摘要： Described is a dredging head for forming a trench in an underwater bottom. The dredging head comprises a connecting part for connecting to a suction-blow conduit of a dredging vessel to be moved in a dragging direction. The dredging head further has a visor for pivoting around a horizontal axis running transversely of the dragging direction with an opening facing toward the bottom for taking up bottom material dislodged by a lower edge of the visor. The dredging head also comprises a discharge device for the dislodged bottom material. This discharge device comprises an inlet for the bottom material connecting to the opening of the visor and at least one outlet which is configured such that during movement in the dragging direction the bottom material can be discharged to at least one lateral side of the formed trench. Also described are a dredging vessel equipped with the dredging head, and a method for forming a trench in an underwater bottom.

摘要： The invention relates to a dredging head (6) of a trailing hopper dredger (1) which is configured to move in a direction of movement P. The dredging head (6) comprises a tubular construction (7) which can be attached to a suction line (3) and a visor (9) which is rotatable with respect to the tubular construction (7) and has a suction opening which is directed to the bottom for sucking in the bed material. The dredging head (6) further comprises a crushing device (12a, 12b, 16, 17, 18) for crushing material which is present in the dredging head (6). By means of the dredging head, it is possible to efficiently dredge bed material and in particular bed material containing rocks. The invention also relates to a dredging vessel equipped with the dredging head, and to a method for dredging a bed containing rocks.

摘要： Described is a suction head of a dredging vessel configured for movement in a dragging direction P. The suction head comprises a connecting construction connectable to a suction conduit and a visor rotatable relative to the connecting construction between a lowered and a raised position around a shaft running transversely of the dragging direction P and having a suction opening directed toward the bottom for suctioning up bottom material dislodged by a lower edge of the visor. The suction head is also provided with a precutting device and with positioning means configured to carry a lower edge of the precutting device to a greater depth than the lower edge of the visor in the raised position of the visor so that bottom material can be dislodged with the lower edge of the precutting device. Also described are a dredging vessel equipped with the suction head and a method for dredging an underwater bottom.

摘要： The invention relates to a suction head (6) for a dredging vessel (1). The suction head comprises a construction (7) provided on the bottom side with a suction opening and having a connection for a suction conduit (3) of the dredging vessel (1) and a visor (81) rotatable around a shaft (9) running transversely of the direction of movement (P) between a lowered and a raised position, wherein a curved wall part (8a) of the visor (81) is slid in substantially watertight manner along a wall part (7c) of the suction head (6). The visor (81) is further provided on the bottom side thereof with a toothed beam (10) with cutting tools (11) for penetrating the bottom, and with an opening (15) in its rear wall (8b) along which surrounding water can flow into the suction head (6) and which can be closed to the surrounding water by means of a closing member (20). Bottom material, and in particular bottom material comprising clay, can be dredged in efficient manner using the suction head (6). The invention also relates to a dredging vessel (1) equipped with the suction head (6) and a method for dredging a bottom particularly comprising clay.
