Abstract
The invention discloses a composite pile foundation for offshore wind power. The composite pile foundation comprises at least three composite piles (10) and a spider (19). Each composite pile is divided into an upper pile section (11) and a lower pile section (12), the upper pile section (11) is a steel pipe pile or a prestress concrete pipe pile at least partially wrapped by a steel pipe, and the lower pile section (12) is a prestress concrete pipe pile. Steel leg drums (20) with the number corresponding to that of the upper pile sections (11) are arranged on the spider (19), and each upper pile section (11) penetrates a corresponding steel leg drum to be fixed with the steel leg drum. A construction method of the composite pile foundation for offshore wind power is further disclosed. Compared with common large-diameter steel pipe piles, the composite pile foundation has the advantages of being reasonable in structure, better in pile foundation selectivity and capable of giving full play to advantages of the steel pipe piles and the prestress concrete pipe piles and saving steel materials. Meanwhile, the pile foundation is low in construction device requirement, wide in selectivity, small in offshore construction difficulty and better in total economy.
