Abstract: A machine for underwater trenching for pipelines in which a sled (1) comprising two pipe loops (2) arranged in vertical planes at opposite sides of the pipeline (4) and interconnected by transverse pipes (3) is supported on and guided for movement along the pipeline by rubber-faced rollers (6, 7, 8, 9). High pressure water is supplied to the loops through connection (20). Nozzles (18) in the front vertical runs of the loops (2) break up the soil in the face of the trench (5). Nozzles (15) of water jet pumps suck soil from the trench through the forwardly facing inlets (11), adjacent the bottom of the sled, of two eductor tubes (10) carried by the loops (2) at opposite sides of the pipeline, and discharge it through discharge outlets (14) directed respectively outwardly sideways and mainly rearwardly of the sled. The water and soil discharge produces a reaction which propels the sled forwards.
