Abstract
PURPOSE: To reduce resistance against water when it is not in use and to facilitate towing by a dredging boat by a method wherein a pollution dispersion prevention film is equipped so as to be wound up for a float.
CONSTITUTION: A self floating type pollution dispersion prevention frame A consists of a small film material 2 of a loop type nonpermeability or of a small permeability coefficient, and a weight member 3; and is lowered to be constructed into water from a float A. Several places of the float 1 are attached with blocks 7 and a wire 8 fed out of a winch 9 installed on a dredging boat B is wound up by the block 7 to be lowered. And the lower terminal of the wire is connected to a weight 3. When the wire 8 is wound up by the operation of the winch 9, shape reserving materials 6 approach one another and a film material part 2 between them becomes like a pleat, thus, the vertical width of the film material 2 is adjusted.
