The invention provides a pile leg pitching folding method. The pile leg pitching folding method comprises the following steps that pile leg segmentation and pile shoe construction are carried out; a pile leg section and a pile shoe are built respectively, and the tolerance directions of the pile leg section and the pile shoe are the same and are controlled within a preset tolerance range; assigning a reference cross curve of a pile leg insertion position on the pile shoe; the trunk sections are closed, and the horizontal projection of the trunk deck datum line and the horizontal projection of the datum cross curve on the pile shoe coincide; the lower pile fixing frame is closed, and the rack datum line of the lower pile fixing frame coincides with the horizontal projection of the trunk deck datum line and the horizontal projection of the datum cross curve; closing the upper pile fixing frame; adjusting the tooth tip of the gear box to face downwards; hoisting the pile leg sections and closing the inserted piles; overturning the pile leg sections to enable the pile leg sections to extend in the vertical direction; a pile leg section is lowered, and a rack plate is inserted between left and right gearbox gears of an upper pile fixing frame; driving the pile leg subsections to move downwards through the gear of the gear box until the bottoms of the pile leg subsections move downwards to preset mounting positions in the pile shoe; and the pile leg sections and the pile shoe are welded.

    本发明提供了一种桩腿插桩合拢方法,包括以下步骤:桩腿分段以及桩靴的建造;分别建造桩腿分段以及桩靴,使两者的公差方向为同一方向,并均控制在预设公差范围内;在桩靴上勘划桩腿插入位置的基准十字线;合拢围井分段,使围井甲板基准线与桩靴上的基准十字线的水平投影重合;合拢下固桩架,使下固桩架的齿条基准线与围井甲板基准线和基准十字线的水平投影重合;合拢上固桩架;调整所齿轮箱的齿尖,使其朝向下方;桩腿分段的吊装及插桩合拢;翻转桩腿分段使其沿竖向延伸;下放桩腿分段,使齿条板插入至上固桩架的左右齿轮箱齿轮之间;通过齿轮箱齿轮的驱动使桩腿分段下移,直至桩腿分段的底部下移至桩靴内的预设安装位置;焊接桩腿分段和桩靴。
