According to the deepwater sea area offshore wind power project jacket foundation olecranon hook pile turning method, a pile turning channel is arranged on a transport ship, and tools such as olecranon hooks, pile turning devices, chain stoppers, winches and pile clamping devices are arranged on the channel, so that underwater pile turning operation of steel pipe piles is achieved. The hydraulic pile clamping device at the pile head replaces a lifting lug, and the construction step of cutting off the lifting lug after pile sinking is completed is eliminated; the arrangement of the pile tail olecranon hook and the pile turning device can realize underwater pile turning of the steel pipe pile, and the limitation of the length of the transport ship is reduced to the maximum extent. Meanwhile, operation is easy, safety and practicability are achieved, and assembly line production can be formed through site construction. The requirement for ship machine equipment is low, and cost is saved; the safety risk is low, and overall installation is convenient. Pile turning construction is systematized, repeated use can be achieved, and the work efficiency is high; pile turning is assisted by the hydraulic pile clamping device, so that the time for cutting off the lifting lug underwater is saved, and the safety risk is reduced; the structure is simple, manufacturing materials are saved, cost is saved, and high economic benefits are achieved.
一种深水海域海上风电工程导管架基础鹰嘴钩翻桩方法,通过在运输船上设置翻桩通道,通道上布置鹰嘴钩、翻桩器、止链器、卷扬机、夹桩器等工机具,实现钢管桩水下翻桩作业。桩首的液压夹桩器取缔了吊耳,消除了沉桩结束后割除吊耳的施工步骤;桩尾鹰嘴钩、翻桩器的设置可以实现钢管桩在水下翻桩,极大限度地降低了运输船船长的限制。同时本专利操作简单,安全实用,现场施工可形成流水线生产。对船机设备要求低,节省成本;安全风险低,整体安装便利。将翻桩施工系统化,可重复使用,工效高;依靠液压夹桩器辅助翻桩,省去了在水下割除吊耳的时间,降低安全风险;其结构简单,节省制作材料,节约成本,具有较高的经济效益。
