How Was the Channel Tunnel Built?

Engineers used two systems of tunnel linings – cast iron segments bolted together and precast concrete rings. The tbms excavated a huge amount of chalk. On the french side, the chalk was crushed, mixed with water, and pumped inland behind a specially built dam 37m high.

How Was the Channel Tunnel Built?

The Channel Tunnel, also known as the Euro Tunnel or Chunnel, is a 31 mile long railway tunnel beneath the English Channel which connects the United Kingdom to France.

It is considered to be one of the most remarkable engineering feats of the modern era, and its construction required the cooperation of two countries and the coordination of hundreds of engineers, workers, and other personnel.

The idea of a Channel Tunnel was first proposed in the early 1800s, but the project was shelved due to a variety of political and engineering difficulties.

It wasnt until the 1980s that a serious attempt at constructing the tunnel was made. The first step in the process of building the Channel Tunnel was the selection of a route for the tunnel.

The route was chosen based on a variety of factors including cost, time, and engineering feasibility. It was eventually decided that a tunnel connecting Folkestone, England, and Calais, France, would be the most suitable.

Once the route was selected, construction of the tunnel began in 1988. It was a complicated undertaking, requiring the use of advanced engineering techniques and the support of two governments.

The first major task was to create a tunnel between the two countries. To do this, two separate tunnels were dugone
