Chamera H.E. Project (HP) India
Chamera Hydro Electric Project, Himachal Pradesh, India
Power Tunnel for Chamera Hydroelectric Project, India. 9.5 M finished diameter horse shoe shaped Power Tunnel, including large scale drilling. blasting and excavation in rock, concrete lining, cement and sand grouting. steel supports and anchor bolting .
Driving of 760 M length of 10.50 M excavated diameter Headrace Tunnel, from one face, was achieved in a short span of six months. This is the maximum sustained rate of progress in tunneling done by any agency in the Himalayas, so far. A record length of 48 metres of tunnel was driven in a matter of7 days.
The construction of tunnels at Chamera was fully mechanised, using the latest tunnelling equipment, including hydraulic drilling and rock bolting jumbos, low profile hydraulic dumpers, shotcreling machines wilh robot booms etc. The tunnels were excavated in most difficult geological conditions, in an area of reverse faulting and thrusts, typical of the Himalayan foothills. A milestone of the Project was the Tail Race Tunnel crossing 40 M below the bed of a major Indian river “Ravi" . This is the largest under-river tunnel crossing in the Himalayas.
