Large-caliber long distance pipeline large-span integral hoisting construction method

The invention discloses a large-caliber long distance pipeline large-span integral hoisting construction method. The construction method comprises the following steps that r ditch entering machines and tools are prepared, a ditch entering operation scheme of a pipeline is formulated according to pipeline properties, pipe ditch depth, pipe ditch inner pipeline suspended length and hoisting data, and pipeline hoisting is carried out according to the ditch entering operation scheme, and the pipe ditch is backfilled in time after the ditch entering of the construction section pipeline is completed. Mechanized construction is adopted, standardized laying of a large-caliber long distance pipeline is achieved, and popularization and use are facilitated. 本发明公开了大口径长输管道大跨度整体吊装施工方法，包括：准备好下沟机具，根据管道性质、管沟深度、管沟内管道悬空长度和吊装数据制定管道的下沟作业方案；根据下沟作业方案进行管道的吊装，本施工段管道下沟完成后及时回填管沟。本发明采用机械化施工，实现了大口径长输管道的标准化铺设，有利于推广使用。
