吉林长山热电厂第五期扩建工程中的180m烟囱,由我局采用液压滑模工艺施工。滑模施工仅完成主体——筒身结构,按设计要求筒身内还有13层挑出的牛腿,用来支撑砖内衬。牛腿需要在滑模施工后,重新将混凝土刨毛,焊接钢筋,支模浇筑混凝土。180m烟囱壁厚是渐变的,最厚是底部44cm,最薄处18cm。13层牛腿距离15.0～ The 180m chimney in the expansion project of the fifth phase of Jilin Changshan Thermal Power Plant was constructed by our bureau using a hydraulic sliding mode process. Slipform construction only completes the main body - the structure of the barrel. According to the design requirements, there are 13 layers of bull legs that are used to support the brick lining. After the construction of the slipform, the calf needs to reconstruct the concrete, weld the reinforcement, and cast the concrete. The wall thickness of the 180m chimney is gradual, with the thickness being 44cm at the bottom and 18cm at the thinnest. 13 layers of cow legs distance 15.0 ~
