The invention relates to the technical field of offshore engineering facilities, in particular to an offshore wind power suction tube jacket mounting method and device.Lifting points are arranged at the two opposite ends of a horizontal jacket body respectively, and the jacket body is overturned to be in a vertical state by controlling the lifting speed of each lifting point; the suction barrel main body and the jacket main body can be directly and vertically conveyed after being installed, the problem that the traditional three-pile suction barrel jacket construction process and equipment investment is large is solved, and the initial investment of the whole device is about 25,000,000 and is far lower than the initial investment of nearly 200 million of ultra-large portal hoisting equipment; a cable rope does not need to be tensioned, so that the influence on a site is minimized; foundation treatment is simple, overall stability is good, and economic benefits are high; the requirements of horizontal construction and integral turnover hoisting splicing of the upper jacket are met, horizontal construction of the upper jacket can be realized, the construction precision and the construction efficiency are improved, and the risk of high-altitude operation is reduced.
本发明涉及海上工程设施技术领域,尤其涉及一种海上风电吸力筒导管架安装方法及装置,在卧倒的导管架主体的相对两端分别设置吊点,通过控制每个吊点的吊装速度,将导管架主体翻转成立式状态,从而便于吸力筒主体与导管架主体的安装,二者安装后可直接立式输送,解决了传统三桩吸力筒导管架建造工艺及设备投资大难题,整个装置初投资约2500万,远远低于超大型门式起重设备的近2亿的初投资;且无需张拉缆风绳,对场地影响最小化;基础处理简单,整体稳定性好,经济效益高;满足上部导管架卧式建造和整体翻身吊装拼接的要求,可实现上部导管架卧式建造,提高了建造精度和建造功效,降低了高空作业的风险。
