OIL FENCE, CONSTRUCTION METHOD OF OIL FENCE AND METHOD FOR PREVENTING FLOATING MATTER FROM FLOWING OUT
PROBLEM TO BE SOLVED: To provide an oil fence capable of preventing a floating matter flowing down in a running water area from flowing out to a downstream side.SOLUTION: An oil fence 30 for preventing a floating matter 50 flowing down in a running water area from flowing out to a downstream side is provided with: (1) a water shut-off fence 31 having an underwater soaked part 31a soaked in the water at a predetermined waterline D, and arranged along a transverse direction in the running water area in such a condition that at least an upstream side face 31aof the underwater soaked part 31a is substantially perpendicular to the water surface; and (2) a drawing flow generation area coating member 32 arranged along the water shut-off fence 31 at an upstream part of the water shut-off fence 31 and covering a water surface of a drawing flow generation area γ at the upstream part of the water shut-off fence 31 in a belt-like shape along the water shut-off fence 31.SELECTED DRAWING: Figure 3
【課題】流水域を流下してくる浮遊物を下流側に流出しにくくすることのできるオイルフェンスを提供する。【解決手段】流水域を流下する浮遊物５０が下流側へ流出しにくくするためのオイルフェンス３０を、（１）所定の喫水Ｄ１で水中に浸漬される水中浸漬部３１ａを有し、少なくとも水中浸漬部３１ａの上流側面３１ａ１が、水面に対して略垂直となる状態で流水域の横断方向に沿って配される遮水フェンス３１と、（２）遮水フェンス３１の上流部で遮水フェンス３１に沿って配され、遮水フェンス３１の上流部における引き込み流発生領域γの水面を、遮水フェンス３１に沿った帯状に覆う引き込み流発生領域被覆部材３２とを備えたものとした。【選択図】 図３
