SCOURING PREVENTION CONSTRUCTION METHOD OF PILE FOUNDATION
To provide a scouring prevention construction method of a pile foundation allowing installation of scouring prevention measures in low cost and a short period without using a large amount of debris, blocks, and bagged bodies around a bottom part of the pile foundation settled in a water bottom.SOLUTION: A scouring prevention construction method for this pile foundation comprises the steps of: installing a cylindrical body 11 comprising sheet material 20 having an inner diameter larger than an outer diameter of a pile so as to surround a pile 10 installed in a water bottom and having elasticity; reducing a diameter of an upper end part of the cylindrical body so as to contact the upper end part of the cylindrical body with the pile over the whole periphery by sinking the cylindrical body in water; and installing the sheet material at least in a range corresponding to an inner diameter of the cylindrical body around the pile on a water bottom surface.SELECTED DRAWING: Figure 2
【課題】水底に打設された杭基礎の底部周囲において大量の捨石やブロックや袋詰体を使用せずに低コストかつ短い工期で洗掘対策工を設置可能な杭基礎の洗掘防止工法を提供する。【解決手段】この杭基礎の洗掘防止工法は、水底に打設された杭１０に杭を包囲するように杭の外径よりも大きい内径を有しかつ可撓性のあるシート材２０からなる円筒状体１１を設置し、円筒状体を水中沈降させ、円筒状体の上端部が全周に渡って杭に接するように円筒状体の上端部を水中施工機械により縮径し、水底面においてシート材を杭の周囲で少なくとも円筒状体の内径に相当する範囲内に敷設する。【選択図】図２
