摘要： Device for burying a line, for instance a cable, a pipeline or similar in the sea bed, and comprising a number of rearward-facing nozzles (viewed in the direction of digging) each of which is connected to a pressure liquid hose and positioned to either side of the centre line of the device. A series of devices for burying a line in the sea bed are known which incorporate nozzles. Examples of these are to be found in US Patents 3.217.499 and 3.505.826. This invention is aimed at improving the existing types of digging device so that a deep trench may be dug, the line laid and the trench back-filled all at the same time. It is intended that the device as produced should be both robust and light in weight. The invention achieves this by the nozzles (4, 5) being arranged in pairs (3), with one of the nozzles (5) in each pair (3) being inclined downwards and backwards at an angle and the other nozzle (4) being inclined upwards and backwards at an angle.
