How Russians Built Cable-stayed Bridges. Full Documentary on Mega Construction & Bridge Engineering
From Seattle’s legendary “Bertha” TBM comeback to extreme Swiss Alps pressure-shaft tunneling, this video dives into the engineering decisions, repairs, and breakthrough methods that keep mega projects moving. Watch how crews fight 10-bar water inflows with injection shields, resin grouting, shotcrete, and steel ribs, then shift to pumped-storage powerhouse caverns, high-voltage grid links, and heavy component logistics. We also cover Himalayan highway upgrades, record cable-stayed bridge building, precast girder installation, concrete production, crushing plant manufacturing, micropile stabilization, asphalt repair tech, HDD seabed pipeline drilling, precision demolition, and heavy-haul convoys.
