Lanaye Lock Bridge, Belgium

Lanaye Lock Bridge, Belgium - In the complex area with an extremely tight outer radius, the concentrated loads of the radially-arranged cantilever brackets are transferred into the available bridge piers by means of pressure supports.
Lanaye Lock Bridge, Belgium - The expansion of the Lanaye lock facility required the new construction of a 200 m long road bridge.
Lanaye Lock Bridge, Belgium - The VARIOKIT steel composite formwork carriage could be adapted to match the geometrical and static requirements which included 4.50 m cantilevers.
Lanaye Lock Bridge, Belgiumj - Construction of the steel composite bridge was carried out using formwork carriages and cantilever brackets – both based on the VARIOKIT modular construction kit.
Lanaye Lock Bridge, Belgium - On both banks of the river, the bridge construction features two 90° bends - with extremely tight axis radii of almost 30 m respectively.

Customer

BESIX, Brussels

Customer's benefit

  • Cost-effective project solution through the use of rentable system components in combination with project-specific adjustments
  • Maintaining a tight construction schedule
  • Rapid final assembly and therefore fast on-site availability thanks to pre-assembled formwork elements

Due to our positive experience with similar projects, we decided once again in favour of PERI. Their technical support within the framework of the tight schedule as well as the project solution using the formwork carriage and cantilever brackets have confirmed our decision.

PERI solution

  • two VARIOKIT steel composite formwork carriages for the main bridge with 13 casting segments using the back-step construction method
  • VARIOKIT cantilever bracket units in the tight bend areas
  • Project-specific special solution pressure supports on the circular piers for cantilevering on the external side
