Abstract (en)
The invention relates to a device (1) for displacing bottom material (26) under water. The device comprises a frame (2) which is displaceable under water by being coupled to a vessel (17). The frame (2) comprises a tubular liquid container (3) with outflow openings (7) for a liquid directed toward the bottom (22), wherein the outflow openings (7) are placed such that during use the liquid is injected into or against the bottom (22). The device further comprises suction means (5a, 5b) driven by means of a drive (18) for supplying the liquid under pressure from a source to the container (3), wherein the suction means are situated under water during use, in addition to a pusher member (13) bounded on a base part thereof by a cutting edge (14). The invention also relates to a method for displacing bottom material under water by making use of a device according to the invention. The invented device can be utilized more flexibly than the existing device and is moreover more efficient.
