NEW DELHI: India is seeking advice from a Thailand company that helped rescue children from a flooded cave in 2018 as it races to evacuate 40 workers trapped inside a collapsed tunnel in Uttarakhand.
Officials have “contacted the Thai company which rescued the children trapped in the cave”, the Uttarakhand said in a statement.
The state government was referring to the miraculous operation in Thailand to rescue 12 boys from a junior football team and their coach who were trapped for more than two weeks in the Tham Luang cave complex.
Authorities have also asked for help from engineering experts in soil and rock mechanics at the Norwegian Geotechnical Institute as frantic efforts to rescue the workers entered the fourth day on Wednesday.
Earlier today, a heavy drilling machine was airlifted from New Delhi to replace the “failed” equipment which was being used earlier to create an escape passage for the workers,
The new machine, that landed at Chinyalisaur, over 30 kilometres from the tunnel on the Chardham route, is being put into service, amid apprehension by workers at the site on the progress of the multi-agency rescue operations.
Workers chanted slogans at the mouth of the tunnel on the Brahmakhal-Yamunotri National Highway, protesting over the “slow” pace of the operation to rescue their colleagues trapped inside for over 72 hours now.
The plan was to use an ‘auger machine’ to drill through the rubble of the tunnel’s collapsed portion and insert 800-mm and 900-mm diameter sections of mild steel pipes — one after the other. Once this happens, the workers trapped on the other side of the rubble can crawl out to safety.
But the first drilling machine turned out to be too slow and technical issues developed, the officials said. Also, falling debris inside the tunnel damaged the equipment and injured two rescue workers on Tuesday.
A portion of the tunnel, part of the ambitious Chardham All-Weather Road project, collapsed on Sunday. The 30-metre collapsed section is 270 metres from the mouth of the tunnel from the Silkyara side. Officials said the labourers were safe, and oxygen, electricity, medicines, food items and water were being supplied to them through pipes.
