Boretunnels

Boretunnels, also known as bored tunnels or tunnel boring machine (TBM) tunnels, are underground transportation routes constructed using a specialized machine called a Tunnel Boring Machine. This method involves a large, cylindrical machine that excavates the ground and simultaneously installs the tunnel lining. The TBM operates by rotating a cutterhead at its front, which breaks up the rock or soil. Spoil, or excavated material, is then removed from the tunnel face, typically by conveyor belts. As the TBM advances, pre-fabricated concrete segments are assembled behind it to form the permanent tunnel lining. This process allows for the construction of long, straight, or curved tunnels with a consistent diameter and a smooth, finished interior. Boretunnels are commonly used for subways, railway lines, and road tunnels, particularly in urban environments where minimizing surface disruption is important. The TBM can be adapted to bore through various geological conditions, from soft clay to hard rock, making it a versatile tunneling technique. The primary advantage of boretunneling is its ability to create tunnels with minimal impact on the surrounding ground surface, reducing the need for extensive open-cut excavation and subsequent backfilling.
