Uttarakhand tunnel collapse: On Friday, the sixth day of rescue efforts to free 40 workmen buried beneath the debris of the collapsed tunnel on the Char Dham path in Uttarakhand began. The task of locating and freeing the trapped workers from the wreckage of the collapsed tunnel started by a powerful drilling equipment.
A six-meter segment of steel pipe had placed into the bored channel, according to officials. It welded to another part.
With the aid of the enormous drill, it intended to gradually insert pipes with diameters of 800 and 900 mm until an escape route made for the workers who trapped past the collapsed section of the tunnel that still under construction.
This is a 5-point guide on the collapse of the Uttarakhand tunnel.
- 1) Experts from Norway and Thailand were consulted due to the unstable nature of the mountains where the collapsed tunnel is situated, and they estimated that around 50 meters of rubble would need to be broken through in order to implant the tubes for evacuation, according to India Today.
- 2) On Wednesday, IAF’s C-130 Hercules aircraft transported the US-made auger machine, in sections, from Delhi to an airfield 30 kilometers distant in case the smaller drilling equipment was unable to complete the task. According to PTI reporting, the 25-ton piece of equipment erected over night.
- 3) During his visit to the rescue site, Union Minister of State for Road Transport and Highways V K Singh established “two or three days” as the “outer limit” for the new equipment to complete the task.
- 4) With an air of optimism, Uttarakhand Chief Minister Pushkar Singh Dhami said that all tunnel projects in the state will now evaluated.
- 5) “I’ve informed that the new drilling apparatus already broken through the rubble five to seven meters. Drilling at a rate of five to ten meters every hour, we expect it will soon reach the trapped workers,” Dhami informed the journalists.
