PURPOSE:To efficiently and easily perform the gravel leveling and consolidation of seabed by fitting a steel pipe having a weight at its lower end and a vibrator on its upper end into the slide guide of a regulatively inclinable tower whose lower end is pivotally attached to the hull and the intermediate portion is supported by a reciprocally movable rod. CONSTITUTION:A tower 2 having a vertically slidable guide on its front, a hull 1 pivotally attached to its lower end, and a reciprocally movable rod 4 of the hull 1 supporting its intermediate portion is provided. Also, the tower 2 has a weight 5 on its lower end and a vibrator with a vibrohammer 7 on its upper end, and said vibrator of the steel pipe 6 leading to the sea surface from the seabed is fitted into the slide guide of the tower 2. The charged gravel group is leveled and consolidated by operating a wire rope 8 connected to a winch 10 through a pulley 9 and by the vibration of the hammer 7. |
