Tunnel boring machine solutions from SKF

Once a tunnel boring machine begins its descent, its inability to backtrack becomes a big liability. If a major breakdown occurs while the machine is tunneling, the resulting down time and repairs can delay construction for many months and send costs soaring. Cutter heads that fail in operation, for example, can result in costly repairs. During tunnel boring machine development projects

Simulation of rock fragmentation induced by a tunnel

Tunnel boring machines (TBMs) have been widely used in tunnel construction for a variety of purposes such as highways and subways. The cutter-head design is one of the critical aspects of the TBM manufacturing process. The head diameter, number of cutters, thrust force, rolling force, penetration depth, and cutter spacing are the important parameters in head design. Among these, the cutting

BORED TUNNELS

A tunnel boring machine (TBM) consists of a shield (a large metal cylinder) and trailing support mechanisms. At the front end of the shield a rotating cutting wheel is located. Behind the cutting wheel there is a chamber where, depending on the type of the TBM, the excavated soil is either mixed with slurry (so-called slurry TBM) or left as-is (earth pressure balance or EPB shield).
