DREDGING CONTROL SYSTEM AND DREDGING METHOD
To provide a dredging control system and a dredging method capable of forming a smooth slope face on a water bottom while avoiding making dredging equipment be massive and thick.SOLUTION: When a slope face C2 is formed on a water bottom B, a turning speed at which a ladder 4 is to be turned vertically is set at a fixed turning speed. Then, a controller 13 calculates three-dimensional position information on an excavation part 5 provided at a tip of the ladder 4 based on three-dimensional position information on a ship body 2 of a pump dredger 1 and information on an inclination angle of the ladder 4, and based on the calculated three-dimensional position information on the excavation part 5, the information on the inclination angle of the ladder 4, and design depth map data on the slope face C2, controls a swing speed in a horizontal direction of the ship body 2 and the ladder 4 by swing means 9 so that a difference in height between a design depth L1 of the slope face C2 and a depth of excavation by the excavation part 5 becomes within a preset allowable range.SELECTED DRAWING: Figure 1
【課題】浚渫装備の重厚化を回避しつつ、水底に滑らかな法面を形成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】水底Bに法面C2を形成するときに、ラダー4を上下方向に回動させる回動速度を一定の回動速度に設定し、制御装置13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、ラダー4の先端に設けられた掘削部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、ラダー4の傾斜角度の情報と、法面C2の設計深度マップデータとに基づいて、法面C2の設計深度L1と掘削部5による掘削深度との高低差が予め設定し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の水平方向の旋回速度を制御する。【選択図】図1
