METHOD FOR CONSTRUCTING FOUNDATION STRUCTURE FOR WIND POWER GENERATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method for constructing a foundation structure for a wind power generation system which supports a strut extending from the surface of the sea to the vicinity of the seabed while supporting the wind power generation system on the sea, capable of improving the bearing capacity and durability of the foundation structure.

SOLUTION: The condition of the seabed 200 and the condition of tidal currents near the seabed 200 are investigated in advance to examine the number of filter units 50 and the position where the filter units 50 are to be installed. Then, piles 12b as a base of the foundation structure are provided so as to be supported by a bearing layer. A plurality of filter units 50 are installed in close contact with each other between the seabed 200 and each pile 12b. Then, a formwork 12e for a base slab portion 12a is installed on the upper ends of the piles 12b. Concrete is placed in the formwork 12e to form the base slab portion 12a. Then, the strut 11 is fixed to the upper end of the base slab portion 12a.
