Back in February when Larsen & Toubro’s tunnel boring machines (TBMs) Avni and Urja were in-transit to Bangalore from China, another Chinese heavy equipment manufacturer, Qinhuangdao Tianye Tolian Heavy Industry Co. Ltd., completed factory acceptance tests (FAT) for 6 multi-service vehicles (MSVs) to support L&T during the 73.92 km Phase 2 project’s construction.
These MSVs each have a capacity of hauling 25 tons and their primary goal will be to support underground logistics – to transport tunnel ring segments from the bottom of the TBM launch shafts to the rear of the TBMs. The muck from tunneling will be extracted through a pipeline since tunneling will be slurry-based.
Larsen & Toubro will deploy these exclusively on the 13.885 km Dairy Circle – Nagawara underground section of Bangalore Metro’s 21.386 km Line-4 (Reach 6 / Pink Line) where it won 2 packages (view map) in February 2019 – the 2.755 km RT-02 package between Vellara Road Station – Shivaji Nagar, and the 2.884 km RT-03 package between Shivaji Nagar Station – Tannery Road.
Meanwhile, here’s a recent snap of the Shivaji Nagar Station from where L&T’s CRCHI Slurry TBMs Avni and Lavi will be commissioned –
