Australian manufacturer TERRATEC Tunnel Boring Machines (TBMs) have secured the underground works contract for Pune Metro’s Line 1, Rail Analysis India reports.

Gulermak-Tata Projects Limited selected the tunnelling and underground space technology company to provide with 6.61m diameter Earth Pressure Balance TBMs (EPBMs) for two underground projects for the new metro line 1.

The TERRATEC EPBMs would consist of robust mixed-face dome-style cutter heads which are designed to effectively work in the compact Basalt at the pressure of up to four bar.

As the TBMs make progress, they would be installing 1,400 mm wide by 275 mm thick precast concrete lining rings which consist of five segments and a key. The latest order comes after the excellent performance of two 6.52m diameters TERRATEC EPB’s used by the Gulermak-Tata Project JV on the Phase 1A of Lucknow Metro two months ahead of schedule.

The company has delivered 22 TBMs in India in the last six years. Earlier, TERRATEC had won orders for the Phase III of Delhi Metro Phase, Lucknow Metro, Ahmedabad Metro and Mumbai Metro.
