In the city of Uttarkashi in Uttarakhand, there are approximately forty workers who have been unable to escape a tunnel that is now under construction for more than twenty-four hours. After visiting the tunnel, the Secretary for Disaster Management Ranjit Kumar Sinha stated that it may take a further two days to rescue the workers who are trapped inside.
Rescue Efforts Ongoing for Trapped Workers 265 Meters Deep in Tunnel
The distance between the workers who were imprisoned and the escape route that was devised to reach them is around sixty meters. According to the officials, the slab that was obstructing approximately 20 meters of the tunnel has been removed, but there is still a route that needs to be cleaned that is 35 meters.
Reprofiling is the act of modifying or adjusting the contour of a structure that is located around 265 meters inside the tunnel. Yesterday, approximately 40 personnel were deployed for the procedure of reprofiling. They were unable to escape because a section of the tunnel approximately 50 to 55 meters distant from them gave way, trapping them within.

After the event was reported, the search and rescue operation got underway right away. One of the most important things for the rescue teams to focus on was making sure that the workers who were trapped had access to food and air.
Unstable Soil Hinders Rescue Operations for Trapped Tunnel Workers
Pipes carried necessities like medications, food, water, electricity, and oxygen into the area that was imprisoned. These piped-in provisions came from the outside. Through the use of Walkie-Talkies, the rescue teams were able to successfully establish communication with the workers.

Initial investigations indicate that a landslide in the area was the precipitating factor in the collapse. The Chief Minister of Uttarakhand, Pushkar Singh Dhami, stated that the debris is falling because of unstable soil, which is causing a delay in the rescue operations.Stabilization work is being done on the loose rubble, which is what is delaying the rescue operations. Additionally, excavation with shotcreting has begun for the first forty meters of the collapsed tunnel.

The process of spraying concrete at a high velocity across a structure is referred to as “shotcreting.” Two significant steps have been taken by the rescue crews in order to evacuate the workers.In addition to removing the loose earth, 21 meters of debris is currently being shotcreted. Due to a very slight collapse of the debris, the depth of the excavation has been lowered to 14 meters.
Daring Rescue Operation to Free Workers Trapped Under Rubble
In order to free the workers who are trapped underneath the rubble, the rescue crews have devised a strategy that involves pushing a pipe with a diameter of 900 millimeters using a hydraulic jack and cutting a hole into the mountain of wreckage. The daring operation is currently preparing to launch, and preparations include gathering all of the necessary materials and machinery. Additionally, professionals from the department of irrigation have joined the operation.
The Chardham Mahamarg Pariyojana includes the construction of a tunnel that is 4.5 kilometers long and connects Silkyara to the axis that runs between Gangotri and Yamnotri. The workers are allegedly safe while they are trapped in a buffer zone that is 400 meters long in the tunnel.
