Based on the pushing and installing of 78 m steel truss girders during the construction of the flyover over railway lines on the Northern Ring of East Section of Beijing-Tianjin Expressway under Contract No.5,the paper focuses on the tech-nical preparations for the installation of steel truss girders,such as erection of a platform for assembling of steel truss girders,construction of temporary piers,fabrication and erection of the slipway and nose-girder,determination of the pushing gear and its location,and process control of pushing and installing.The technology proved successful and the construction practice shows that,without interference with the normal operation of existing railway lines,it is faster,safer and reliable to install the steel trusses by pushing.
