A device for filling a ditch in the sea bed to cover a pipe placed therein, including two nozzle assemblies (6, 7) closely spaced from the sea bed on either side of a trench (1) dug therein. The nozzles are pointed at the sea bed and said trench and supplied with pressurised water to be directed continuously into the sea bed on either side of the trench to move material from the sea bed into the trench as the device travels therealong, and thereby at least partially fill said trench. A guide assembly (14) is provided for channeling the flows created by the nozzles (6, 7).
Le dispositif comprend deux ensembles d'ajutages (6, 7) disposés à faible distance au-dessus du fond sous-marin, de part et d'autre de ladite tranchée (1) creusée dans celui-ci, lesdits ajutages étant orientés en direction du fond sous-marin et en direction de ladite tranchée et étant alimentés en eau sous pression pour projeter de manière continue des jets d'eau dans le terrain constituant le sol sous-marin de part et d'autre de la tranchée, de manière à déposer des éléments dudit terrain dans la tranchée au fur et à mesure de la progression du dispositif le long de la tranchée et ainsi combler au moins partiellement cette dernière, des moyens (14) de guidage étant prévus pour canaliser les écoulements créés par les ajutages (6, 7).
