In tunnel mechanization drilling uses the Tunnel Boring Machine, which is called TBM for short. Tunnel walls are reinforced by prefabricated concrete components known as concrete segments. These segments are in the form of puzzle pieces of a ring-shaped wall that are placed next to each other with the help of polymer pieces and finally form a concrete ring so that each ring is connected to the adjacent ring by the corresponding polymer pieces and as a result, The sum of the interconnected rings forms a conventional tunnel-like piece.
