Method and device for embedding cables or the like into an underwater ground

A method for embedding a cable or the like into an underwater ground in which method the cable is introduced into a zone of reduced density which is produced progressively in the underwater ground by a flushing process, and upon meeting with ground formations which are only insufficiently loosened by the flushing process, the underwater ground is mechanically loosened in the flushing area during performing the embedding process said mechanical loosening being performed in an area which is, in the embedding direction, disposed ahead of the center of the flushing area, wherein the mechanical loosening is automatically controlled in dependence upon the flushing depth so that it is initiated if the flushing depth obtained with the flushing alone becomes smaller than a predetermined minimum value, the mechanical loosening is performed to a working depth which is larger than the minimum value but smaller than the maximum flushing depth obtainable with soft ground formations, and the mechanical loosening is terminated when the flushing depth has exceeded the working depth of the mechanical loosening over a predetermined period of time.
