Go Deep. Convey Smart. The Sandwich Belt for Tunneling: A Smarter Approach to Muck Handling in Tunneling
Tunneling is one of humanity’s oldest engineering practices, dating back to prehistoric times when early humans expanded natural caves for shelter and protection. The Babylonians were among the first to apply tunneling to irrigation, channeling water to sustain agriculture and strengthen their civilizations. Later, in ancient Greece and Rome, tunnels played a vital role in transforming marshlands into fertile ground, paving the way for new settlements.
Today, tunneling remains indispensable to modern infrastructure. The International Tunnelling and Underground Space Association notes that contemporary tunnels serve a wide range of social and economic purposes, especially as cities grow denser. They enable clean water distribution, reduce pollution and noise, and make urban living more sustainable.
With ongoing technological advancements, tunneling continues to evolve becoming faster, safer, and more efficient. Discover how Sandwich Belt high-angle conveyors enhance tunnel operations, offering significant advantages for the rapid and reliable removal of muck during excavation.
