Supply of TBM for Oztas Co. - Gûrpinar & Firuzkoy Tunnels, Istanbul
Jun 06, 2007
Turkish contractors Oztas Co. have signed a contract for the supply of a refurbished LOVAT RME136SE Series 19500 Earth Pressure Balance Tunnel Boring Machine [TBM]. The TBM will be utilized in the construction of the Gûrpinar & Firuzkoy Tunnels located in Istanbul, Turkey. The TBM will undergo a complete refurbishment at LOVAT’s facilities in Toronto, Canada, including conformity to European “CE” standards.
The TBM will then bore the 3,770 meter long Tahtakale-Ambarh Wastewater Tunnel in Firuzkoy through three distinctive formations: the Kuºdili Formation, consisting of very soft to firm sandy-silty-clay; the Ceylan Formation, consisting of limestone with marl fragments and clay layers; and also through the Gûrpinar Formation as described above. Groundwater levels will vary from 1 to 48 meters below the surface, with the entire alignment below the groundwater level.
The TBM is scheduled to be delivered to Istanbul prior to year’s end.
