Self-elevating wind power installation platform pile shoe and pile inserting and pulling method matched with self-elevating wind power installation platform pile shoe
The invention relates to the technical field of wind power installation platform manufacturing, in particular to a self-elevating wind power installation platform pile shoe and a pile inserting and pulling method matched with the self-elevating wind power installation platform pile shoe. The self-elevating wind power installation platform pile shoe comprises a pile shoe body and an anti-sliding unit. The pile shoe body performs axial displacement motion in the ocean depth direction under the action of dragging force from the pile leg unit. The anti-sliding unit is composed of a power part and N anti-sliding subunits. The anti-sliding subunit comprises a piercing pin. The piercing pin is inserted into the pile shoe body in a matched mode and performs circumferential rotation motion under the action of the power part. And a conical thread section is formed on the piercing pin. Therefore, on one hand, the transverse anti-sliding capacity of the pile shoe can be effectively improved; on the other hand, due to the fact that the piercing pin can continuously execute the circumferential rotation motion, in the pile inserting stage, the piercing pin is easier to go deep into the batholith seabed geological layer under the assistance of the conical thread section; and in the pile pulling stage, the difficulty that the piercing pin is separated from the batholith seabed geological layer can be reduced.
本发明涉及风电安装平台制造技术领域，尤其是一种自升式风电安装平台桩靴及与其相适配的插拔桩方法。自升式风电安装平台桩靴包括桩靴本体和抗滑移单元。桩靴本体在来自于桩腿单元的拖动力作用下而沿着海洋深度方向执行轴向位移运动。抗滑移单元由动力部和N个抗滑移子单元构成。抗滑移子单元包括有刺地销。刺地销插配于桩靴本体内，且受到动力部的作用而执行周向旋转运动。在刺地销上的成型出有锥形螺纹段。如此，一方面，可有效地提升桩靴的横向抗滑移能力；另一方面，因刺地销可持续地执行周向旋转运动，在插桩阶段，且刺地销在锥形螺纹段的助力下更易于深入岩基海床地质层；而在拔桩阶段，可降低刺地销经由岩基海床地质层中脱出的困难度。
