摘要 某烟囱设计高150m,为套筒式,外筒采用钢筋混凝土结构,内筒采用钛-钢复合板。钢内筒安装高度为150m,高出外筒3m,直径3.2m。钢内筒安装采用液压提升倒装法,经采取一系列的针对性措施满足吊装要求。钢内筒及附壁环梁整体最大应力为18.1 MPa,满足规范要求。 Combined The design height of a tube-in-tube chimney is 150m.The outer tube is of reinforced concrete structure and the inner tube is made of titanium clad steel plate.Diameter of the steel inner tube is 3.2m and its installation height is 150m,which is 3m higher than the outer tube.Upside-down hydraulic lifting installation method was used for installation of inner tube and a series of specific measures were adopted to satisfy the lifting requirements.The integral maximum stress of steel inner tube and wall-attached ring beam is 18.1 MPa,satisfying the requirements of specification.
