うになった。As described above, according to the present invention, a dredging device is rotatably attached to the tip of an arm provided on a barge capable of swinging left and right, and a dredge device is provided between the dredging device and the arm. A pair of hydraulic cylinders are arranged in a C-shape, and the dredging device is intermittently rotatable by 90 ° so that the two hydraulic cylinders can be rotated without checking the position by a sensor or the like. Depending on the force balance, the dredging device can be set to an intermediate position (a position facing the front of the barge) and can be set to the left or right by extending either hydraulic cylinder. As a result, at the turning points at the left and right ends of the swing of the dredging device, when the dredging device is advanced one pass by the width thereof, the sludge in front can be dredged.
