Teamwork-oriented complete solution
For ensuring rapid final assembly and problem-free construction site
use, formwork units were delivered already pre-assembled. Here, Peri
formwork assembly teams in German Weissenhorn and Düsseldorf
provideddimensionally-accurate fabricationandpunctual delivery. In
order to achieve the best possible construction results, the technical
processing and static calculations were carried out from the begin-
ning onwards by Belgian and German Peri engineers in exemplary
international teamwork.
Already during the construction of the bridge piers as well as lock
components, the system solutions ensured that work operations
could be performed efficiently and cost-effectively. Thus, one set of
climbing formwork complete with GRV articulated waler formwork
served to form the circular reinforced concrete piers featured in the
ground plan. Due to the system-related closed ring tension, the
2,5mdiameter piers were thus realizedwithout any anchor points.

The new lock bridge crosses the shipping channel at right angles. On both banks of the
river, the bridge construction features two 90° bends – with extremely tight axis radii of
almost 30 m respectively.
INSET:
In the complex area with an extremely tight outer
radius, the concentrated loads of the radially-arranged cantilever brackets are trans-
ferred into the available bridge piers by means of pressure supports.
The Variokit steel composite formwork carriage could be adapted to match the geometrical
and static requirements which included 4,5 m cantilevers. (All Photos: PERI gmbh)
