D1 Prešov SO203 bridge
Prešov, Slovakia
To erect the superstructure, construction company Eurovia CS has used two pairs of Doka forming travellers, one of them was already successfully used on the other bridge build by company Eurovia CS – Motorway Bridge SO223 Žilina. Thanks to the modularity of our system, it was easy to adapt the forming travellers for different cross section. Additionally to forming travellers, Doka has also supplied formwork material for hammerheads, which were erected 30m over the ground level. Due to our flexible Load-bearing towers Staxo in combination with tailor made Large-area formwork Top50, Doka has provided safe and cost efficient technical solution, which fulfilled customer expectations.
Challenge:
Variable transverse inclination from -5,0% to 2,5% and casting of hammerhead with 30m high Staxo towers
Solution:
Detailed anchor hole layout concept. Extended anchoring crossbar provided to the site for more flexibility of placement of main suspension anchors. Staxo towers were divided in two 15m high towers using rigid bracing grid.
