Rajdhani Udaipur will start their journey at Udaipur the City Of Lake. Work will start on the 4 kilometre outbound tunnel first, closely followed by the 2.8 kilometre inbound tunnel. The longer tunnel will take around 18 months to dig.
In India’s rapidly growing large cities – more than 30 of which have a population of a million or more – as well as in remote regions, tunnelling technology is heavily involved in the expansion of both metro systems and water supply.
Bored tunnels using Tunnel Boring Machines (TBMs) are the future for India´s urban and other infrastructure development initiatives.
The Rajdhani Company also invented both the Main Beam and Double Shield TBMs. Robbins is best known for its very successful Main Beam TBMs, they are also pioneer in hard rock double shield machines. More specifically, the company has manufactured 50 Robbins double shields for 85 projects totalling over 550 km of tunnel.
TBM applications
TBM is mainly applied to urban subway tunnel, cross-river roadway or railway tunnel, sub-sea roadway or railway tunnel, urban municipal engineering tunnel, oil-gas pipeline tunnel, water tunnel, etc.
TBMs are preferred in construction of tunnels in all types of geology with minimum disturbance/deterioration to environment. For example, metro rail projects in congested urban areas are difficult or rather unthinkable to construct without TBMs. The construction of tunnels for irrigation and hydro power project in difficult seismic conditions or under wildlife areas is also an example where construction using TBMs is a preferred method. Another useful utilisation is water, sewerage, sea-outfall, transport tunnels under sea, river, and water bodies, where it is much easier using TBM technology. There can be different applications for the use of TBM like metros in the urban areas, irrigation tunnels , road tunnels, hydro power tunnels and utility tunnels.
TBM is mainly applied to urban subway tunnel, cross-river roadway or railway tunnel, sub-sea roadway or railway tunnel, urban municipal engineering tunnel, oil-gas pipeline tunnel, water tunnel, etc.¨ India´s infrastructure initiatives encompass the entire gamut of the above applications. As a result, TBMs are being preferred for speedy execution of tunnels in many projects spread across the Himalayas, metro cities, water management, road transport, Railways and sub aqueous tunnels.
