CONSTRUCTION METHOD OF BASE STRUCTURE AND BASE STRUCTURE
To provide a construction method of a base structure for on-water facilities allowing installation using an existing floating crane without requiring a huge barge type platform and without requiring a temporary support base.SOLUTION: A construction method is provided with: a straight pile installation step of vertically installing a straight a pile 3 in a water bottom ground G directly below on-water wind power generation facilities 1; a template installation step of installing a template structural body 5 at a position equal to or higher than a height of a water level on an upper part of the straight pile 3; an oblique pile installation step of installing an oblique pile 4 oblique to the straight pile 3 in the water bottom ground G; and an oblique pile fixing step of fixing an upper part of the oblique pile 4 on the template structural body 5. The oblique pile installation step includes limiting an installation direction of the oblique pile 4 with a guide member 52 formed on the template structural body 5, and the oblique fixing step includes fixing the oblique pile 4 on the guide member 52.SELECTED DRAWING: Figure 2
【課題】大規模な台船を要することなく既存の起重機船を使用しての施工が可能で、仮支承台を要することなく施工することが可能な水上施設用基礎構造の施工方法を提案する。【解決手段】洋上風力発電施設１の直下の水底地盤Ｇに直杭３を鉛直に打設する直杭打設工程と、直杭３の上部の水面以上の高さ位置にテンプレート構造体５を設置するテンプレート設置工程と、直杭３に対して傾斜した斜杭４を水底地盤Ｇに打設する斜杭打設工程と、斜杭４の上部をテンプレート構造体５に固定する斜杭固定工程とを備えている。斜杭打設工程ではテンプレート構造体５に形成されたガイド部材５２によって斜杭４の打設方向を規制し、斜杭固定工程ではガイド部材５２に斜杭４を固定する。【選択図】図２
