To use this method, builders dig a trench in the riverbed or ocean floor. They then sink pre-made steel or concrete tubes in the trench. After the tubes are covered with a thick layer of rock, workers connect the sections of tubes and pump out any remaining water.
How to Build Underwater Tunnel?
Building an underwater tunnel is a complex and expensive process that requires a great deal of expertise and engineering know-how. While there are several types of underwater tunnels, this article will focus on the most common type – a concrete box tunnel, which is the most widely used for constructing undersea tunnels.
The first step in building an underwater tunnel is to plan the route and determine the total length of the tunnel. This is an important step that needs to be carefully considered, as the route of the tunnel will affect the cost and safety of the project. Once the route is determined, the next step is to begin the actual construction of the tunnel.
The tunnel construction process typically begins with the construction of a concrete box or “casting bed”, which is the foundation of the tunnel. This bed is built by pouring concrete into a formwork or mould and then reinforcing it with steel or other strong materials. This casting bed will form the walls and ceiling of the tunnel, and will be the first layer of defense against water pressure and other elements.
The next step is to build the walls and ceiling of the tunnel. This process involves building the walls from concrete, steel, or other materials. Depending on the size and length of the tunnel, the
