The invention discloses a method for pile turning of a large-diameter single pile through a full-rotation crane ship. The method comprises the following steps that S1, ship positioning is conducted, specifically, the crane ship and a transport ship travel to a wind field machine position to be anchored and positioned, and the positions are kept relatively stable; S2, an appropriate sling, an appropriate main lifting rope and an appropriate auxiliary lifting rope are selected, a bearing beam and a limiting stopper are welded on the transport ship in advance, and the single pile can be fixedly placed conveniently; S3, the sling is parallelly hung on a main hook through the main lifting rope, an auxiliary rope is hung on an auxiliary hook, one end of the auxiliary lifting rope is hung on the main hook, the main lifting rope is connected with lifting lugs on the two sides of the single pile, and a tail slipping hook fixed to the other end of the single pile is arranged at the other end of the auxiliary lifting rope; and S4, the single pile is hoisted by the main hook, after the single pile leaves the transport ship, the transport ship is driven away from the crane ship, after the single pile is hoisted until the tail slipping hook is unhooked, the single pile continues to be hoisted to be vertical, and pile turning is completed. The main lifting rope and the auxiliary lifting rope on the crane ship enable the single pile to be more stable under the cooperation of a lifting pile, operation safety is improved, the whole construction process is simple and reliable, and construction efficiency is high.
本发明公开一种全回转起重船翻桩大直径单桩的方法,包括以下步骤:S1:船舶定位,起重船和运输船行驶到风场机位处抛锚定位,保持位置相对稳定;S2:选定好合适的吊索具、主吊绳和副吊绳,在运输船上提前焊接垫梁和限位器,便于单桩的固定置放;S3:主吊绳将吊索具平行挂设在主钩上,副钩上挂设辅助绳将副吊绳一端挂设到主钩上,主吊绳连接单桩两侧的吊耳,副吊绳另一端设置溜尾钩固定在单桩另一端;S4:主钩将单桩吊起,待单桩离开运输船后,运输船驶离起重船,单桩吊升至溜尾钩脱钩后将单桩继续吊升至竖直,完成翻桩。起重船上主副吊绳在吊桩配合下使得单桩可以更加稳固,提高作业安全性,整个施工过程简单可靠,施工效率高。
