DREDGING MANAGEMENT SYSTEM AND DREDGING MANAGEMENT METHOD

摘要

To perform pump dredging with high accuracy regardless of operators' skills and experiences.SOLUTION: A dredging management system 10 includes: position measuring means 12 that measures the position of a pump dredging ship 36; a sea level gauge 18 that measures the sea level near a work range; a plurality of sensors 14 that measure the attitude of the pump dredging ship 36; calculation management means 24 that performs calculation for the position and depth of a cutter based on these measurement results; display means 26 that displays information handled by the calculation management means 24; and control means 28 that controls a ladder winch 44 and adjusts the depth of the cutter based on the position and depth of the cutter that are calculated by the calculation management means 24, and a cutter management depth that is set in the calculation management means 24. With this configuration, the ladder depth can be adjusted in real time according to the cutter management depth. Therefore, it is possible to dredge a water bottom according to a designed dredging depth, and perform pump dredging with high accuracy.SELECTED DRAWING: Figure 1
