SCOUR PREVENTION STRUCTURE AND CONSTRUCTION METHOD FOR SCOUR PREVENTION STRUCTURE
To provide a scour prevention structure which is easy to manufacture and arrange and which can reduce a flow speed on a water bottom surface and capture sand particles, and a construction method for the scour prevention structure.SOLUTION: A scour prevention structure 3 installed around a monopile 2 is constructed in such a manner that, after arranging a frame member 4 and protrusion members 5 around an installation scheduled part of the monopile 2, at the installation scheduled part of the monopile 2 surrounded with the frame member 4, the monopile 2 is installed by providing a gap 17 between the monopile and the frame member 4. The frame member 4 is arranged substantially radially around the monopile 2. The protrusion members 5 are a plurality of flat plate-like members, and fixed to the frame member 4 so as to surround the monopile 2. In a vertical direction cross section, the upper end side of the protrusion member 5 is inclined to the monopile 2 side, and the heights of the plurality of protrusion members 5 arranged having an interval from the monopile 2 side are not identical.SELECTED DRAWING: Figure 1
【課題】製作や配置が容易で、水底面の流速を低減して砂粒子を捕捉できる洗堀防止構造および洗堀防止構造の施工方法を提供する。【解決手段】モノパイル２の周囲に配置される洗堀防止構造３を、モノパイル２の設置予定部の周囲に枠部材４と突起部材５とを配置した後、枠部材４で囲まれたモノパイル２の設置予定部に、枠部材４との間に隙間１７を設けてモノパイル２を設置して施工する。枠部材４は、モノパイル２の周囲に略放射状に配置される。突起部材５は、複数の平板状の部材であり、枠部材４に固定されてモノパイル２を囲むように配置される。鉛直方向断面において、突起部材５の上端側はモノパイル２側に傾斜しており、モノパイル２側から間隔をあけて配置された複数の突起部材５の高さは同一ではない。【選択図】図１
