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 the foreign matter includes reciprocally pulling the device through the pipe and injecting high pressure air into a containment area (134) to force any extricated foreign matter to the surface.
Un organe cylindrique à lames (12) pourvu d'ajutages (58) d'injection de fluide sous haute pression coupe et balaie des matières étrangères aquatiques (108) de la surface intérieure de canalisations sous-marines (60). Selon ce procédé d'enlèvement de matières étrangères, on tire le dispositif animé d'un mouvement alternatif à travers les canalisations et on injecte de l'air sous haute pression dans une zone de confinement (134) afin d'expulser jusqu'à la surface toutes matières étrangères enlevées.
