RAUHES HUS MYK 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 heading towards the city center.

The goal was to isolate the above-ground buildings 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 separate it from the rest of the U-Bahn tunnel structure.

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