Aiming at the problems of large beam mass,large span and poor sea conditions encountered in the installation and construction of T type girder for approach bridge of the wharf project of the second phase of Suizhong power plant,the methods of ship and machine positioning,temporary strengthening and accurate positioning in the process of T beam transportation and installation are proposed.T-beam is lifted by special hoisting frame to ensure that both ends of T-beam are under vertical force.Various protective measures are taken during installation.In the process of transportation and installation,temporary reinforcement and accurate positioning are adopted.T-beam installation process is relatively smooth,the feasibility of construction technology has been verified.
