How China Built 50,000+ km of High-Speed Rail. Full Documentary on Mega Projects & Construction Tech

Описание: Step inside modern mega construction and heavy engineering—starting at Hope Cement Works, a UK cement plant commissioned in 1929 producing up to 1.2M tons/year. Watch quarry blasting, multi-stage crushing, ball mills, preheater cyclones, and 1450°C rotary kilns using alternative fuels like waste and scrap tires. Then shift underground to Germany’s Petersburg railway tunnel enlargement with a protective inner tunnel, drill-and-blast cycles, shotcrete stabilization, rock bolts, and precision inner lining—all while trains pass every 8 minutes. Explore fibercrete shotcreting for coal mines, rapid urban track demolition, the ultra-smart Gomaco GP3 concrete paver, 20th-floor concrete pouring, precast twin-wall erection, Easy Click foundation formwork, China’s slab-track high-speed rail laying, asphalt milling/paving, tetrapod casting, motor grading, and greener concrete with sugarcane bagasse ash.
