GRAB DREDGE CONSTRUCTION SUPPORT DEVICE AND DREDGE METHOD

PROBLEM TO BE SOLVED: To provide a grab dredge construction support device and a dredge method capable of easily dredging flat a water bottom in a dredged area. SOLUTION: The delivered in and out amount of a supporting wire 6 is detected by a supporting wire delivery meter 17, and the delivery in and out amount of an opening/closing wire 7 is detected by an opening/closing wire delivery meter 18. Based on the detected data, the edge position A of a bucket in the side direction is calculated by a data processor 21, and the moving route of the edge position A in the side direction of the bucket calculated by the data processor 21 is graphically displaced in real time on a display device 20. Since the dredge is performed while allowing an operator to know the moving route, the edge position A can be adjusted so as to move horizontally based on the moving route of the edge position A to easily dredge the water bottom in a flat shape.
