摘要
在朔州市神头泉水置换水厂预应力钢筒混凝土管线工程施工中,遇到了一系列影响安装的问题,诸如橡胶密封圈的合理选择性、气温对安装的影响、如何处理椭圆度带给安装的影响、预应力钢筒混凝土、(PCCP)包封混凝土施工中的教训和经验等,文中对之详尽地进行了阐述。
During the construction period to install PCCP of Shentou Spingwater-replacing Plant in Shuozhou City,a series of problems that influences installation job was encountered,including how to reasonably select rubber water-seal ring,the influence of air temperature on installation job,how to treat the problem brought by elipticity of steel circle on pipe joint and the experiences and lessons in the process to place concrete surrounding PCCP etc.All of these are detailed in this paper.
