This is because the bridge deck is concreted about 35 cm above the final position and then lowered onto the bridge bearing. "We could only solve this with the Doka UniKit primary & secondary beams, which are not as high, but have an extremely high load-bearing capacity," says Torres. "In addition, Doka pre-assembled the main and extension girders in a safe lying position and then lifted them in pairs. This meant that the necessary duration of closure of the motorway was much shorter."
From the bridge, heading south, we enter a 170 m long supply shaft, which is formed with our Framax Xlife wall formwork, and continue into an 80 m long tunnel, which is partly in cut-and-cover and mining construction method. Here, we use our SL-1 tunnel traveller for both tunnel types without conversion work.
The new Västlänken link station "Centralen" is being built north of Gothenburg's current central station and right next to the of the Nils Ericson terminal. Apart from the section of the Västlänken that runs through Gullberget, the ground on this consists of soil and clay. The area of the western connection will be temporarily excavated for construction of the tunnel and covered upon completion so that the land above can be used for other purposes. For this section, we supplied Load-bearing Staxo 100 to support the slabs, Framed formwork Framax Xlife and Supporting construction frame Universal F for the walls (wall high: 7.6-9.3 m, slab thickness: 1.5-3.5 m).
