Abstract

PURPOSE:To effectively correct the uneven portion of leveled ground under water by pivotally providing plural tamping rollers to a base frame whose front side is provided with a keep plate. CONSTITUTION:An under-water leveler a is hung down to the top end of a rubble-mound 37 under water by means of a crane 31 and dragged by a tug boat 29. The convexed portion of the top end is pushed away by a keep plate 9, and an inside roller 23 is moved back and forth by inertia in the central portion 18 to raise its tamping effect, because tamping rollers 11-13 are moved with non-uniform speeds resulting from somewhat retardation of their advancing speeds due to the tidal resistance of the tug boat 29, the loosening of wire ropes 34 and 36, and the unevenness of the top end portion. Also, since a steel netting 28 formed of chains is dragged on the top end portion, the remaining convexed portion can be leveled.
