Abstract
A drag head (1) of a trailing suction hopper dredger is disclosed. The drag head comprises a visor (2) which is dragged over the bottom and herein loosens soil, and a suction pipe (3) which is connected to the visor (2) and which discharges the loosened soil. The visor (2) comprises at least two individually movable pressure elements (21, 22, 23, 24) transversely of the dragging direction which comprise a number of substantially disc-shaped penetrating bodies (51, 52, 53, 54). The penetrating bodies transmit forces to the bottom via their peripheral edge under the influence of the weight of the pressure element in which they are received, whereby the bottom is broken. The drag head is stated to have an improved efficiency.
