According to the site manager, this method cut the construction time in half in comparison to the conventional construction method. ![]() “The great advantage of this construction method is the fact that immediately after the installation of the precast elements, we could start backfilling and placing the tracks again,” Borchert says. Two 13 m long strip foundations are used as the base of the tunnel. After placing, they were bonded with epoxy resin, tensed against each other and installed in the final state firmly fixed. ![]() These precast elements are box segments, which were manufactured in the match casting method at the concrete block factory of Kleihues located in Emsbüren. Once the track bed had been removed and about 800 m³ of soil had been excavated, a mobile crane was used to position four precast elements weighing up to 47 tons in a depth of approx. The time usually required for the construction of a temporary structure, could be used for the actual building structure. Using this construction method spared the company the necessity of doing elaborated pit lining, building temporary bridges and casting of in-situ concrete. So as to manage with just one track possession from the last train on Friday night to the first one on Monday morning, we quite consciously opted for precast concrete elements for the construction of the pedestrian underpass,” states René Borchert, site manager at the building contractor W. “The underground construction, among others, was our part. The time frame which had to be kept was the crucial point in the overall construction project. The new underpass will provide for safe and barrier-free access, thus connecting the town center and the industrial area in an even better way. The planners in charge decided to use precast concrete elements for the construction of the underpass in order to keep the disruptions of the rail operations to a minimum. The construction of a barrier-free pedestrian underpass with two elevators to the central platform is an important part of the rehabilitation measures. In order to meet the associated requirements in the long run, the station situated in the canton of Schaffhausen will be refurbished until the end of 2015. The European Union has classified this route as a Trans-European Network line or TEN line. The station in the Swiss town of Thayngen is part of the railroad line from Zurich to Stuttgart.
