Fully Hydraulic Crawler Driven Formwork Carriage for Varying Tunnel Cross-Sections
The A26 is one of the most important infrastructure projects to relieve the traffic congestion in the Austrian city of Linz and its surroundings. This also includes the construction of the approximately 300 m long new Danube bridge. A significant proportion of the bridge approaches will be constructed underground to additionally reduce noise and pollution in the city area.
Since May 2020, tunnel construction work has been underway to the north and south of the Danube for the future accesses and exits of the suspension bridge. Five different tunnel cross-sections, the profile transitions, the tight radii between 50 m and 750 m in the bends and the various gradients were just some of the challenges in constructing the 1600 m long access tunnels. Austria's first fully hydraulic crawler driven special tunnel formwork carriage was used for the expansion. This formwork carriage was designed and built by the German company Peri, one of the largest international...
