OCEAN OPENING-CLOSING TYPE TURBID WATER DIFFUSION PREVENTING FENCE

摘要

PURPOSE:To prevent the breakage of a fence by a method in which one side of a sheet is formed detachably with a holder in a fence unit formed by mooring the holders floating on sea and providing the sheet between the holders. CONSTITUTION:One end of each of mooring ropes 2a and 2b is coupled with a holder 1 consisting of a column 1a and a head 1b and the other end is connected with a sinker 2c for mooring. A sheet 3b is provided between the holders 1 to form a fence unit 3. One or more fence units 3 are connected for setting. The sheet 3b is designed to be detached at least at one side with the holder 1 by a detaching means 4. The units 3 are opened when great waves come to relieve the force of waves, permitting the strength of the fence to be reduced and the size of mooring device to be miniaturized.
