PURPOSE:To raise the accuracy of construction of leveling stone mound by a method in which a leveling stone supplying chute attached to a reference scale having a detachable plate on its leg portion is moved and leveling stones are discharged while operating a vibro-compactor to construct a leveling stone mound. CONSTITUTION:A plate 4 is detachably provided to the leg 1b of a reference scale 1 having the expandible leg 1b on the lower part of its frame 1a, and a vibro-compactor 3 is connected provided on the one side of moving direction in the leveling stone supply chute 2 movably set on the frame 1a. The scale 1 is landed on a given botton under water and adjusted horizontaly at a desired height, the chute 2 is moved from a given position to the opposite direction of the compactor 3 side, and leveling stone 8 are discharged to construct a leveling stone mound while vibrationally compacting it by the compactor 3. In case where the plate 4 is buried in the mound, the plate 4 is removed out and it is left behind, and also when the plate 4 is not buried, it is moved to the next position with the leg 1b. |
