Types of Tunnels - TSV
Tunnels are classified by purpose (road, railway, waterway, etc.), construction location (mountain, urban, underwater, etc.), and construction method (mountain tunneling, shield tunneling, cut-and-cover, immersed tube, etc.). Japan is one of the world's leading tunnel countries with approximately 15,000 tunnels. Tunnel technology is essential for transportation infrastructure development, enabling safe and efficient movement.
