Abstract

An apparatus for burying cables or flexible tubular pipelines 9 in the sea bed, comprises on a trolley or carriage 1 movable on the sea bed and connected to the surface vessel from which the said trolley or carriage 1 is controlled and from which the pipe 9 to be laid is submerged, a front part incorporating a rotary cutting disk 4 able to rotate about a horizontal shaft, whilst being driven by motor means 5 and which is peripherally provided with cutting members 7, and a rear part in the form of a chute 8 which receives from the top the pipe 9 to be laid and guides it to the bottom of the trench dug out by the front part during the controlled forward travel of the carriage 1, the rotary cutting disk 4 and the chute 8 for receiving and guiding the pipe 9 to be laid being integral with a chassis 13 which is vertically movable with respect to the carriage 1, wherein the receiving and guidance chute 8 is removed so as to pivot with respect to the chassis 13 moving around a horizontal shaft under the action of a jack 18 mounted between the movable chassis 13 and the chute 8 and wherein the chute 8 has an access door 11, particularly a hydraulically controlled access door, articulated to the top of the chute 8.
