The Project:
Extension of the pumped storage power station at Vianden by an 11th machine, Lot 1 – Structural installations, Luxemburg
Companies involved:
Ed. Züblin AG, IU Directorate - Tunnel Construction, Stuttgart
Strabag AG, IQ Directorate, Vienna
Jäger Bau GmbH, Schruns
The largest pumped storage power station in Europe in the township of Vianden in Luxemburg, with a peak capacity at the present time of 1,100 MW, is being extended by a further turbine with a capacity of 200 MW. The construction work includes the carcase work for the cavern, as well as the access galleries, shafts, and intake and outlet structures.
The Problem:
Fresh water supply by means of submersible pumps for the washing area, drill carriages, etc. Keeping the water clear by means of submersible pumps during the driving of the tunnel.
The Solution:
Use of Tsurumi dirty water pumps of widely differing types: KTZ22.2, KTZ35.5, KTZ47.5, tough, robust pumps in cast iron design for clearing water from the drift or heading face, KRS2-150 with stirring mechanism for sludge disposal, and LH25.5W high-pressure pump for removing water from the entire tunnel stretch.
