double-shield TBM
A double-shield TBM is generally considered to be the fastest machine for hard rock tunnels under favorable geological conditions with installation of the segment lining. It is possible to drive 100 m in 1 day. This type of TBM consists of a rotating cutter head and double shields (Fig.
How do tunnel boring machines turn?
The wheels are turned by friction as the cutting head rotates and hydraulic cylinders push from behind. This thrust is a function of the number and size of the cutting discs. The thrust a TBM can place on a disc goes up with the square of its diameter, according to John Turner, chief engineer at Robbins.
