Title:
NOVEL OFFSHORE WIND TURBINE FOUNDATION SUITABLE FOR SHALLOW COVERING LAYER AND CONSTRUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/127466
Kind Code:
A1
Abstract:
A novel offshore wind turbine foundation suitable for a shallow covering layer and a construction method therefor, the offshore wind turbine foundation comprising a single pile (1). A gravity disc (3) is fixedly mounted on the single pile (1); a plurality of helical piles (2) are evenly distributed on the periphery of the gravity disc (3); and adjacent helical piles (2) are fixedly connected to each other to form an integral structure. The uplift-resisting bearing capacity and horizontal bearing capacity of the foundation are improved by means of the helical piles (2) and the gravity disc (3); the horizontal displacement of the pile body is reduced; the bending moment of the pile body is reduced; and the combination and rigid connection of the helical piles (2), the gravity disc (3), and the single pile (1) improve various mechanical properties of the whole foundation, such that the construction requirement for safe and stable operation of an offshore wind turbine can be met without needing to inserting the single pile (1) into the bedrock.
