Mumbai-Ahmedabad Bullet Train: Third Hill Tunnel Successfully Excavated, Major Boost for Project
मुख्य बातें
- •The third hill tunnel under the Mumbai-Ahmedabad Bullet Train project has been successfully excavated in Maharashtra’s Palghar district.
- •The tunnel is 417 meters long and 14.4 meters wide, designed for bidirectional train movement.
- •Controlled drilling, blasting, and advanced monitoring techniques were used in its construction.
- •Three hill tunnels in Maharashtra completed in the last five months; out of eight planned tunnels, seven will be in Maharashtra and one in Gujarat.
- •Preparations underway to launch Bullet Train operations by August 15 next year; the 508-kilometer route will have a speed of 320-350 km/h.
The Mumbai-Ahmedabad Bullet Train project has achieved another significant milestone. The National High-Speed Rail Corporation Limited (NHSRCL) has completed the excavation of the third hill tunnel in Maharashtra’s Palghar district. The tunnel has been constructed in Ambresari village of Dahanu taluka. This success is expected to further accelerate the construction work of the project. The tunnel is 417 meters long and 14.4 meters wide, designed to accommodate trains running in both directions of the Bullet Train corridor.
The excavation of the tunnel was carried out using controlled drilling and blasting techniques from both ends. Special emphasis was placed on safety and quality during construction. Modern technologies were employed to continuously monitor the tunnel’s durability and its impact on surrounding areas. Advanced monitoring systems and geotechnical instruments, including surface settlement points (SSP), 3D targets, strain gauges, and seismographs, were installed for this purpose. A real-time monitoring system was used to track vibrations, ground conditions, and the impact on nearby buildings during the tunnel’s construction.
