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: A gravity foundation 4 is produced so that a direct foundation 3 and a concrete tower 7 with windmill tower installed on the top is constructed integrally using concrete in a land yard 1. The gravity foundation 4 is towed and transported to the installation site and sunk and installed on bedrock 22 on the seabed. Subsequently, an inside 9 of the concrete tower 7 is filled with a filling material 37-1, and a hollow portion 5 of the direct foundation 3 is filled with filling sand 37-2. The direct foundation 3 and concrete tower 7 are fixed to the bedrock 22 on the seafloor by a ground anchor 31, which penetrates through the inside of the concrete tower 7 with one end fixed to the bedrock 22 and the other end fixed to the fixing plate 15 formed on the sea part of the concrete tower 7.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】直接基礎３と、上部に風車タワーが設置されるコンクリートタワー７とを、コンクリートを用いて陸上ヤード１で一体として重力式基礎４を製作し、現場まで曳航して運搬し、海底の岩盤２２上に沈設する。次に、コンクリートタワー７の内部９に中詰め材３７−１を充填し、直接基礎３の空洞部５に中詰め砂３７−２を充填する。直接基礎３及びコンクリートタワー7は、コンクリートタワー７の内部を貫通し、一端が岩盤２２に定着され、他端がコンクリートタワー７の海上部分に形成された定着板１５に定着されるグランドアンカー３１によって、海底の岩盤２２に対して固定される。【選択図】図５
