The Application of Pre-installation Technology of Tower Silo Slip Form Strip Steel Truss Girder

On the basis of the real engineering situation,pre-installation technology of tower silo slip form strip steel truss girder is introduced.Due to the big diameter of the silo,large height,large weight of the truss girder,and the small installation site,the installation of the truss girder is difficult.By using elevating system of tower silo slip form to lift the truss girder to the needed height,the installation will be safer and more reliable.Construction period can be shortened and cost can be reduced.
