Bypass tunnel Sochi, Russian Federation

Bypass tunnel Sochi, Russia - For construction of the emergency parking bays, the formwork carriage was designed with a width of 14.30 m. Moving the carriage to the next bay through the smaller-sized standard cross-section, required a reduction in the maximum external dimensions.
Bypass tunnel Sochi, Russia - For moving the carriage to the next emergency bay, PERI developed an accurately-defined working sequence by which the formwork segments could be hydraulically folded and lowered.
Bypass tunnel Sochi, Russia - Moving through the reduced standard cross-section resulted in lowering the formwork carriage construction by more than 1 m and folding up at the sides for a width of around 10 m.
Bypass tunnel Sochi, Russia - The electric drive unit provided a fast and easy to operate forward movement of the tunnel formwork carriage.
