How Humans Drill Tunnels Under the Ocean Floor #Engineering #documentary
Submarine tunnel construction is one of the most extreme engineering challenges ever attempted — combining Tunnel Boring Machines, ground freezing, immersed tube technology, and high-pressure excavation deep beneath the ocean floor. In this video, we tear apart the entire process layer by layer: geological surveys, TBM cutterhead mechanics, segment erection, waterproofing systems, and the real-world tunnels that pushed the limits of human capability. If this kind of deep-dive engineering breakdown blows your mind — subscribe now and hit the bell so you never miss an episode. #SubmarineTunnel #TunnelBoringMachine #MegaEngineering #UndergroundConstruction #CivilEngineering
