object, is cleared by a manually operated source of high pressure fluid where fluid jet streams are directed against the build-up of sediment in a manner so as to churn or break up the sediment build-up and permit the sediment to be drawn into adjacent passageways and orifices.
