Self-elevating platform screw pile foundation and operation method thereof
The invention discloses a self-elevating platform screw pile foundation and an operation method thereof. The self-elevating platform screw pile foundation comprises two foundation structures, namely a bare transmission shaft type self-elevating platform screw pile foundation and a truss type self-elevating platform screw pile foundation, and the main function of the two foundation structures is that when the self-elevating platform legs are lowered, the screw pile rotates to generate downward penetration force, and the upper large-diameter screw blade avoids the puncture problem when the screw pile penetrates into a soft soil layer from a hard soil layer; and compared with huge disturbance generated by traditional pile shoe penetration to a soil body, the penetration of the spiral pile cannot dump a large amount of the soil body, the soil squeezing effect is weak, and important significance is also achieved for the safety of a platform close to a fixed jacket.
本发明公开了一种自升式平台螺旋桩基础及其作业方法，包括两种基础结构：一种裸传动轴式自升式平台螺旋桩基础和一种桁架式自升式平台螺旋桩基础，这两种基础结构的主要作用在于自升式平台桩腿下放时，螺旋桩的转动产生向下的贯入力，上部大直径螺旋叶片避免螺旋桩从硬土层贯入至软土层时产生穿刺问题。相比于传统桩靴贯入对土体产生的巨大扰动，螺旋桩的贯入，不会大量排开土体，挤土作用弱，对于临近固定导管架平台的安全，也具有重要意义。
