The Holland Railways developed the "Betuwe Route" Project whose purpose was to link Rotterdam to the Ruhr Freight Railways in Germany. The Dintelhaven bridge, which has been erected in the "Haven" zone of Rotterdam, was the first structure of this ambitious programme.
The bridge, whose total length is 280 m., has an arch shape and the stay cables hang the steel deck to the arch itself.
The stays are made of hot dip galvanised, 7 wires, 15.7 mm. diameter, high strength (1770 N/mm2), waxed, HDPE coated strands and externally protected by white HDPE sheaths.
Two planes of 15 practically vertical cables, comprising 31 strands each, support the deck with a clear span of 170 metres. A total of 25 tonnes of strand has been used for the stays; the longest cable is 27 metres. Stay cables are protected at the deck end by galvanised steel anti-vandalism tubes.
The extremity anchorages are fixed at the upper end (into the arch) and adjustable at the bottom end, to allow the stays load regulation anytime.
The stay cables have been installed by a Tensacciai team at the erection yard alongside the channel, before the bridge load out and placing to its final position, utilising a winch system for threading the strands.
The strands have been installed by isoelongation at zero tensioning according to the design criteria; the final tensioning stage has been reached thanks to the dead load of the bridge itself; the strands have been prepared with reference to a witness strand of pre-fixed lengths.
