The invention relates to a four-pile jacket foundation steel pipe pile tail turning method, which is characterized in that a bottom plate, a saddle, a short longitudinal baffle, a high longitudinal baffle, a spacing sole timber, a turning sole timber and other devices are arranged on a deck of a transport ship, so that layered transportation and storage of steel pipe piles are realized, the transportation efficiency and the space utilization rate are improved, and a hydraulic pile turning device is adopted to clamp the pile top, so that the pile top can be turned. The amplitude of an arm support is adjusted through a large arm of a workboat, stable turning over of a pipe pile is achieved under the condition that a pile bottom fulcrum is not moved, the influence of a traditional lifting lug turning over mode on a jacket is avoided, and meanwhile through the strength design of a short longitudinal gear and a high longitudinal gear and the arrangement of a sliding rod set, a rotating block set and other devices, the pipe pile can be turned over stably. According to the method, the continuity and stability of posture conversion in the pipe pile turning process are achieved, damping adjustment and limiting supporting measures are matched, the adaptability and controllability of the turning device are effectively improved, the construction efficiency and safety of large-size steel pipe piles in ocean engineering such as offshore wind power can be improved, and the method has good application and popularization prospects.
本发明涉及一种四桩导管架基础钢管桩尾部翻身方法,通过在运输船甲板上设置底板、鞍座、矮纵挡、高纵挡、间隔垫木和翻身垫木等装置,实现了钢管桩的分层运输和存放,提高了运输效率和空间利用率,采用液压翻桩器夹持桩顶,利用施工船大臂调节臂架幅度,在桩底支点不动的情况下实现了管桩的平稳翻身,避免了传统吊耳翻身方式对导管架的影响,同时,通过矮纵挡和高纵挡的强度设计以及滑杆组、转动块组等装置的布置,实现了管桩翻身过程中姿态转换的连续性和稳定性,配合阻尼调节和限位支撑措施,有效提高了翻身装置的适应性和可控性,该方法可提升海上风电等海洋工程中大尺寸钢管桩的施工效率和安全性,具有良好的推广应用前景。
