Single pile construction process and self-elevating wind power installation platform
The invention provides a single pile construction process and a self-elevating wind power installation platform. The single pile construction process comprises the following steps of moving the self-elevating fan installation platform to a position near a pile position, and carrying out coarse positioning on the platform by using an anchoring device; displaying the position of the self-elevating fan installation platform through a DGPS, adjusting the length of an anchor cable, accurately positioning the platform, and ensuring that the center of a hydraulic pile gripper is positioned at the center of the pile position; using a lifting device to descend a pile leg, inserting the pile leg into the seabed plane, and meanwhile, jacking the self-elevating fan installation platform; using a crane for hoisting the single pile to the hydraulic pile gripper through a steel wire rope, controlling and adjusting the perpendicularity deviation of the single pile to be not larger than 0.1% through the hydraulic pile gripper, and using a hydraulic pile hammer for conducting pile driving operation on the single pile; and using the hydraulic pile gripper for controlling the perpendicularity deviation of the single pile, enabling the perpendicularity deviation of the single pile to be always kept not to exceed 0.1% in the piling process of the single pile, and ensuring the perpendicularity of the single pile during sinking, so that the construction operation efficiency is improved, and the construction cost is reduced.
本发明提出一种单桩施工工艺及自升式风电安装平台，包括以下步骤：自升式风机安装平台移动至桩位附近，利用锚定装置对平台进行粗定位；通过DGPS显示自升式风机安装平台的位置，调整锚缆长度，对平台进行精确定位，确保液压抱桩器的中心定位于桩位的中心；升降装置将桩腿降下，将桩腿插入海底平面，同时将自升式风机安装平台顶升；吊机利用钢丝绳将单桩吊起搬至液压抱桩器，通过液压抱桩器控制调整单桩的垂直度偏差不超过0.1％，利用液压打桩锤对单桩进行打桩作业；利用液压抱桩器对单桩的垂直度偏差进行控制，在对单桩的打桩过程中始终保持单桩的垂直度偏差不超过0.1％，保证单桩下沉时的垂直度，提高施工作业效率，降低施工成本。
