LUCKNOW, India: Excavators began drilling with heavy machinery on Tuesday (Nov 14) to fix a wide steel pipe that will help pull out almost 40 Indian workers trapped inside a collapsed Himalayan highway tunnel that caved in two days ago in the north Indian state of Uttarakhand.
The tunnel, which was being built on a national highway that is part of a Hindu pilgrimage route, caved in around 5.30am on Sunday (2400GMT on Saturday).
“We have been supplying food, water and oxygen to the trapped labourers and the officials are in continuous touch with all of them,” Devendra Singh Patwal, a disaster management official said.
Excavators have been removing debris for two days to carve out a path to reach the workers and had been awaiting delivery of a wide steel pipe which will be pushed into an opening of excavated debris to safely pull out the workers.
Patwal said it was not easy to ascertain the time required to pull out the workers.
A team of geologists from the state government and educational institutions had arrived to determine the cause of accident, he added.
