Tunnel Boring Machineid Common Problem

Q5.How fast does a tunnel boring machine go ?

Tunnel boring isn't an easy job. The TBM uses 25,000 bhp (18,600 kW) and moves at a speed of about 35 ft (10 m) per day. Though the system is largely automated, Bertha still needs 25 people at a time to keep it going.

Q6.Are Tunnel Boring Machines Reused ?

The reuse of machines can, if done to exacting standards, reduce costs and time to deliver. ... International guidelines have been developed to standardize the process of reusing a TBM for another project.

Q7.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.
