The invention provides a single-boom three-hook single pile turning process which comprises the steps that a workboat provided with a crane and a transport ship carrying a horizontally-arranged single pile are moved to a machine position, the workboat and the transport ship are in a linear shape, and a pile top flange of the single pile directly faces the crane; the distance between the transport ship and the workboat is adjusted, two main hooks of a crane are connected with two lifting lugs on the upper portion of the single pile through rigging, an auxiliary hook, close to the single pile, of the crane is connected with the pile bottom of the single pile through a sling and tail slipping pliers, and the bottom of the single pile is wrapped; the crane synchronously and horizontally lifts the single pile through the two main hooks and the auxiliary hook, and the transport ship is removed; and the two main hooks of the crane are lifted synchronously, the auxiliary hooks fall synchronously, pile turning is conducted till the single pile is perpendicular to the horizontal plane, and pile turning is completed. Pile turning of a single pile can be achieved through one workboat, and compared with traditional construction of two workboats, the working efficiency is improved, and the construction risk and cost are reduced.
本发明提供一种单臂架三钩单桩翻桩工艺,包括将设有吊机的施工船、运有水平放置的单桩的运输船移至机位,施工船和运输船呈“一”字型就位,单桩的桩顶法兰正对吊机;调整运输船与施工船之间的间距,将吊机的两个主钩通过索具与单桩的上部两个吊耳连接,将吊机的相对位置靠近单桩的副钩通过吊索、溜尾钳与单桩的桩底连接,为单桩进行兜底;吊机通过两个主钩和一个副钩同步将单桩水平吊起,运输船撤场;吊机的两个主钩同步提升,副钩同步下落,进行翻桩,直至单桩垂直于水平面,完成翻桩。本发明采用一个施工船即可实现单桩的翻桩,相比于传统的两个施工船的施工,增加了工作效率,降低了施工风险和成本。
