How Underwater Tunnels Work

32 min 9 movies discussed
Listen

It's a pretty amazing feat to dig a tunnel beneath a body of water that's big enough (and safe enough) to drive a train through. While humans have been digging underwater tunnels for thousands of years, it wasn't until the late 19th century that it became viable on a large scale. In this episode, Chuck and Josh explore the ins and outs of the engineering triumph that is digging below water.

AI Summary

In this episode of Stuff You Should Know, Josh and Chuck dive into the fascinating world of underwater tunnel construction, exploring the engineering marvels that allow us to travel beneath rivers, seas, and straits. They break down three main methods used to build these subaqueous passages - from the historic tunneling shield invented by watching shipworms bore through wood, to massive tunnel boring machines that can chew through solid bedrock, to the ingenious immersion tube technique where pre-built tunnel sections are floated out to sea and sunk into place. The hosts also share some impressive examples like Japan's record-breaking Seikan Tunnel and discuss why engineers might choose to go under the water rather than over it with a bridge.
