To provide a dredger with a pump and a pump dredging method capable of dredging a planned dredging zone in a rectangular shape with high accuracy.SOLUTION: A dredger 1 with a pump can dredge a planned dredging zone in a rectangular shape with high accuracy to move a work ship 2 forward and backward with forward and backward means 12 during turning based on a travelling amount k calculated by calculation means and to dredge up mud as moving a cutter head 5 along a predetermined track, while control means is provided with the calculation means calculating the traveling amount of the work ship and a rudder depth based on information from position measurement means and information on the planned dredging zone.SELECTED DRAWING: Figure 3

    【課題】矩形状の計画浚渫区域を高精度で浚渫することができるポンプ浚渫船及びポンプ浚渫方法の提供【解決手段】ポンプ浚渫船1は、制御手段は、位置計測手段からの情報と計画浚渫区域情報とに基づいて作業船の移動量とラダー深度を算出する演算手段を備え、演算手段によって算出された移動量kに基づいて前後進手段12によって作業船2を旋回中に前後進させ、カッターヘッド5を所望の軌跡に沿って移動させつつ掘削するようにし、矩形状に区画された計画浚渫区域を高精度で浚渫することができある。【選択図】図3
