Offshore wind power combined type single pile foundation and construction method thereof
The invention relates to an offshore wind power combined type single pile foundation and a construction method thereof. The combined type single pile foundation comprises a steel pipe pile and a plurality of variable-section T-shaped wing plates; mortise grooves matched with the variable-section T-shaped wing plates in quantity are formed in the outer surface of the steel pipe pile in the verticaldirection, and tenons matched with the mortise grooves are arranged on the variable-section T-shaped wing plates so that the variable-section T-shaped wing plates and the steel pipe pile are fixedlyconnected through mortise and tenon joint structures composed of the mortise grooves and the tenons. Compared with the prior art, according to the single pile foundation and the method, the problem ofvertical deviation rectification of single pile foundations can be solved to a certain extent, the applicability of the single pile foundation in a deepwater sea area is improved, and the single pilefoundation and the method have the advantages of high overturning resistance, high bearing capacity, convenient construction, and good economic benefit.
本发明涉及一种海上风电组合式单桩基础及其施工方法，该组合式单桩基础包括钢管桩、以及若干变截面T型翼板，所述的钢管桩的外表面沿竖向设有数量匹配所述变截面T型翼板的卯槽，所述的变截面T型翼板上设有与所述卯槽匹配的榫头，使得变截面T型翼板与钢管桩之间通过由卯槽与榫头组成的榫卯结构固定连接。与现有技术相比，本发明可一定程度上解决单桩基础垂直纠偏问题，提高单桩基础在深水海域的适用性，且具有抗倾覆能力高、承载力高、施工方便、经济效益好等优点。
