The invention discloses a rotary hoisting method for a super-large-diameter shield cutterhead under the working condition that the hoisting height is limited, and aims to solve the problem that when the cutterhead is hoisted into a well by adopting an existing method, an included angle exists between the cutterhead and a designed mounting position, and direct hoisting cannot be carried out. According to the application, the gantry crane and the crawler crane are matched to hoist the cutter head, so that the descending of the cutter head is carried out in a space range with the minimum height limit; the problems that a large occupied area is needed by adopting two crawler cranes in the prior art, and the position distribution of the two crawler cranes on one side of a hoisting well mouth and the axis of the hoisting well is limited by the height space under the special environment of an airport are solved. And safe and reliable rotation of the cutterhead after lifting can be ensured through the rotary lifting appliance, so that the problem that a certain angle difference exists between the cutterhead and a designed mounting position after the cutterhead is lifted in a limited space is solved.

    本申请公开了一种吊高度受限工况下超大直径盾构刀盘旋转吊装方法,旨在解决采用现有方法进行刀盘起吊下井时,刀盘与设计安设位置间存在夹角,无法直接吊装的问题。本申请采用龙门吊及履带吊的配合进行刀盘起吊,使得刀盘的下井在限高最小的空间范围内进行,避免了现有采用两台履带吊需要较大的占位区域及分别占位于吊装井口一侧及吊装井轴线上的位置分布受到机场特殊环境下高度空间限制的问题。且通过旋转吊具可确保刀盘在起吊后的安全可靠转动,由此解决在受限空间下刀盘起吊后与设计安设位置间存在一定角度差异的问题。
