Microtunneling Wikipedia

Microtunneling or microtunnelling is a digging technique used to construct small tunnelsThese small diameter tunnels make it impossible to have an operator driving the machine itself Instead, the microtunnel boring machine (MTBM) has to be operated remotely from a control room Microtunnel boring machines are very similar to normal tunnel boring machines (TBMs), but on a smaller scale
