First Mountain Tunnel Formed In Just 10 Months For Mumbai-Ahmedabad Bullet Train
The Mountain Tunnel For The Mumbai-Ahmedabad High-Speed Rail Line Project Was Finished On October 5, Marking An Important Milestone For National High Speed Rail Corporation Limited (NHSRCL).
The Route’s First Mountain Tunnel Was Successfully Constructed In Under Ten Months.
The 350-Meter-Long, 12.6-Meter-Diameter Horseshoe-Shaped Tunnel Is Designed To Fit Both The Upward And Downward Tracks Of The Future Mumbai-Ahmedabad Bullet Train Corridor. Approximately 10.25 Meters Is Its Height, According To An NHSRCL Representative.
The Eventual Mumbai-Ahmedabad Bullet Train Line Will Be Able To Fit Both The Upward And Downward Tracks Inside The 350-Meter-Long, 12.6-Meter-Diameter Horseshoe-Shaped Tunnel. Its Height, According To An NHSRCL Spokesperson, Is About 10.25 Meters.
According To NHSRCL, This Tunnel Was Constructed Using The State-Of-The-Art New Austrian Tunneling Method (NATM), A Technique Recognized For Its Precision And Potency. The NATM Method Consists Of A Series Of Meticulous Steps, Beginning With Marking Drill Holes On The Tunnel Face And Continuing With Drilling, Explosive Charging, Controlled Blasting, Removal Of Muck (Blasted Rock Pieces), And Installation Of Primary Support Elements Such As Steel Ribs, Lattice Girder, Shotcrete, And Rock Bolts. An Official Stated That These Actions Are Tailored To The Unique Geological Conditions That Each Blast Creates.
The Mumbai-Ahmedabad High-Speed Rail Corridor’s Seven Mountain Tunnels Will Be Constructed Using The NATM Method. Transportation In The Region Is Projected To Undergo A Revolution Thanks To The Mumbai-Ahmedabad High-Speed Rail Corridor (MAHSR) Project, Which Features Multiple Mountain Tunnels Constructed Using The NATM Method. With This Groundbreaking Project Moving Forward, High-Speed Rail Connectivity In India Has A Bright Future And Will Improve Connectivity And Travel Efficiency Between Two Significant Cities.
A Track Slab Production Factory At Gujarat’s Anand Was Launched By NHSRCL On October 1. Track Slabs Will Be Needed For The Construction Of The Ballastless Track Works For The MAHSR, And They Will Be Made By This New TSMF.
The Plant, Which Has A Footprint Of 1 Lakh Square Meters, Is Home To Contemporary Machinery Required To Create Track Slabs For The 116-Kilometer Double-Line High-Speed Rail Track For The MAHSR Corridor.
The Project Will Require 45,000 Precast Track Slabs, Which The TSFM Will Produce. 60 High-Precision Molds Have Been Purchased And Installed In This Facility. These Molds Have A Daily Capacity Of 60 Track Slabs. 200 Track Slabs Are Required For Every Kilometer Of Track. It Provides Storage Room For Up To 9000 Track Slabs, Which Makes Track Installation Simpler And More Smooth.
With The Use Of A Concrete Distribution System, TSMF Is Fully Automated. NHSRCL Has Utilized A Number Of Auxiliary Facilities To Help In The Production Of Track Slabs.
