Indore Launches First TBM for Underground Metro Construction
Indore is building part of its metro railway underground.
A huge machine called Narmada will dig the tunnel.
It weighs about 410 tonnes, which is as heavy as many large vehicles together.
Workers assembled it above ground and carefully lowered it into a deep shaft near the airport.
Special lifting equipment was used to move the machine safely.
The tunnel will connect the Airport area with Bada Ganpati.
The machine can help workers build underground in a controlled way.
This may reduce the need to dig up many roads and areas at the surface.
The first Tunnel Boring Machine, named Narmada, was launched for Indore Metro’s underground construction.
The TBM will build the underground metro tunnel between Airport and Bada Ganpati.
The 410-tonne machine was assembled above ground before being lowered into an airport shaft.
A Megalift System and Strand Jack Assembly handled the lifting and lowering operation.
Officials said the launch will accelerate tunnelling while reducing extensive surface excavation in built-up areas.
