SCOURING-PREVENTION DEVICE, FOUNDATION STRUCTURE FOR OCEAN WINDMILL AND CONSTRUCTION METHOD
To provide a scouring-prevention device, a foundation structure for an ocean windmill and a construction method which can prevent overflow due to waves and tidal currents during construction.SOLUTION: A scouring-prevention device 10 that is provided so as to prevent scouring in a ground 12 around a structure 14 installed at a sea bottom, a river bottom or a lake bottom includes: a first bag body 16 which is annularly arranged on the ground 12 around the structure 14, is packed with a filter material 20 having a predetermined particle size, has a net shape and is flexible; and second bag bodies 18 which are arranged so as to be adjacent to each other or partially overlap each other in a circumferential direction along the first bag body 16 while being adjacent to or partially overlapping the radial outside of the first bag body 16, are packed with a filter material 20 having a predetermined particle size, have net shapes and are flexible.SELECTED DRAWING: Figure 1
【課題】施工中の波浪や潮流による流出を未然に防止することができる洗掘防止装置、洋上風車用基礎構造および施工方法を提供する。【解決手段】海底、河底または湖底に設置される構造物１４の周囲の地盤１２において洗掘を防止するために設けられる洗掘防止装置１０であって、構造物１４の周囲の地盤１２上に環状に配置されるとともに、内部に所定の粒度のフィルター材２０が詰め込まれた網目状の可撓性の第一袋体１６と、第一袋体１６の径方向外側に隣接または一部重複しつつ、第一袋体１６に沿う周方向に互いに隣接または一部重複して複数配置されるとともに、内部に所定の粒度のフィルター材２０が詰め込まれた網目状の可撓性の第二袋体１８とを備えるようにする。【選択図】図１
