2021-5-21 Kids’ Guide to Building Tunnels. How do we build tunnels? Digging tunnels involves some very special engineers. And how they dig tunnels depends on what they have to tunnel through. If a tunnel is going through hard rock, explosives can be used to blast a way through.
Encourage your budding engineer to imagine the location of their tunnel and how it can be helpful to people, as well as aesthetically pleasing. This creative activity is a great way to introduce children

2020-4-10 Tunnel boring machines are often used to excavate major tunnels. These huge machines can bore through all kinds of sand, clay and hard rocks. The largest tunnel boring machines feature diameters of over 14 metres (46 feet). When dealing with water crossings, building a tunnel is usually more expensive than building a bridge.

Student teams design and create model tunnels through a clay mountain, working within design constraints and testing for success; the tunnels must meet specific design requirements
Digging tunnels is hot, dirty, dangerous work. Since ancient times, tunnel diggers have used different types of tools to carve through mountains and bore through oozing mud.
The tunnel engineers' term for building a tunnel is driving, and advancing the passageway can be a long, tedious process that requires blasting, boring and digging by hand. In the next section, we'll look at how workers drive tunnels through soft ground and hard rock.
