PURPOSE:To enable loaded earth and sand or the like to be dumped readily and safely by connecting with a main hull a subhull having a generally L-shaped cross section to cover the main hull from the one side to the upper surface thereof to turn and slant laterally. CONSTITUTION:A box-shaped main hull 1 is connected through a hinge 3 in the bottom to a subhull 2 having a generally L-shaped section covering the one side and the upper surface of the main hull. Cargos 4 are loaded on the upper surface of the subhull 2 and further the main hull 1 is connected to the subhull 2 through a cylinder 5. By operating this cylinder 5 to turn and incline the sub hull about the hinge 3 in the bottom of the sea, the cargoes 4 are dis carded. |
