The invention discloses a method for overturning a large-diameter single pile by a fixed arm frame crane ship. The method comprises the following steps that: 1, the crane ship is positioned; 2, a transportation ship is positioned; 3, a crane ship lifting rope is hung; 4, the single pile is hung; 5, the single pile is lifted; and 6, the single pile is put down, overturned and erected. The construction method uses the fixed arm frame crane ship with double arm frames; and compared with a full-rotation crane ship, the cost is lower, the use cost is lower, and the construction cost is saved. The arm frames are clamped at one end of the single pile through flat mouth hooks; and after a lifting pile is sunk into the seabed, the lifting pile is put down for automatic unhooking, so that the unhooking is simple, the pile overturning difficulty is low, and the pile overturning efficiency is high. A cable rope is additionally arranged in a lifting lug of the single pile for assisting in stabilizing the pile body posture during lifting to protect the pile erecting stability, so that the construction process is more reliable and stable.
本发明公开一种固定臂架起重船翻转大直径单桩方法,包括以下步骤:步骤一:起重船定位;步骤二:运输船就位;步骤三:起重船吊索具挂设;步骤四:单桩挂设;步骤五:单桩起吊;步骤六:单桩下放及翻身立桩;本施工方法使用具有双臂架的固定臂架起重船,相比全回转起重船成本较低,使用成本较低,有利于节约施工成本。臂架通过扁嘴钩卡接在单桩的一端上,吊桩沉入海底之后下放自动脱钩,脱钩简单、翻桩难度低,翻桩的效率高。单桩的吊耳处还另外设有缆风绳辅助在起吊的时候稳定桩体姿态,保护立桩的平稳性,让施工过程更加可靠稳定。
