Harpe Bru Bridge, Norway

Projektinformation

Plats: Sør-Fron (Oppland), Norge

  • Total length of extradosed bridge: 320 m
  • Largest span between the pylons: 100 m

Krav

  • Complex cross-sections with 130 cm high cross-ribs on both sides of the upper slab, at each segment
  • Pouring of each segment in two steps: first bottom slab, walls and all ribs, second upper slab
  • Suspending cables at most of the segments; collision with the carriages had to be avoided
  • Assembly had to be orgnized in a special way because of the flood forecast for the river
  • Special planking on the surface of the formwork

Kundfördelar

  • Time savings through simple, fast adaptation to match the changing bridge cross-sections
  • Reduction of workload thanks to fast striking and moving procedure through the hydraulic solution
  • Cost-effective solution due to the rentability of the system components
  • Dimensionally accurate execution
  • PERI complete solution from one source
Mariusz Urbanski
Construction Manager

The chosen solution of using VBC Balanced Cantilevered Carriages proved itself to be correct. Thanks to the high flexibility of the system, we could optimize our project so that the workload necessary to pour each segment was as short as possible. It also had a measurable influence on the assumed schedule.

PERI lösning

  • 4 Balanced Cantilever Equipment units for 5.55 m long segments
  • Customized formwork for varying bridge cross-sections
  • Integration of hydraulic components for fast striking and moving the equipment
  • Safe access and working areas with PERI UP
