Offshore wind power jacket foundation lifting-lug-free pile feeder and mounting method
The invention relates to the technical field of pile sinking construction, and discloses a lifting lug-free pile feeder for an offshore wind power jacket foundation and an installation method.A self-locking pile gripper capable of achieving self-locking through friction force is combined with a hydraulic pile driver and matched with an upper pile feeder sleeve and a pile foundation positioning seat fixed to a working platform, so that the lifting lug-free pile feeder for the offshore wind power jacket foundation is formed. The self-locking pile clamping device and the pile feeder sleeve are locked at the moment of hammering of the hydraulic pile driver, so that the hydraulic pile driver and the offshore working platform are temporarily locked, upward jumping of the hydraulic pile driver is strongly restrained, all force acts on a pile foundation, and the pile foundation is prevented from being damaged by the self-locking pile clamping device and the pile feeder sleeve. And the piling efficiency is improved.
本发明涉及沉桩施工技术领域，公开了海上风电导管架基础无吊耳式送桩器及安装方法，通过可以利用摩擦力自锁的自锁夹桩器，和液压打桩机相结合，配合上送桩器套管和固定在工作平台上的桩基定位座，令送桩器套管只能向下无法向上，在液压打桩机锤击的瞬间，使得自锁夹桩器和送桩器套管发生锁死，进而使得液压打桩机和海上工作平台发生短暂的锁死，强力抑制了液压打桩机的上跳，使得所有的力量都作用在桩基上，提升了打桩的效率。
