URL More about Roßhag Pumped Storage Power Plant
History of the Power Plant Since Roßhag power plant is located in an avalanche-prone area, it was necessary for the entire construction to be carried out with appropriately solid material, whereby the construction elements are able to withstand a pressure of 20 to 50 t/m². A total of ten deep borehole explosions had to be carried out in the excavation of the construction pit. The building is in paint-ready, in-situ concrete, supplemented by prefabricated concrete units, executed and divided into three blocks of roughly equal lengths by means of expansion joints. The roof over the machinery hall comprises prefabricated, reinforced concrete components. The uphill-facing distribution lines were embedded in a solid concrete block. Strain was nevertheless caused by the encasing in concrete of the pumps and turbine coils, as well as the firm anchoring of the building with the rock. In the surface construction, pillars were covered with concrete at intervals of some 6 m and connected via two 8 or 15 m reinforced concrete girders that lay across the operating floor. The lower girder is connected to the rock by means of high tensile bars; the upper girder serves for slope stabilisation and simultaneously forms the uphill support for the roofing slab. The flat roofs are landscaped with vegetation. The concrete surfaces have a light-coloured interior coating; the floors of the machinery hall and the upper part of the walls are clad with red clinker slabs. The closures are designed as armoured doors.
