【衝撃】中国の1兆円海底トンネル、開通7分で事故…「100年安全」の看板が崩れた瞬間

China's Shenzhen-Zhongshan Tunnel, a massive underwater tunnel costing approximately 1 trillion yen, was touted as a national pride. It was 24 kilometers long, had eight lanes in each direction, and was designed for a 100-year lifespan. The Chinese government heavily promoted the project, claiming it set multiple world records. However, the first accident occurred just seven minutes after its opening. Furthermore, less than two years after its opening, torrential rains caused flooding inside the tunnel. Why did this massive infrastructure, touted as safe for 100 years, develop problems so quickly? Was "extreme weather" truly the only cause? This video will delve into the construction costs, design philosophy, initial chaos, flooding incidents, and the unseen weaknesses inherent in Chinese infrastructure regarding the Shenzhen-Zhongshan Tunnel. Mega bridges and tunnels may symbolize a nation's power. However, what truly protects people's lives may not be the flashy, visible structures, but rather the less conspicuous aspects such as drainage systems, evacuation designs, and inspection systems. This issue is not unique to China. Is our social infrastructure, including that of Japan, truly safe? Please watch until the end.
