塔桅式烟囱内筒体更换吊装施工技术

Hoisting Technique Used in Changing Inner Barrel of a Blare Stack Supported with Tower Mast

介绍高１２０ｍ塔桅式烟囱内筒体更换的技术难点、施工工艺原理及方法，采用这种方法进行施工，有效地解决了在烟囱断口以上部位设置吊装机具的难题，可使隐患彻底消除，同时避免了在高空拆除和安装保温层的施工作业，保证了工程质量、工期和安全。

This paper describes the technical Challenges in changing the inner barrel of a 120m high flare stack supported with tower mast, and method adopted in the changing operation. By taking this method, the difficulty in setting up hoisting tools above the break - up section of the flare stack was effectively overcome, eliminating completely potential dangers, while avoided the stripping and coating operation of thermal insulation layers high above the ground. The project qualify & term, and safety were well assured.
