FOUNDATION STRUCTURE FOR OFFSHORE WIND POWER GENERATION AND CONSTRUCTION METHOD OF FOUNDATION STRUCTURE FOR OFFSHORE WIND POWER GENERATION
To provide a foundation structure for offshore wind power generation and a construction method of foundation structure for offshore wind power generation capable of reducing the construction period and construction cost by greatly reducing the size of the gravity foundation installed on the seabed.SOLUTION: An outer shell 5 with a transition piece 9 fixed and transport is towed to the site and is submerged on bedrock 1 on the seabed, and the outer shell 5 is filled with concrete 19; thereby a direct foundation 21 is installed on the bedrock 1. Subsequently, on the direct foundation 21, a tower 23, which is a substructure of an offshore wind power on which a windmill tower 47 is to be installed, is installed. Then, a ground anchor 39 is placed by using a guide hole 35 of a fixing plate 25 formed on the sea part of the tower 23 and a sheath pipe 11 embedded in the direct foundation 21 as a guide and an anchor body 37 is formed on the bedrock 1 and the lower end of the ground anchor 39 is fixed. A fixing tool 41 is attached and the upper end of the ground anchor 39 is fixed to the fixing plate 25.SELECTED DRAWING: Figure 5
【課題】海底に設置される重力式基礎を大幅に小型化して工期および工費を縮減できる洋上風力発電用基礎構造および洋上風力発電用基礎構造の施工方法を提供すること。【解決手段】トランジションピース９が固定された外殻５を曳航して現場まで運搬して海底の岩盤１に沈設し、外殻５内にコンクリート１９を充填することにより、岩盤１上に直接基礎２１を設置する。次に、直接基礎２１上に、上部に風車タワー４７が設置される洋上風力発電の下部構造体であるタワー２３を設置する。そして、タワー２３の海上部分に形成された定着板２５のガイド孔３５と直接基礎２１に埋設された鞘管１１とをガイドとしてグランドアンカー３９を打設し、岩盤１にアンカー体３７を形成してグランドアンカー３９の下端を定着し、定着具４１を取り付けてグランドアンカー３９の上端を定着板２５に定着する。【選択図】図５
