| Re: Dmrc Tunnel Projects
The DMRC has a Tunnel Boring Machines project. The Tunnel Boring Machines are used to excavate tunnels in virtually all types of grounds and under widely different physical conditions. The history of TBMs started with soft ground shields of the type developed in England. These shields progressed by breaking the excavation in to small compartments excavated by hand. The science of mechanical underground tunnel excavation has developed continual step by step. TBMs, also known as Moles, are the recent development in the tunnel driven techniques The contract CC04 is part of the new 58 km long PINK LINE (Line 7) of the Delhi metro phase III project, runs from Mukundpur in the North of Delhi in circle up to Shiv Vihar in the North East. In this project, the first 2 Earth Pressure Balance Machine (EPBM) launched at Azadpur station south Journal of Geomatics Scope of work: The scope of the work consists of: Tunnel: 5.2 km bored tunnels with ID 5.80 meters (using 4 TBM EPB Mode) Cross passage: 1 Nos Emergency exits: 2 Nos Underground stations: 1 No (252m length) Cut & cover tunnel: 1 No (96m), Ramp: 1 No (192m) Get info about 19 Tunnel boring machines boring tunnels simultaneously the national capital`s surface DMRC:   List of 19 Tunnel boring machines boring tunnels simultaneously the national capital`s surface: Phase 3 corridor Location of TBM No. of TBMs Central Secretariat Kashmere Gate Kashmere Gate to Lal Quila 1 Jama Masjid to Delhi Gate 1 Majlish Park Shiv Vihar Azadpur to Mukundpur 2 Delhi Cantt. to Naraina 1 Bhikaji Cama Place to Sarojini Nagar 2 South Extension to Lajpat Nagar 2 Janakpuri West Botanical Garden Dasrathpuri to Dabri Mor 2 Terminal 1 IGI Airport to Shankar Vihar 2 Munirka to RK Puram 2 2 IIT Hauz Khas 1 Hauz Khas Panchsheel Park 2 Kalkaji Mandir Nehru Enclave 1 |
