"APPARATUS FOR THE SUBAQUEOUS ENTRENCHING OF PIPES" A B S T R A C T The invention relates to an apparatus for the entrenching of pipes in underwater beds, of the type in which a framework, provided with exca vating means, is positioned across the pipe to be entrenched and drag ged along the pipe so as to excavate two parallel trenches adjacent to both sides of the pipe, the pipe being entrenched due to the colla psing ( either spontaneous or caused by disgregating means ) of the bed zone thus remaining under the pipe already laid onto the bed. The excavated material is removed by means of a pump and discharged again, at a predetermined distance from and rearwardly of the frame work, on the entrenched pipe. The framework is provided with side sup porting skid members, by which furthermore the entrenching height is adjustable.
