RAUHES HUS BLØD FORBINDELSE HAMBURG-HORN

For Hamburger Hochbahn AG, OTTO WULFF has implemented a vibration-isolating track support plate in the tunnel structure of the U-Bahn line U4 / U2 directly behind the Rauhes Haus station towards the city center, on behalf of Bahnbau Nord GmbH.

The goal was to isolate the above-ground building complexes from the vibrations caused by the trains passing every 5 minutes. For this purpose, approximately 230 height-adjustable spring elements were installed to create a mass-spring system, in order to raise the 600 m², 40 cm thick reinforced concrete plate by 4 cm and permanently decouple it from the rest of the U-Bahn tunnel structure.

Within 14 days, the track support plate had to be completed and load-bearing for rail installation and train traffic during the prescribed maintenance period. With great teamwork and the cooperative collaboration with the client and the contractor, train traffic could resume as planned.
