Abstract
PURPOSE: To construct a thrown stone mound rapidly and correctly by separately constituting the chute installed on the hull for throwing away stones and the levelling apparatus for the thrown stones.
CONSTITUTION: In case of forming a thrown stone mound 6 on the sea bottom, a chute 2 is raised and lowered through a pulling member 4 by operating the winch on a hull 1, and the lower end of the chute 2 is positioned at a prescribed depth of water. A thrown stone levelling device 5 is set on the thrown stone mound 6 which is constructed at the standard levelling height, and the gate 9 is driven by a driving device 8 and opened. A pilot hammer 7 is operated, and the thrown stones are put into a hopper from a gat ship by pulling the levelling device 5 through a pulling member 13, and the sotnes are thrown away onto the sea bottom through the chute 2. In this state, the thrown stones are levelled by the levelling device 5 and rolled with sufficient pressure, and the turning of the gate 9 is controlled to form the mound 6 having a prescribed height.
