Drag head for a trailing suction hopper dredger and method for dredging using this drag head
A drag head of a trailing suction hopper dredger, comprises a visor which is dragged over the bottom in a dragging direction and herein loosens soil, and a suction conduit which connects to the visor and which discharges the loosened soil. The drag head is provided with cutting bodies for loosening the soil, with the proviso that the cutting bodies comprise conical bits. Harder soil can be dredged efficiently with a trailing suction hopper dredger equipped with the drag head.
