Design and Build of Paks Danube Bridge, Hungary
The role of general and lead designer of the recently inaugurated Paks-Kalocsa Danube Bridge in Hungary was undertaken by CÉH Zrt. The total length of the bridge is 946 m, of which the length of the extradosed river bridge is 440 m. Span arrangement of the extradosed river bridge is 119+200+119 m and the deck width is 20.86 m. The parabolically haunched stiffening girder is a composite dual cell box section comprised of corrugated steel webs and post tensioned in-situ rc. concrete bottom and top slabs. The extradosed river bridge superstructure was erected by the balanced cantilever method. In the presentation, superstructure camber control is presented on the below structural members: - bespoke designed cable anchorage steel link members at rc. pylon heads - general stiffening girder sections - stiffening girder section with cast-in extradosed cable anchorage members Regarding the pylon structure, the camber control of pylon formwork will be presented for each casting phase, the installation and adjustment of bespoke designed link members, as well as the spatial angle settings of cable anchorage plates. The comparison of proprietary saddle elements with the bespoke designed link member will be presented as well. In the presentation the vertical and horizontal camber setting routine will be explored for the general stiffening girder section. For the deck section with extradosed anchorage members, the site measurement and setting routine of the centreline of cable anchorage tubes along with optional adjustment of anchorage support plates will be presented. The presentation will explore the correction adjustment of the steel protective tubes that are cast-in the top deck plate with a shim plate rings to ensure the installation of the extradosed cables in later construction phases. In the presentation we discuss the designer’s data provision, geodetic measurement, site adjustment sequence and we provide the statement of quantities for the measurement points.
