Next, the barge is moved by the above-mentioned one stroke, and similar dropping is sequentially performed.

[0005]

In such a conventional apparatus, as shown in FIG. 6, a fan-shaped object layer a is sequentially formed for each movement of the barge 1; For example, in the case of forming a rubble mound, it is difficult to form both edges of the mound neatly, and when throwing rubble or sanding a wide area, it is difficult to make the whole a uniform thickness. .

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a seabed loading apparatus for rubble stones and the like which can easily manage scattered tracks and has high workability and work efficiency.

[0007]

A feature for solving the above-mentioned conventional problems and achieving the intended object is that the tip is projected above the water from the dropping edge of the barge, and is positioned on the width direction side. A dropping conveyor that moves in parallel and is movable in the longitudinal direction;
An intermediate conveyor whose tip swings in an arc direction in accordance with the parallel movement of the drop conveyor and supplies the drop onto the drop conveyor, and a drop which supplies a fixed amount of the drop to the swing center of the intermediate conveyor. There is a seabed loading device such as a rock stone equipped with a fixed quantity supply device. In addition, the drop conveyor is on the barge,
On a traversing carriage that moves in the width direction of the conveyor, movably supported in the longitudinal direction, and, on the traversing carriage, a forward and backward moving carriage movably in the longitudinal direction of the dropping conveyor is provided.
It is preferable to connect the front end of the intermediate conveyor to the front-rear trolley.

[0008]

In order to use the seabed loading device of the present invention, the barge is fixed with an anchor or the like, and the dropping conveyor is reciprocated in the width direction. While retreating one by one, a fixed amount of rubble stone or scattered sand is supplied onto a conveyor and dropped into the sea. This is performed continuously for one stroke in the longitudinal direction of the dropping conveyor. This forms a rectangular scatter on the sea floor. Next, the barge is moved by the one stroke, and the drop conveyor is advanced in the protruding direction to perform the same sea floor drop. This is sequentially repeated to form a band-shaped object layer, and when it is necessary to spread in the width direction, the seabed is sequentially dropped along the band-shaped object layer that has been constructed earlier.
