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

    【課題】オペレータの技量や経験の如何に関わらず高精度にポンプ浚渫を行う。【解決手段】浚渫施工管理システム10は、ポンプ浚渫船36の位置を計測する位置計測手段12と、施工範囲近傍の潮位を計測する潮位計18と、ポンプ浚渫船36の姿勢を計測する複数のセンサ14と、これらの計測結果に基づいてカッターの位置及び深度の算出等を行う演算管理手段24と、演算管理手段24により取り扱う情報を表示する表示手段26と、演算管理手段24により算出されたカッターの位置及び深度並びに演算管理手段24に設定されたカッター管理深度に基づいて、ラダーウィンチ44を制御してカッターの深度を調整する制御手段28と、を含んでいる。このような構成により、カッター管理深度に従ってリアルタイムにラダーの深度を調整することができるため、水底を設計浚渫深度通りに浚渫することができ、高精度にポンプ浚渫を行うことが可能となる。【選択図】図1
