Tunnel Boring Machine (TBM) railsystem

Tunnel Boring Machine (TBM) A tunnel boring machine (TBM) also known as a mole, is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata.They can bore through hard rock, sand, and almost anything in between. Tunnel diameters can range from a metre (done with microTBMs) to almost 16 metres to date.

To excavate the tunnel cavity, the tunnel boring machine will be lowered into shafts to "drill" the tunnel and then removed through retrieval shafts at the end of each tunnel route. Construction trailers, crew parking, trucks, piping materials, generators, a crane, and other equipment will be located onsite.

Horizontal Geotechnical Investigations For Tunneling

Horizontal drilling applications were often limited to specialty testing programs and to perform probe drilling from a tunnel boring machine (TBM) as part of production tunneling. The former often involved cumbersome setups with skid rigs and cribbing in a pilot tunnel or shaft. The latter usually was limited to
