Abstract: |
The joint venture Bau Obervermuntwerk II, consisting of the companies Jäger Bau, Porr, Östu-Stettin and Hinteregger are constructing the pumped storage works Obervermunt II (OVW II) under a contract from the Vorarlberger Illwerke AG between the Silvretta and the Vermunt reservoirs. The Obervermuntwerk II is being built as a parallel works to the existing Obervermuntwerk (OVW). Together with the OVW II, a new headrace is being built for the existing Obervermuntwerk and the existing overground penstock will be demolished. All excavation is being undertaken conventionally by drill and blast; only the surge tank and the pressure shaft will be excavated by raise boring previously excavated mucking shafts. The aggregates for the concrete of the Obervermunt II power station (about 200,000 m³) are being prepared from excavated material as far as possible. A dedicated material processing plant for the project is being operated in Vermunt as well as a batching plant. |
