The invention provides a double-arm-frame four-hook pile turning process for a single pile. The method comprises the steps that a workboat and a transport ship enter a machine position, the workboat and the transport ship are placed in a T shape, a single pile flange and a crane form an angle of 90 degrees, after the workboat and the transport ship are placed in place, the distance between the transport ship and the workboat is adjusted, two main hooks on one arm frame of the floating crane ship are connected with two lifting lugs of a single pile through rigging, and the single pile flange and the single pile flange are connected through the rigging. The two main hooks on the other arm frame are connected with the single pile through rigging and shackles, the four hook heads synchronously lift the single pile to a certain height through steel wire ropes and lifting belts, the transport ship is driven away, and the four main hooks synchronously fall down until the pile body of the single pile is in contact with the seabed mud surface, so that the single pile is turned over in the sea; the single double-arm workboat is mainly used for being matched with the transport ship to work a single pile, and therefore the effects that the processes of pile turning, pile holding and pile driving are directly completed, the construction efficiency is greatly improved, and the construction cost is reduced are achieved.
本发明提供一种双臂架四钩单桩翻桩工艺。本发明方法,包括:施工船和运输船入机位,施工船和运输船“丁”字就位,单桩法兰与吊机方向成90°,就位完成后,调整运输船与施工船间距,将浮吊船的其中一个臂架上的两个主钩,分别通过索具与单桩的两个吊耳相连,另一个臂架上的两个主钩则通过索具、卸扣连接单桩,四个钩头通过钢丝绳和吊带将单桩同步起吊抬桩至一定高度,运输船驶离,四主钩同步下落,直至单桩桩身触及海底泥面,使单桩在海中完成翻身,本发明主要利用单个双臂施工船配合运输船对单桩进行作业,从而起到直接完成翻桩、抱桩及打桩的过程,大大提高施工效率,降低施工成本的效果。
