DREDGING CONTROL SYSTEM AND DREDGING METHOD
To provide a dredging control system and a dredging method capable of more securely avoiding work for re-performing dredging caused by remaining excavation in dredging work using a pump dredger.SOLUTION: A controller 14 calculates three-dimensional position information on an excavation part 5 based on three-dimensional position information on a ship body 2 of a pump dredger 1 and information on an inclination angle of a ladder 4, and based on the calculated three-dimensional position information on the excavation part 5, planned dredging soil amount map data specifying a planned dredging soil amount for each section of a water bottom B, and measurement data on a sediment suction amount sucked by suction means 7 that is measured by sediment suction amount measurement means 13, controls at least either one of the swing speed of the ship body 2 and the ladder 4 by swing means 9 or the rotation speed of a cutter 5a, a component of the excavation part 5, so that a difference between a planned dredging soil amount of a section being excavated by the excavation part 5 and a sediment suction amount to be sucked by the suction means 7 in the section becomes within a preset allowable range.SELECTED DRAWING: Figure 1
【課題】ポンプ浚渫船を使用した浚渫作業における掘り残しによる浚渫をやり直す作業をより確実に回避できる浚渫制御システムおよび浚渫方法を提供する。【解決手段】制御装置１４により、ポンプ浚渫船１の船体２の三次元位置情報と、ラダー４の傾斜角度の情報とに基づいて掘削部５の三次元位置情報を算出し、その算出した掘削部５の三次元位置情報と、水底Ｂの区画毎の計画浚渫土量を定めた計画浚渫土量マップデータと、土砂吸入量計測手段１３により計測した吸入手段７により吸入した土砂吸入量の計測データとに基づいて、掘削部５が掘削している区画の計画浚渫土量と、その区画で吸入手段７によって吸入する土砂吸入量との差分が予め設定された許容範囲内となるように、旋回手段９による船体２およびラダー４の旋回速度、または、掘削部５を構成するカッター５ａの回転速度の少なくともいずれかを制御する。【選択図】図１
