BUBBLE TYPE WATER POLLUTION PREVENTION FENCE
To provide a bubble type water pollution prevention fence allowing an installation operation and a removal operation of a sink-and-float belt to be easily performed in a short time.SOLUTION: A bubble type water pollution prevention fence 10 is provided with: a tube type sink-and-float belt 20 on which a heavy weight 23 is integrally attached; and an air-water supplying device 30 selectably supplying air or ballast water to the sink-and-float belt 20, wherein the sink-and-float belt 20 is provided with an air diffusing passage 21 and a buoyancy adjustment passage 22 to generate bubble through continuously supplying air to the air diffusing passage 21 and to allow buoyancy adjustment of the sink-and-float belt 20 through supplying air or ballast water to the buoyancy adjustment passage 22.SELECTED DRAWING: Figure 2
【課題】浮沈帯の設置作業と撤去作業を短時間のうちに簡単に行える、気泡式水質汚濁防止フェンスを提供すること。【解決手段】重錘２３が一体に付設されたチューブ状の浮沈帯２０と、浮沈帯２０に対してエアまたはバラスト水を択一的に供給可能な気水供給装置３０とを具備する気泡式水質汚濁防止フェンス１０であって、浮沈帯２０は散気路２１と浮力調整路２２とを具備していて、散気路２１へエアを連続供給することで気泡が発生し、浮力調整路２２へエアまたはバラスト水を供給することで浮沈帯２０の浮力調整が可能である。【選択図】図２
