PROBLEM TO BE SOLVED: To provide a foundation structure which is suitable for installation in a shallow sea area. SOLUTION: The foundation structure is comprised of a cylindrical member 11, four first pallets 13, second pallets 14, a closed-end concrete cylindrical member 15, and a foundation tube 17 for an aerogenerator. The cylindrical member has collar portions 11a and 11b on external and internal peripheral portions thereof. Each first pallet 13 has one end thereof 13a mounted on the external collar portion 11a of the cylindrical member 11 so as to cover the same and the other end thereof 13b radially spread. Each second pallet 14 is mounted on the first pallets 13 so as to press the same from above. The concrete cylindrical member 15 is fitted into the cylindrical member 11, and the foundation tube 17 is fitted into the concrete cylindrical member 15. The cylindrical member 11, a portion of each first pallet 13 exclusive of the one end 13a, and a rear surface of a peripheral portion of each second pallet 14 have projections, respectively, which can engage with submarine geology. Further, a workbench 16 is mounted on an upper edge of the concrete cylindrical member 15. By virtue of this construction, installation work can be safely, easily, and positively carried out. Further, positional preservation of the foundation structure after the installation is stabilized, to thereby facilitate inspection of the wind turbine generator. |
