火力发电厂套筒烟囱钢内筒施工方案比选

烟囱钢内筒施工同混凝土外筒施工项目一样,均属于技术上高难度、质量上高标准、安全上高风险的"三高工程",而如何将钢筒体安全有序、保质保量地将其组合安装到位,则是烟囱内筒工程施工技术的关键和难点所在,本文重点围绕钢内筒的施工方案选择,分析其安装方案的优劣,并结合工程施工实际,阐明方案的优选。

Selection and Comparison of Tube-in-tube Chimney Schemes

The construction of tube-in-tube chimney is the same as the outer tube with concrete construction projects,both are technically difficult and with high standards of quality,security,high-risk—— "three high-Project",and how to install steel cylinder safely and orderly with good quantity is the key and difficult problem of the tube chimney construction technology ,this paper focuses around the steel tube construction scheme selection, analyzes the pros and cons of their installation and combined with construction engineering practice,the optimal scheme selection is described.
