OFFSHORE WIND POWER GENERATION FOUNDATION SUBSTRUCTURE AND CONSTRUCTION METHOD OF OFFSHORE WIND POWER GENERATION FOUNDATION SUBSTRUCTURE
To provide an offshore wind power generation foundation substructure and a construction method of an offshore wind power generation foundation substructure that can reliably fix a jacket structure to a water bottom without driving a pile.SOLUTION: A jacket structure 1 having a plurality of legs 3 formed of hollow steel pipes and a connecting member 7 that connects the plurality of legs 3 is constructed on land. A bottom slab 5, which is a supporting portion, is attached to a lower end portion of the leg 3. Next, the jacket structure 1 is transported to the site and sunk, the bottom slab 5 is placed on a rock bed 19 at a bottom of the water, and the lower end of the leg 3 is supported by the bottom slab 5. Then, a ground anchor 25 is arranged so as to pass through an inside 29 of the leg 3 and penetrate the bottom slab 5, one end of the ground anchor 25 is fixed in the rock bed 19, the other end is fixed to a fixing plate 23 fixed to a portion above the water surface 21 of the leg 3, and the jacket structure 1 is fixed to the rock bed 19 by the ground anchor 25.SELECTED DRAWING: Figure 4
【課題】杭を打設せずにジャケット構造物を水底に確実に固定できる洋上風力発電用基礎の下部構造および洋上風力発電用基礎の下部構造の施工方法を提供すること。【解決手段】中空状の鋼管で形成される複数のレグ３と、複数のレグ３を連結する連結部材７とを有するジャケット構造物１を陸上で構築する。レグ３の下端部には支持部である底版５を取り付ける。次に、ジャケット構造物１を現場に運搬して沈設し、底版５を水底の岩盤１９上に配置して、レグ３の下端部を底版５で支持する。そして、グランドアンカー２５をレグ３の内部２９を通し底版５を貫通させて配置し、グランドアンカー２５の一端を岩盤１９内に定着させ、他端をレグ３の水面２１より上の部分に固定された定着板２３に定着させて、グランドアンカー２５によってジャケット構造物１を岩盤１９に対して固定する。【選択図】図４
