热水管道直埋敷设研究

A Study of Hot-Water Pipeline Directly Buried Installation

以北京首都机场扩建南区主体建筑T3航站楼热网管线为例,对热水管道直埋敷设方式进行了比较,总结出无补偿直埋敷设的设计方法采用应力分类法,计算难度大于有补偿直埋敷设,但无补偿直埋敷设的管道布置形式、施工难度、运行维护及经济性均优于有补偿直埋敷设。

The design methods,pipeline arrangement forms,construction difficulties and operation maintenance between directly buried installation without expansion joint and directly buried installation with expansionjoint are compared.The design results and economy of the two installation methods are also compared with an engineering example.
