Offshore wind power combined foundation and construction method thereof
The invention discloses an offshore wind power combined foundation and a construction method thereof and relates to the field of wind power generation. The offshore wind power combined foundation comprises a single-pile foundation and at least three auxiliary screw piles arranged in the circumferential direction of the single-pile foundation at intervals, and the auxiliary screw piles are connected to the single-pile foundation. The auxiliary screw pile comprises an auxiliary screw pile shell, a top plate arranged in the auxiliary screw pile shell, a driving mechanism used for driving the top plate to move in the axial direction of the auxiliary screw pile, and a ball screw with the top abutting against the top plate. The ball screw nut is arranged on the ball screw rod in a sleeving mode through threads, the top of the spiral drilling rod is connected with the bottom of the ball screw rod, and the bottom of the spiral drilling rod extends to the position below the auxiliary spiral pile shell. The offshore wind power combined foundation and the construction method thereof have the advantages of being high in bearing capacity, high in anti-pulling capacity, good in stability and reliability and convenient to construct and maintain, the installation time can be saved, and the operation and maintenance cost can be reduced.
一种海上风电组合基础及其施工方法，涉及风力发电领域。海上风电组合基础包括单桩基础及至少三个沿单桩基础周向间隔布置的辅助螺旋桩，辅助螺旋桩连接于单桩基础，辅助螺旋桩包括辅助螺旋桩外壳、设于辅助螺旋桩外壳内的顶板、用于驱动顶板沿辅助螺旋桩轴向移动的驱动机构、顶部抵压顶板的滚珠丝杠螺杆、通过螺纹套设于滚珠丝杠螺杆上的滚珠丝杠螺母及顶部与滚珠丝杠螺杆底部连接的螺旋钻进杆，螺旋钻进杆的底部伸出至辅助螺旋桩外壳下方。本申请提供的海上风电组合基础及其施工方法具有承载力高、抗拔能力强、稳定性和可靠性好、施工和维护方便的优点，能够节约安装时间并降低作业和维护成本。
