Tunnel Boring Machine - an overview ScienceDirect Topics
Aug 18, 2010 As the use of TBMs and micro-tunnel boring machines (MTBM) increases with advancements in tunneling technology, contractors are more and more willing to tunnel in difficult ground conditions.As a result, there have been a number of cases of tunneling machines becoming stuck or breaking down. In order to facilitate the repair and/or “rescue” of the tunneling machines and get the
Tunnel boring machine - Wikipedia
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 may also be used for microtunneling.They can be designed to bore through anything from hard rock to sand.Tunnel diameters can range from one metre (3.3 ft) (done with micro-TBMs) to 17.6 metres (58 ft) to date.
