Planning and development of formwork and safety solutions for the construction of complex bridge foundations, abutments and piers
Geometrically demanding pier construction while keeping construction time as well as traffic disruptions on the road and on the canal to a minimum
The intricate geometry of the pylons demanded tailored
solutions. A climbing formwork solution based on the CS 240 climbing
scaffold was designed to provide an economical and safe way to build the 13
'standard pylons', which are between 21 and 41 m high. The climbing
scaffold with retractable formwork was combined with formwork and timber beam
systems up to a formwork height of 5.40 m and a wall inclination up to
30°. CS 240 with formwork sets consisting of H 20 timber beams and
combined with specially designed formwork elements were used at the site on the
Kiel Channel. Due to the complex and varied geometry of the pylons, simply
moving the formwork to the next position in a single cycle wasn't feasible.
This is why the formwork sets were changed in every climbing section.
To build the pylon shafts, Hünnebeck's construction team used SCF 60 self-climbing formwork. As soon as the pylon shaft was completed, the two segments were cantilevered on both sides of the structure. Next, the superstructure was shifted onto the canal pylons, applying the incremental launching method. Once the superstructure was lowered to its final position, the resulting gaps were closed.
