一种大跨距管道的施工方法与应用

A Construction Method and Application of Large Span Pipeline

对某蒸汽管道跨河工程的设计方案进行了筛选,选定拱管+自然补偿架空敷设方案。对自然补偿量进行了应力验算,可满足设计要求。采用拱管支架,解决了架空管道跨距大的问题,设计跨度满足理论计算结果。

The design scheme of a steam pipeline crossing a river is selected,and the arch pipe+natural compensation overhead laying scheme is selected.The stress calculation of natural compensation can meet the design requirements.The arch pipe support is used to solve the problem of large span of overhead pipeline,and the designed span satisfies the theoretical calculation result.
