The invention relates to a sectional type three-stage two-hoisting pipeline mounting process. The process comprises the following steps of: paying off on the ground, placing a pipeline, and binding a flat hoisting belt for hoisting on the pipeline in advance; arranging and installing each unit of a lifting workbench; using a hoisting load cross arm and the flat hoisting belt to hoist the pipeline till the bottom of the pipeline is higher than the top of a jacking load cross arm of the lifting workbench, installing the jacking load cross arm, making the part, in the flat hoisting belt, of the pipeline fall back to the jacking load cross arm of the lifting workbench, and dismantling the hoisting load cross arm; spreading the pipeline on the jacking load cross arm of the lifting workbench in place and conventionally installing the pipeline, and then installing a pipeline clamp on the jacking load cross arm; mounting a hanging bracket root steel plate; jacking the pipeline to a designed position by using a jacking piston and a bearing cross arm thereof; and performing aligning and leveling in the air, and performing connection; With the sectional type three-stage two-hoisting pipeline installation process and installation equipment adopted, the installation difficulty of the pipeline in air can be reduced, waste caused by invalid installation is reduced, the construction quality is improved, and meanwhile air construction safety accidents are reduced.

    本发明涉及一种分段式三阶段两起吊管道安装工艺,包括以下步骤:在地面放线,摆放管道,管道上预先绑设用于起吊的扁平吊带;布置与安装升降工作台各个单元;利用吊升负载横担和扁平吊带,起吊管道,至管道底部高于升降工作台顶升负载横担顶部,停止,安装顶升负载横担,将扁平吊带中的管道回落在升降工作台顶升负载横担上,将吊升负载横担拆除;将升降工作台顶升负载横担上的管道,摊开就位,进行常规安装,然后在顶升负载横担上,安装管道夹具;安装吊架根部钢板;用顶升活塞及其承载横担顶升到设计位置;空中对正找平,连接即可;本发明能够降低空中管道安装难度,减少无效安装产生的浪费,提高了施工质量,同时减少空中施工安全事故。
