A breakthrough is when a Tunnel Boring Machine (TBMs) completes its Schedule UG stretch & comes out to the bottom of the shaft. The 1.6 km stretch of the underground section up to this breakthrough was completed in 10 Months.





"This TBM is one of the two machines (TBM) being used for tunnelling the UP line and Down line in the underground section and as completed tunnelling, up to 1.6 km whereas the other TBM has completed 1.5 km from its beginning i.e. Agriculture College. The second TBM will also achieve a breakthrough soon. When breakthrough happened the centre of TBM cutter is just 10 mm offset than the designated location", it added.





"The permissible deviation in the tunnelling is 100 mm. This signifies the accuracy in tunnelling. This was successfully achieved on schedule due to deliberate planning and execution in spite of the challenges of the pandemic COVID 19. Utmost care and precautions were taken while following the COVID protocol", said one official.





"MAHA Metro is doing the tunnelling work of Pune Metro with astute planning and utmost precision. MAHA Metro is committed to complete the work in time", said Dr Brijesh Dixit, Managing Director of MAHA Metro.

Innovative SkyWay technologies: Future Transportation

Image
SkyWay string transport is an energy and transportation communicator of elevated overpass type. It uses electric vehicles on steel wheels riding on specific string rails. The main design differences of this system from other types of railroads of trestle design are pre-stressed tension of the structure, the absence of a continuous solid roadbed, low materials intensity in construction and visual simplicity. The main advantages are economic efficiency, environmental friendliness, durability, reliability, safety and, consequently, high market competitiveness. SkyWay transport is developing in three main areas: high-speed intercity type (up to 500 km/h, and in future, up to 1250 km/h with the transition to a pre-vacuum tube) urban passenger type (up to 150 km/h) and freight type. It has no analogues in its field with the ability to meet the entire range of transportation needs. In future it can be integrated into a unified global energy, information and transportation network, which will ...
