POLLUTION PREVENTION FILM
PROBLEM TO BE SOLVED: To provide a pollution prevention film that hardly causes coarse surface even if a sea bottom foundation at an installation site is a reef.SOLUTION: A pollution prevention film 10 is installed in vertical direction underwater. A chain-like weight 14 is installed in vertical direction from a lower part of the film 13 upward. The chain-like weight 14 is installed at multiple positions at intervals in horizontal direction. The chain-like weight 14 is attached to a film body using a holder 35 that passes through a central hole on an annular body constituting a chain 33.SELECTED DRAWING: Figure 1
【課題】設置個所の海底の地盤が岩礁である場合などにおいても引っ掛かりが発生しにくい汚濁防止膜を得る。【解決手段】水中において上下方向に設置される汚濁防止膜１０である。膜１３の下部から上側に向けて、鎖状の重錘１４が上下方向に設置される。鎖状の重錘１４は、水平方向に間隔をおいた複数の位置に、それぞれ設置される。鎖状の重錘１４は、鎖３３を構成する環状体の中央孔を通るホルダ３５を用いて、膜体に取り付けられる。【選択図】図１
