FOUNDATION OF WATER SURFACE WIND POWER GENERATION DEVICE

摘要

PROBLEM TO BE SOLVED: To manufacture foundation of a water surface wind power generation device at low cost in a foundation of a wind power generation device installed on water surface such as on the sea or on a lake.

SOLUTION: This foundation of the water surface wind power generation device consists of steel pipe pile 1 arranged at each apex of a regular polygon in a plan view and driven in sea bottom and a steel structure stand 2 fixed by covering a pile head of each steel pipe pile 1 and supporting a base end part 4a of a strut 4 of a wind power generation part 3 with positioning the same at a center of the regular polygon. The steel structure stand 2 consists of steel pipe pole 2a fixed by covering the pile head of the steel pipe pile by a lower end thereof, a pole connection member 2A horizontally connecting upper and lower end of adjoining steel pipe poles 2a and obliquely connecting the upper end and the lower end, and a support member 2B connecting and supporting the base end part 4a of the strut 4 of the wind power generation part and the steel pipe pole 2a or the pole connection member 2A.
