POLLUTION PREVENTION DEVICE AND SUSPENSION METHOD OF POLLUTION PREVENTION DEVICE
PROBLEM TO BE SOLVED: To provide a pollution prevention device, easy in installation and removal, and capable of preventing damage of a film.SOLUTION: A pollution prevention device 1 comprises a first floating body 3 floated on a water surface, a film 2 suspended from the first floating body 3, a plate-like member 7 for covering the water bottom under the film 2 and a restriction member 6 suspended from the water surface on one surface side and the other surface side of the film 2, connecting the lower end to the plate-like member 7 and restricting a movable range of the film 2 in the water above the plate-like member 7. When installing or removing the pollution prevention device 1, at least the first floating body 3, the film 2 and the restriction member 6 are placed on the plate-like member 7, and the plate-like member 7 is suspended.SELECTED DRAWING: Figure 4
【課題】設置や撤去が容易で、且つ、膜の破損を防ぐことのできる汚濁防止装置を提供すること。【解決手段】汚濁防止装置１は、水面に浮かべられる第一浮体３と、第一浮体３から吊り下げられる膜２と、膜２の下方の水底を覆う板状部材７と、膜２の一面側と他面側とにおいて水面から垂下され、下端が板状部材７に連結され、水中における膜２の可動範囲を板状部材７の上方に制限する制限部材６とを備える。汚濁防止装置１を設置又は撤去する場合に、少なくとも第一浮体３と膜２と制限部材６とを板状部材７に載せて板状部材７を吊り上げる。【選択図】図４
