摘要

Device (16) for sediment dredging of water bodies, preferably in docks, coastal waters or the like for producing a target depth, using an injection method, comprising - a buoyant carrier device, such. As a ship or a pontoon (14), and - a substantially transverse to the longitudinal axis (L) of the carrier device below the carrier device can be arranged, preferably in its length substantially the width of the carrier device corresponding, injection tube (18) having a plurality of mutual Distance arranged, the body of water facing nozzles (20), which is acted upon by an injection fluid, characterized in that the injection tube (18) is part of a closed tube frame (22) of fluidly connected pipes (19).
