TBM Design Considerations: Selection of Earth Pressure Balance or Slurry Pressure Balance Tunnel Boring Machines. Rick P. LOVAT, P.Eng 1 1 President & CEO, LOVAT Inc. ABSTRACT In order to determine the specification of the machine to offer a Tunnel Boring Machine (TBM) supplier requires a minimum amount of information.
The TBM makes use of the concrete rings using hydraulic rams which are at the back of the cutter. Once the machine has moved sufficient distance the next concrete ring is installed. Crossrail’s concrete tunnel lining is designed to last 120 years.
The TBM is a full-face boring machine for stable ground such as mountain tunnels. It is available in three configurations: the open type, which utilizes direct counterforce against the ground for forward progression; the full shield type, which progresses by utilizing the counterforce of the tunnel walls while providing full protection for the machinery internals; and a third configuration ...
