Lucknow Metro’s first TBM breakthrough
Workers and officials from the Gulermak-TATA Projects JV, representatives from TBM manufacturer, TERRATEC, and officials from the Lucknow Metro Rail Corporation (LMRC) have witnessed the successful completion of Lucknow Metro’s first TBM-driven tunnels on Phase 1 A, part of its 22.88km-long (Phase 1 A) Lucknow Metro North-South line in Uttar Pradesh, India.
The first of two 6.52m diameter TERRATEC EPBMs working on the project, the S52 TBM named ‘Gomti’, was launched from Sachivalaya Station’s Bapu Bhawan Shaft in January. It took Gomti just four months to complete the first down-line tunnel on the line’s 3.44km LKCC-06 underground section, arriving at Hazratganj Station in late May (see map below).
