CONSTRUCTION OF THE SCHMIDTSTEDTER PRESTRESSED CONCRETE RAILWAY BRIDGE BY TRANSVERSE MOVEMENT

This paper deals with the planning and construction of the Schmidtstedter bridge in Erfurt. This bridge, an underbridge with two openings of each 16M clear width and 4.75M clear height was to be erected with the least possible interference in the rail and shunting traffic of Erfurt central station. The supporting structure of the bridge, consisting of abutments, centre piers, superstructure, sealing, protective concrete layer and gravel bed, was constructed on a prefabrication site and then moved to the area of operation. The structure body with dimensions of 41.00 x 66.70 x 4.66 M weighed 14000t. Jacking was carried out on ptfe runners via a runway, with four synchronized hydraulic jacks. Foundations were brought in underneath the railroad bed by a mining system. Details are presented relating to the construction of the bridge, the site conditions, foundation installation, movement path, slides, structural body, jacking equipment and method, and the construction stages. /TRRL/
