SBB line DfA 600, km 7.234 Arth Goldau

Over the last 6 weeks, the final part of the stabilisation of the retaining structure 7.234 between Immensee and Arth-Goldau has been completed. The existing retaining structure is being permanently secured with permanent anchors and a shotcrete shell. Coloured shotcrete will be used to match the colour of the wall to the local Nagelfluh. The construction work is being carried out at night and while the neighbouring track is in operation. The drilling work on the retaining structure requires specialists on a suspended cable who can move along a horizontally tensioned cableway.
