The invention discloses a large-diameter long-distance pipeline hoisting construction process, which relates to the field of pipeline construction, and comprises the following ten operation steps: hoisting a pipeline into a groove, butting the pipeline, mounting a sealing rubber ring, mounting the pipeline, performing a joint hydrostatic test, pulling out the pipeline, finishing the pipeline, treating a joint, constructing an anchor block and backfilling the groove. And hoisting, lowering, connecting and landfill operations of the pipeline are completed. By means of the hoisting mode, namely two-point pocket body hoisting and reasonable groove construction, the safety of hoisting operation is guaranteed, sealing connection of pipelines is achieved, the use stability and leakproofness are effectively guaranteed through the verification of a pressing test, and the percent of pass of engineering is increased.
本发明公开了一种大直径长距离管道吊装施工工艺,涉及管道施工领域,包括管道吊装入槽、管道对接、安装密封橡胶圈、管道安装、接头水压试验、管道的拔出、管道修整、接口处理、镇墩施工和沟槽回填的总计十个操作步骤,完成管道的起吊、下放、连接及填埋作业。本发明通过吊装方式即两点兜身吊装和沟槽的合理施工,保证吊装作业的安全性,实现了管道的密封连接,通过了打压试验验证,有效保证了使用的稳定性和严密性,提高工程的合格率。
