Filstal Bridge, Mühlhausen im Täle, Germany

The 85 m high and 485 m long Filstal Bridge brings together all the challenges of bridge construction: a sophisticated construction method with slender superstructures and high bridge piers that widen in a Y-shape at the crown, high architectural concrete requirements and a narrow time window to meet the completion deadline.
The cantilevered parapets on the west bridge were constructed in 24-m-sections using a total of four VARIOKIT Cantilevered Parapet Carriages.
PERI engineers assisted with the construction of the piers, superstructure and tunnel portals using their solution expertise and modular, coordinated formwork and scaffolding systems.
The PERI Tunnel Formwork Carriage had its basis in the VARIOKIT Engineering Construction Kit with rentable system components. In this way, a customised project solution could be developed in the shortest possible time.
The working platforms were kept available along the entire length of the bridge so that the parapet could be constructed in sections on the eastern superstructure. The project-specific VARIOKIT solution from the PERI engineers took the additional assembly and finishing platform applications into consideration.
The slender reinforced concrete shafts sprouted upwards, cycle by cycle, with the aid of the rail-guided RCS climbing formwork.
In the complicated expansion areas at the pier head, working platforms based on the RCS and SCS climbing systems ensured that the loads could be transferred safely. For this, PERI UP reinforcement scaffolds installed around the perimeter provided a safe working environment.
PERI engineers designed a rail-guided finishing carriage by combining the PERI UP Scaffolding System with VARIOKIT and RCS climbing technology in order to work on the inclined piers.
The compatibility of the VARIOKIT and PERI UP modular systems meant that customised project solutions could be achieved for the cantilevered parapet construction process and for finishing the superstructure and the inclined piers above the Y-pier head.
With safe, coordinated work processes, deadlines could be met without any interruptions that might delay construction. The high level of working safety facilitated both the formwork and scaffold assembly processes as well as subsequent use at great heights.

プロジェクト情報

ロケーション: Mühlhausen im Täle, ドイツ

  • The 485 m long Filstal Bridge is part of the new high-speed Wendlingen-Ulm railway line.
  • At a height of 85 m, it is one of the highest railway bridges in Germany, connecting the Boßler Tunnel in the north with the Steinbühl Tunnel in the south.

現場でのニーズ

  • As the tracks run on two separate bridge sections, the structure is extremely demanding in terms of architecture and engineering.
  • The Filstal Bridge brings together all the challenges of bridge construction: high bridge piers that widen in a Y-shape at the crown, a sophisticated construction method with slender superstructures, high architectural concrete requirements and a narrow time window to meet the completion deadline because of interim adjustments to the structural model of the bridge structure.

お客様にとっての価値

  • Particularly when requirements changed during the construction process, the infrastructure specialists from PERI always found a solution to meet the completion deadline and at the same time achieve a high quality of execution.
  • The metric basic grid of both modular systems, VARIOKIT and PERI UP, paved the way for an almost limitless number of combinations in all respects, which was hugely beneficial for planning, structural analysis and on-site construction work.

When we needed the guys from PERI, there they were. We were always able to find a solution for everything together. Planning and delivery always took place on time.

提案内容

  • PERI engineers assisted with the construction of the Filstal Bridge using their extensive expertise in comprehensive solutions, customer-oriented planning and service capabilities as well as coordinated modular construction systems.
  • In PERI, an equally experienced solution provider for formwork and scaffolding projects was on hand to support the construction consortium partners, Max Bögl and PORR.
  • Particularly when requirements changed during the construction process, the infrastructure specialists from PERI always found a solution to meet the completion deadline and at the same time achieve a high quality of execution.
  • In all phases, digital 3D planning provided visualisations of the formwork and scaffolding use, thus simplifying communication with the various decision-makers.
  • Three PERI modular systems served as the formwork and scaffolding basis for the construction work of the bridge piers: The slender reinforced concrete shafts sprouted upwards, cycle by cycle, with the aid of the rail-guided RCS Climbing Formwork; in the complicated expansion areas at the pier head, work platforms based on the RCS and SCS Climbing Systems ensured that loads could be safely transferred; in addition, PERI UP reinforcement scaffolds installed around the perimeter provided a safe working environment.
  • The way in which the inclined piers between the Y-pier head and the superstructure were worked on was a special feature of the project: For this purpose, PERI engineers designed a rail-guided finishing carriage based on PERI UP, VARIOKIT and RCS in order to move the entire scaffolding unit hydraulically in 50-cm-increments to the desired position, guided safely via RCS Climbing Rails and Shoes on the inclined pier caps and connected to the structure.
  • The cantilevered parapets on the west bridge were constructed in 24-m-sections using a total of four VARIOKIT Cantilevered Parapet Carriages. These were then fitted with additional PERI UP scaffold suspensions for quality-assuring finishing work and additional scaffolding to create a windbreak wall for wind and weather protection.
  • To speed up the construction sequence considerably, the work platforms were kept available along the entire length of the bridge so that the parapets could be constructed in sections on the eastern superstructure. The project-specific VARIOKIT solution from the PERI engineers also took the additional assembly and finishing platform applications into consideration.
  • The comprehensive service package provided by PERI comprising engineering services, construction site support, chief erectors and factory pre-assembly even included the final construction of the tunnel portals as a transition between the bridge and the tunnel: As the tunnel formwork carriage was also based on the VARIOKIT Engineering Construction Kit with rentable system components, it was possible to develop a customised project solution in no time at all taking into account large-format recesses for sound propagation and sections that had to be formed and concreted on one side, and to deliver it to the construction site and assemble it on site.
