​How Metro Tunnels Are Actually Built? | Inside a TBM (3D Animation)

Have you ever wondered how massive Metro tunnels are built right under your feet without disturbing the buildings above? 🚇🏗️ ​Aaj ki video mein hum deep dive karenge Tunnel Boring Machine (TBM) ki engineering mein. Yeh 100-meter lambi aur 1700-ton bhaari machine zameen ke neeche kaise kaam karti hai? Hum dekhenge ki kaise engineers hawa, paani aur aag (fire) jaisi chunautiyon se ladte hain taaki humari ride safe rahe. ​Purely explained using high-end 3D Animation to show you the hidden world of underground engineering. ​⏱️ Video Chapters: 0:00 - The Hidden World Under Our Feet 0:45 - Meet the TBM (The 1700 Ton Monster) 1:30 - How TBM Digs & Builds Rings? 2:15 - Why Don't Buildings Collapse?
