The history of underwater tunnels is surprisingly old. Water tunnels built hundreds of years ago great effort and technique is the product.

Let’s see how long these structures have existed in our lives how it can be built let’s see.

In 1818, a French engineer named Marc Brunel invented a device that allowed workers to dig tunnels under rivers.

This tunnel shield by Brunel had a large rectangular iron wall containing numerous small hatches. The workers opened the hatches one by one to remove several inches of soil and after making some progress all shields were pushed forward.

As the shields move forward a few centimeters at a time, the workers will move behind the tunnel shell He built a thick brick wall. However, this was a very time-consuming job. So much so that it took workers nine years to build this structure.

For example, the tunnel under the River Thames in London became the first underwater tunnel in the world.

But technology has advanced a lot since Brunel’s time. Nowadays, underwater tunnels are generally huge tunnel boring machines It opens with . In addition, these machines cost millions of dollars, but thanks to this large tunnels can be created in a very short time.

Moreover, another new form of underwater tunnel construction is the cut-and-cover method. To use this method, builders search the riverbed or ocean floor They dig a ditch.

They then sink pre-made concrete or steel pipes into these trenches. Workers tie the pipes together after covering them with a thick layer of stone the remaining water is pumped out.

In summary, an underwater tunnel can be built using these two different methods. Although Marc Brunel built the first underwater tunnel, there are tunnels now This is done using the cut-and-cover method.
