摘要: A bladed cylindrical member (12) with high pressure fluid jet nozzles (58) cuts and sweeps aquatic foreign matter (108) from the inside surface of underwater pipes (60). The method for removing includes reciprocally pulling device through pipe injecting air into a containment area (134) to force any extricated surface.
