The invention discloses a novel offshore wind power foundation structure and a construction method thereof. A supporting structure is composed of a sleeve and a wing plate, the supporting structure isinstalled on a steel pipe pile through a sliding device, and the supporting structure and the steel pipe pile are in sliding connection or fixed connection. The construction method of the novel offshore wind power foundation structure comprises the following steps that S1, pile sinking equipment is used for piling; S2, the supporting structure is hoisted and penetrates through the steel pipe pilethrough a sliding device to extend into a seabed foundation; S3, the supporting structure is driven to the designed depth through an auxiliary sleeve; and S4, the auxiliary sleeve is recycled, and subsequent procedures are conducted according to engineering requirements. Additional horizontal resistance provided by the supporting structure is used for improving the horizontal bearing capacity ofthe foundation structure, the size of the wing plate is reduced through the sleeve, the manufacturing, transporting and installing difficulty of the foundation structure is reduced through the supporting structure and the steel pipe pile which are independent of each other, and the foundation structure is suitable for shallow covering layer sea areas and the ocean environment with the water depthbeing 35-50 m.
本发明公开了一种海上风电新型基础结构及其施工方法，支撑结构由套管和翼板构成，所述支撑结构通过滑动装置安装于钢管桩，两者连接方式为滑动连接或固定连接。本发明海上风电新型基础结构的施工方法包括如下步骤：S1利用沉桩设备打桩；S2将支撑结构吊起，通过滑动装置穿过钢管桩，伸入海床地基；S3利用辅助套管将支撑结构打至设计深度；S4回收辅助套管，根据工程需求，进行后续工序。本发明利用支撑结构提供的额外水平抗力，提高基础结构的水平承载能力，利用套管降低翼板尺寸，通过相互独立的支撑结构和钢管桩，降低基础结构制作、运输和安装的难度，使之适用于浅覆盖层海域和水深35~50m海洋环境。
