Unforeseen Complications Halting Uttarakhand Tunnel Rescue
The latest update on the Uttarakhand tunnel collapse reveals a temporary setback in the rescue efforts. A critical 2-meter section of the inserted pipe had to be removed due to compression caused by drilling friction. This unexpected development led to a pause in the operations at the collapse site, raising concerns about the timely rescue of the trapped workers.
Technical Glitch with Auger Machine
The rescue operations faced a temporary pause due to a technical issue with the auger machine deployed for drilling through the rubble. Officials reassured the public that the trapped workers would be freed ‘soon,’ but the malfunction of the machine caused an unforeseen halt. Efforts are underway to rectify the technical glitch, and officials have urged the media not to speculate on the timeline for the rescue operation to avoid misleading the public.
Challenges and Solutions: A Detailed Look
Auger Machine Blades and Debris Hindrance
During a media briefing, Mahmood Ahmed, Additional Secretary Technical at Road and Transport, shed light on the technical glitch affecting the machine. A team of experts has been mobilized to address the issue, particularly the damage to the auger’s blades. The debris and metal lodged in the collapsed section of the tunnel are identified as significant hindrances. Cleaning operations are in progress to prevent further complications with the machine.
Weakening Concrete Support
Ahmed mentioned that the concrete supporting the auger machine has weakened due to increased torque and extended distance. The goal is to surpass the 45-meter mark. To reinforce the concrete support, grouting and rock bolting have been swiftly conducted, including the addition of extra concrete mixed with an accelerator for quick strength.
Timely Pipe Repair and Future Plans
Welding a new pipe is anticipated to take about two hours, according to the official. The hope is for a smooth journey forward, and prayers are requested for the same. The team aims to complete the operation within two hours, expressing optimism about the progress.
Overview of the Tunnel Collapse and Ongoing Operation
After a section of the under-construction Silkyara to Barkot tunnel collapsed on November 12, 41 laborers were trapped within a 60-meter stretch on the Silkyara side. The rescue operation, now in its 13th day, continues to face challenges.
Workers’ Confined Space and Safety Measures
The trapped workers are confined within a 2-kilometer segment of the fully constructed tunnel, which includes concrete structures ensuring safety for the individuals awaiting rescue.
NDMA’s Call for Caution and Collaboration
Collaborative Efforts and Government Commitment
Gen. Syed Ata Hasnain, a member of the National Disaster Management Authority, emphasized the collaborative efforts of the state and central governments. He stated that the government is sparing no resources in the challenging operation to save the ‘sons of India’ working in the mountains.
NDMA’s Caution Against Speculation
The NDMA urged the media not to speculate on the timeline for completing rescue operations, emphasizing the complexity of the operation. They highlighted the joint efforts of central agencies and multiple state governments involved in the rescue operations at the Silkyara tunnel.
Despite the challenges and setbacks, the commitment to the rescue operation remains unwavering, with the collective aim of ensuring the safety and well-being of those trapped in the Uttarakhand tunnel collapse.
