Abstract

Described is a device for dislodging an underwater bottom. The device comprises the combination of a cutter suction dredger (1) for dislodging the underwater bottom (9) and an excavator (30) for discharging the dislodged ground portions. The cutter suction dredger (1) is provided with a cutting device (10) which comprises attaching means (103) for attachment to a ladder (2) of the cutter suction dredger (1) and in attached state is moved through the underwater bottom (9) in a lateral sweeping movement (13) of the ladder (2), wherein the cutting device (10) comprises a revolving body (106) which is rotatable around a rotation axis (102) running substantially perpendicularly of a longitudinal direction (21) of the ladder (2), wherein the cutting device (10) comprises elongate members (105) extending outward from an outer surface of the revolving body (106) and the elongate members (105) are provided with one or more cutting tools (115). The invention likewise relates to a method in which the device is applied.
