Abstract
PURPOSE: To receive the return of wave at the low tide and to restrain the abrasion movement of the pollution prevention film against the sea bottom face by a method wherein a water breaking stockade is constructed at one side of the tidal current at the sea bottom part in the installation place of a pollution dispersion prevention film.
CONSTITUTION: In case a dredging operation is performed in a comparatively shallow sea area such as a harbon et al, a silt protector 3 made of a film material 2 of nonpermeability is lowered from a float 1 at the outer circumference of the construction works area. At least, on one side of the tidal current direction at a place of the corresponding protector 3 installation, a water breaking stockade 4 such as a wooden stockade is constructed so that the upper end thereof may rise a little higher than the water level at the low tide. Therewith, pollution is prevented from run-off and dispersion by means of the protector 3 at the high tide and wave return is obstructed with the stockade 4 at the low tide to prevent pollution from run-off and dispersion as well as to restrain the abrasive movement and abrasive damages of the protector 3 against the sea bottom face.
