The invention discloses an on-line stress monitoring multi-point synchronous pipeline lifting method, which relates to the technical field of pipeline repair, and comprises the following steps: S1, pipeline displacement calculation: analyzing and calculating the settlement displacement of a liquid inlet pipeline by combining a design drawing and field measurement; s2, a temporary limiting support is installed, specifically, the temporary limiting support is installed on the tank front steel structure frame layer; s3, a pipeline lifting bracket is installed, and a steel structure bearing frame is installed on the tank front steel structure frame layer to serve as a pipeline supporting and hanging frame fulcrum; s4, setting a pipeline lifting measure, S5, setting a pipeline lifting monitoring facility, calculating a stress concentration position through modeling, and setting a monitoring point at a position with relatively large strain; and S6, pipeline lifting confirmation. According to the online stress monitoring multi-point synchronous pipeline lifting method, the problem that on the premise that the strain is controllable, overall displacement is conducted on the system through the same pulling force at multiple points is solved, pipeline droop repairing can be met, cost and materials are saved, efficiency is improved, and the ecological environment is protected.

    本发明公开了一种在线应力监测多点同步管道提升方法,涉及到管道修复技术领域,包括:S1、管道位移计算,结合设计图纸及现场测量对进液管线的沉降位移进行分析计算;S2、安装临时限位支架,在罐前钢结构框架层安装临时限位支架;S3、安装管道提升托架,在罐前钢结构框架层安装钢结构承重框架作为管道支吊架支点;S4、设置管道提升措施,S5、设置管道提升监测设施,通过建模计算应力集中位置,在应变较大位置设置监测点;S6、管道提升确认。提供的在线应力监测多点同步管道提升方法,解决了在应变可控的前提下,多点以相同拉力对系统进行整体移位的问题,能够满足管道下垂的修复,节省了成本和材料,提高了效率,保护了生态环境。
