Smooth construction sequence
with flexible mobile tunnel formwork
The tunnel consists of two parallel rectangular sections, and forms part of the 16.6 km longest Swedish motorway project. This four-lane ring road around Stockholm should lead to a significant relief in traffic in the Swedish capital from the year 2004.
The PERI solution consisted of three wall and two mobile slab formwork units.
The mobile wall formwork is a gallow construction with counterweights on which two TRIO units were suspended. An hydraulic installation provided infinite adjustment to the 0.80 – 1.80 m thick walls.
The mobile slab formwork was carried, in section, by two pairs of props. The adjustment to the changing section widths was made by the individually extendable telescopic beams.
The working sequence could be considerably eased through the high operating comfort of the mobile formwork.,The working sequence could be considerably eased through the high operating comfort of the mobile formwork.
