Russia, Moscow - ru/25


CSC Geoton of Moscow has purchased a 3.3 m-diametre EPB TBM from Lovat, model RME137SE, to be used to build the 1,800 m-long Gertsevo cable tunnel in the Strogino region of Moscow, beginning at the Gertsevo power substation. The tunnel will be used for 110-220 kV power transmission lines connecting the substation with the Moscow power grid. The TBM will be erecting 1 m-long rings, composed of six trapezoidal prefabricated concrete segments (ID of 3 m and OD of 3.4 m), with grouting through the segments. The anticipated geology along the tunnel alignment is glaciofluvial deposited fine and medium sands as well as loam. The entire alignment is below the water table to a maximum depth of seven metres above the tunnel invert. Lovat is providing technical services for the coordination, design, procurement, segment design and segment plant. The TBM will be ready to bore in January 2007. Visit www.lovat.com 33-34/06.
