火力发电厂套筒烟囱钢内筒施工方案比选

Selection and Comparison of Tube-in-tube Chimney Schemes

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。

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.
