Title:
OFFSHORE WIND POWER SINGLE PILE-FRICTION WING COMPOSITE FOUNDATION AND CONSTRUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/174572
Kind Code:
A1
Abstract:
An offshore wind power single pile-friction wing composite foundation and a construction method therefor. The offshore wind power single pile-friction wing composite foundation comprises a single pile and a friction wing. The friction wing is connected to the single pile by means of a force transmission pipe; a conical transition section of the single pile goes deep into a seabed bearing stratum; the force transmission pipe of the friction wing located in the bearing stratum is in close contact with the conical transition section of the single pile; side wings of the friction wing are connected to the outer wall of the force transmission pipe; and each ring wing is provided in the included angle of the side wings. According to the present invention, the friction wing is of a through structure in the axial direction, such that the friction wing can conveniently penetrate through a seabed sludge layer to be embedded into the bearing stratum; the side wings, the ring wings, and the force transmission pipe support one another, thereby facilitating maintenance of the structural stability of the friction wing; a soil arching effect is generated between the side wings and the ring wings by a soil body, thereby remarkably improving the resistance of the soil body; and the interaction area of the structure and the soil body is increased by the friction wing, and the bearing capacity of the single pile-friction wing composite foundation is improved.
