Abstract
PURPOSE:To improve working efficiency by arranging a chute which is connected with a stone throwing in hopper facing freely upward and downward and equipped with holder having thrown-stone levelling claw at the top end. CONSTITUTION:Stone is thrown into a hopper 6. The thrown stone falls down onto the sea bottom through the hopper 6, chute 8 connected with the hopper, and the top end hopper 9 of the chute 8. Stone throwing operation is repeated, and the level of the surface of the stone thrown is contacted with the thrown-stone levelling claw 10 of the holder 9. Then, a rack base 4 is turned by one pitch in the righr and left direction, and the holder at the top end of the chute is allowed to follow the rack base and turn, thus throwing operation is performed. After that, the rack base is travelled along on the ship, and stone-throwing operation is repeated, then the work is completed. Thus, the thrown-stone feeding amount and the shift of the holder for the hopper is controlled, and the mound area can be finished at a proper height.
