Pedestrian and cycle path bridge Petershausen train station

A forming PERI shoring solution enables the efficient fabrication of two reinforced concrete ramps parallel to the railway tracks, both 100 m long.
The pedestrian and cycle path bridge winds across the tracks of the Petershausen train station in Constance in the shape of a “Z“. The shell construction took only a few months.
The standing assembly of the PERI UP Flex MDS shoring towers, which are up to 6 m high and connected, is done safely with a guardrail in advance.
The continuously climbing MDS decking ensures safe and thus accelerated assembly sequences for all scaffolding and formwork operations.
The transfer of the high loads is done within the free-standing PERI UP Flex MDS shoring system – without any additional, lateral, inclined struts.
PERI HD 200 main beam areas transfer the bundled line loads of the prefabricated bridging parts along the right and left sides of the tracks into the ground.

Project data

Location: Constance, Germany

  • Z-shaped, barrier-free railway overpass for pedestrians and cyclists
  • The actual bridge is made accessible via two reinforced concrete ramps, led in parallel across the railway tracks, each more than 100 m long, with individual spans of up to 20 m
  • Both ramps have a width of 6 m and an inclination of 6%
  • The layout of both ramps with an offset of more than 30 m reduces the overall length of the structure to 170 m

Requirements

  • Construction work along the railway tracks, and with buildings and traffic routes close by
  • Construction work takes place during ongoing railroad operation
  • Both ramp structures are formed and poured almost simultaneously for time reasons

Customer's benefit

  • Construction of the bridge shell structure within a few weeks
  • Assembly decking of the MDS shoring towers serves as access and working level for scaffold erection and dismantling as well as shuttering and striking
  • Climbing and descending via the decking within the towers ensures safety and accelerates the work process
  • The complete load transfer of the ramp slabs with thicknesses of 50 cm to 55 cm is exclusively done within the free-standing PERI UP Flex MDS shoring system – without any additional, lateral, inclined struts

We use PERI UP MDS for the first time – and we are extremely satisfied with it. All work can be carried out from the decking, protected by the standing tower. Also the complete bracing is done in the system – without any additional struts and push-pull props.

PERI solution

  • Forming, surface-type scaffolding for inclined ramp structure with in-situ construction, based on the PERI UP Flex MDS shoring tower system
  • MDS shoring towers with heights from 1.70 m to 6.00 m with a basic grid of 1.25 m x 1.00 m, connected to the birdcage scaffold in vertical and horizontal direction with ledgers of 1.50 m and 1.00 m
  • PERI HD 200 main beam areas transfer the bundled line loads of the prefabricated track bridging parts along the right and left sides of the tracks into the ground
