Recently your TBM Urja, made a breakthrough after completing a section of 855 metres from Cantonment to Shivajinagar stations, could you take us thru the challenges and how you overcame them.

First of all, Bengaluru metro project is recognized as one of the most difficult TBM tunnel works around the world with frequent stratum variations. The total section is a distance of 855 meters, among them 250 meters upto 200MPa full face hard rock and 350 meters boulders and bottom hard top soft ground encountered; the balance 255 meters consisted of silt or backfill stratum. Apart from that, TBM passed through the oldest settlements of Bengaluru city with a minimum 7.6 meters shallow overburden, which made much more challenging. Based on the difficulties, CRCHI has carried out a number of specific designs for this Hard rock slurry TBM to ensure smooth tunneling under complicated geological conditions such as heavy duty cutter head, 19 inch disc cutters, active articulation + stabilizer, Advanced geological detecting, EMS etc.

Due to the Pandemic, CRCHI has met a lot of difficulties such as no flight and visa termination. But CRCHI took quickly actions and organized local service team supporting the project for assembling, commissioning, test drive and trouble shooting etc., and then the entire Chinese experts reached to strength the backup. Since the last 2 years, CRCHI has continuously provided service to our clients.

Thanks for the efforts of L&T and CRCHI team, URJA (DZ670) made the breakthrough as the first TBM in all of 9 TBMs in this project. TBM VINDHYA (DZ672) is estimated to make a breakthrough early of Oct.
