Теперь щит будет разобран и отправлен морем в Россию. А тем временем специалисты СМУ-9 и СтройМехСервиса готовят монтажную камеру для этой машины.
Mosmetrostroy Contractors of Moscow, Russia purchased an 800 tonne, 11m diameter
Earth Pressure Balance TBM from LOVAT Inc. in September 2006.
The TBM, model RME430SE Series 23400 has been commissioned to excavate 150 meter
long escalator tunnels at slopes 30°. The EPB TBM will be capable of a 100m
radius vertical turn, through the use of twin articulation joints (passive and
active) and a cyclical copy cutter. At the completion of the tunnel the TBM is
designed to be disassembled and transported back through the completed tunnel.
The TBM is equipped with a Mixed Face Cuttinghead powered by a Variable
Frequency Electric Drive which includes: Abrasion resistant plating on the
cuttinghead face and rim, LOVAT ripper teeth, interchangeable with disc cutters,
LOVAT Scraper Teeth and 6 No. Independent Injection Ports for Ground
The tunnel alignment is below the water table at a maximum depth of 80m above
the tunnel invert. The anticipated geology along the tunnel alignment is
carbonate rocks and a group of soils including: clay, loam, and loamy sand. The
tunnel lining consist of 6 No. prefabricated concrete segments plus one key
segment with an outside diameter of 10,600mm and inside diameter of 9,400mm.
Muck removal from the tunnel will be accomplished by a high density much pump
In addition to the TBM, Lovat will also supply detailed design of the segmental
lining, segment forms, technical support for the assembly and tunnelling as well
as specialized guidance systems, ground conditioning and back fill grouting
The TBM is scheduled to be delivered in September 2007
