Abstract

This invention concerns a drag head for a trailing suction hopper dredger which essentially consists of a structure connected to a suction pipe, with a visor (2) rotating around an horizontal axis (6), in which a series of teeth (10) are applied for breaking up the sand, which are arranged along a line which extends perpendicularly with respect to the direction of motion of the drag head, and a first series of jet pipes (9) for injecting water under high pressure, which are arranged along a line parallel to the line and in front of said teeth, wherein at least one second series of jet pipes (12,12') is provided along a line parallel to and behind the line of said teeth Figure 1.
