Motorway bridge over the Drava, Croatia

Motorway bridge over the Drava, Osijek, Croatia - A VARIOKIT cantilevered parapet carriage serves for constructing the external cantilevered parapets.
Motorway bridge over the Drava, Osijek, Croatia - The precast beams of the foreland bridges are supported on 180 cm thick circular columns complete with mushroom shaped heads.
Motorway bridge over the Drava, Osijek, Croatia - The internal cantilevered parapets are formed by a movable solution of a construction of VARIOKIT and PERI Up system components.
Motorway bridge over the Drava, Osijek - efficient construction has been ensured by PERI engineers by combining the CB and RCS climbing systems to create a customized formwork solution.
Motorway bridge over the Drava, Osijek, Croatia - in the lower part, a cross connection for the pylon legs serves as bracing.
Motorway bridge over the Drava, Osijek, Croatia - On the forward and reversed-inclined outer walls, the rail-guided RCS formwork is climbed by means of mobile hydraulic units.

Project data

Location: Osijek, Croatia

  • New construction of a 2,485 m long bridge as part of the A5 motorway development in eastern Croatia, consisting of one suspension bridge and approach bridges in the flood area of the River Drava.
     
  • Two foreland bridges each approx. 1,000 m long, designed as beam bridges each with 35 m span widths
  • construction with pre-fabricated pre-stressed concrete beams
  • supported on circular reinforced concrete piers with 180 cm diameters and mushroom-shaped heads.
     
  • Cable-stay bridge with 3 segments (100 m / 220 m / 100m spans), suspended on two A-shaped pylons with heights of 75 m
  • carriageway realized using a steel composite construction.

Requirements

  • circular columns (180 cm diameters) with mushroom-shaped heads
  • formwork for the field factory for construction of pre-stressed, I-shaped bridge beams
  • reinforced concrete cantilevered parapets for the edge and middle areas of the two separated carriageways
  • climbing formwork for the pylons with a constantly changing cross-section
  • short construction time, fastest-possible adaption of the formwork solution to the existing cross-sections
