Rapid pile sinking construction process for offshore wind power deepwater first pile method four-pile jacket foundation
The invention belongs to the technical field of offshore pile sinking, and discloses an offshore wind power deepwater first pile method four-pile jacket foundation pile sinking rapid construction technology which comprises the steps that a floating crane ship is moved to a first position; a hoisting suspension arm of the floating crane lifts the suction bucket positioning frame to a mounting position in water, and the suction bucket positioning frame penetrates into mud after being leveled; the transport ship bearing the steel pipe piles is berthed at the second position; the hoisting suspension arm hoists and turns over the steel pipe pile at the deck of the transport ship through the inner lifting lug of the steel pipe pile; after the hoisting suspension arm hoists the steel pipe pile to the position above the suction bucket positioning frame, the steel pipe pile is inserted into a sleeve of the suction bucket positioning frame; hoisting the hydraulic hammer by the hoisting suspension arm to perform first-wheel piling on the steel pipe pile in the sleeve; the hoisting suspension arm simultaneously hoists the pile feeder and the hydraulic hammer, and secondary-wheel piling is conducted on the steel pipe pile obtained after primary-wheel piling is conducted; and the hoisting suspension arm hoists the in-mud suction bucket positioning frame above the mud surface. The low-cost and high-efficiency pile sinking operation is completed through the floating crane ship, the positioning frame, the deck pile turning, the inner lifting lug, the pile feeder, the hydraulic hammer and the like.
本发明属于海上沉桩技术领域，公开了海上风电深水先桩法四桩导管架基础沉桩快速施工工艺，包括浮吊船移动至第一位置处；浮吊船的起重吊臂吊运吸力桶定位架于水中安装位置处，吸力桶定位架调平后沉贯于泥中；承载有钢管桩的运输船停泊于第二位置处；起重吊臂通过钢管桩的内吊耳于运输船甲板处起吊翻转钢管桩；起重吊臂吊运钢管桩至吸力桶定位架上方后，将钢管桩插装于吸力桶定位架的套筒中；起重吊臂起吊液压锤对套筒内钢管桩进行首轮打桩；起重吊臂同时起吊送桩器和液压锤，对首轮打桩后的钢管桩进行次轮打桩；起重吊臂吊运泥中吸力桶定位架于泥面上方。本发明通过浮吊船、定位架、甲板翻桩、内吊耳、送桩器和液压锤等完成低成本高效的沉桩作业。
