Krakow-Plaszow railway junction: cost-effective cable-stayed bridge erection

The following images, photographs, illustrations, videos and media or "Krakow-Plaszow railway junction: cost-effective cable-stayed bridge erection" include visual details and information about this product or case study.

Thanks to the detailed planning provided by PERI engineers and high flexibility of the PERI balanced cantilever equipment, the superstructure of the cable stay bridge could be completed according to the schedule.

When moving the PERI cantilevered construction carriage above the overhead lines, the safety of construction team and the adjacent area was always guaranteed through the compatibility with the PERI UP modular scaffolding.

Construction of the 252 m long crossing over the Krakow-Plaszow railway junction was carried out using four VARIOKIT cantilevered construction carriages

Heavy railway traffic at one of the busiest stations in Poland remained undisturbed during construction thanks to the PERI balanced cantilever equipment.

In the foreland area, PERI UP Rosett Flex load-bearing system together with a throughway consisting of HD 200 heavy-duty props was used as shoring solution to support the 207 m long viaduct. Thanks to 25 or 50 cm system grid, the position of the legs could be flexibly adapted to accommodate the respective loads. The aluminium PERI UP Rosett staircases served as safe access means for site personnel

As part of the Krakow metropolitan railway system expansion, a 40 m high asymmetrical viaduct pylon was erected in the second phase of construction, featuring a combined A and H geometry. At two thirds of the pylon height, horizontally suspended SB brace frames were used. These formed a load-bearing intermediate platform for the crossbeam, a technological platform for the reinforcement materials as well as, in the final phase, a sub-construction for the scaffolding in order to install the stay cables. The PERI comprehensive solution allowed short concreting cycles with the highest possible safety standards
