关于热力直埋管道漂移问题的研究

Research and analysis on drifting problems of the directly-buried heating pipe

在供热管网运行中,位于竖井内的拉杆补偿器存在外推变形现象,对管网的运行造成极大的安全隐患,以直埋供热管道理论为依据,通过模型建立、受力分析及工程实例计算进行了研究,提出解决驻点漂移的方法,降低施工难度,减少工程投资,提高管网运行的安全性和稳定性。

In lihgt of rod compensator extrapolatng deformation phenomenon in the vertical shaft during the heating pipeline network operating process,the paper stuides the pipeline network operation hazards through establishing model,stress analysis and engineering example calculation on the basis of directly-buried pipe theory,and puts forward stagnation point drifting solving method,so as to reduce construction difficulty,reduce engineering investment and improve pipeline network operation safety and stability as well.
