Research, development and training underground
The research infrastructure of the University of Leoben on the Styrian Erzberg is unique in Europe. In the "Zentrum am Berg" everything revolves around the construction and operation of underground facilities. The facility is used for research and development purposes, tests and practice operations - and all this under real conditions.
The "Zentrum am Berg" consists of two parallel road tunnels, two parallel railroad tunnels and a test gallery. To efficiently construct the two different cross-sections (railroad tunnel - clear width = 7.52 m / clear height = 7.19 m and road tunnel - clear width = 10.21 m / clear height = 8.22 m), the construction company Swietelsky Tunnelbau GmbH & Co. KG used a formwork concept that had been worked out with the experienced Doka technicians. The supporting construction was designed in a way that it can be used for both the railroad tunnel and the road tunnel with just a few modifications. The shaping formwork was produced using Large-area formwork Top 50. Due to the different inner radii (railroad tunnel = 4.84 m and road tunnel = 6.82 m), the elements were specially manufactured for both cross-sections.
To keep the work on the site as low as possible, all the large-area formwork elements and the Heavy-duty supporting system SL-1 (in transportable units) were pre-assembled by the Doka Ready-to-Use Service St. Martin and delivered to the site. Construction of the railroad tunnel got underway.
