Vorzeigeprojekt für den modernen Brückenbau
Enorme Kräfte sicher beherrschen
Herzstück des Systems ist ein Freivorbauwagen – eine gewaltige Konstruktion aus Stahl mit beeindruckenden Abmessungen: 30 Meter lang, 16,5 Meter breit und 20 Meter hoch. In Kombination mit dem daran angehängten Schalwagen, der als Arbeitsplattform, Schalungsträger und Betonierrüstung dient, bringt das System ein Gesamtgewicht von bis zu 150 Tonnen pro Seite auf die Waage. Diese gesamte Konstruktion wurde bereits erfolgreich auf die finale Arbeitshöhe von 40 Metern über dem Nord-Ostsee-Kanal gehoben – ein komplexer und millimetergenauer Vorgang, der höchste Präzision und Koordination erforderte.
Bridge construction scaffolding system is lifted to working height
The innovative customized bridge construction scaffolding system is lifted to the final working height of 40 m: A cantilevered formwork carriage with an attached formwork carriage serves as a working platform, formwork solution and concreting scaffolding.
Cooperation as the key to success
The armament system used was developed in close cooperation with the experienced partner companies Strukturas and Hünnebeck developed. In an iterative planning process, a solution was created that was precisely tailored to the requirements of the structure, the special conditions of the construction site and the high safety requirements.
The successful implementation of this complex engineering service is the result of an intensive planning, coordination and construction phase. It is a prime example of the expertise and innovative strength with which Implenia realizes challenging infrastructure projects.
Henning Schrewe, Head of Implenia Civil and Special Foundations (ICS) Germany, emphasizes: "The Rader High Bridge is not only a sustainable structure, but also a symbol of modern engineering and successful teamwork. The project illustrates how Implenia is making an important contribution to sustainable and efficient transport infrastructure in Germany through tailor-made technical solutions, interdisciplinary collaboration and the highest quality of execution."
The Rader High Bridge project
Under the technical leadership of Implenia, a consortium is constructing the replacement of the Rader Hochbrücke / BAB A7 highway bridge on behalf of DEGES. The new highway bridge is 1,500 m long and 42 m high and carries the A7 east of Rendsburg, Schleswig-Holstein, over the Kiel Canal and the Borgstedter Enge. The bridge is a steel composite construction and plays an important role for traffic to and from Denmark and Scandinavia.
