EPB’s have an articulated shield that is sealed against incoming water pressure, and monitor and control the the pressure inside the cutter-head to chamber in order to achieve balance with the pressure in front of the cutter-head – hence the name “earth pressure balance”.

Crossover #TBM are primarily used for projects that have a wide range of geological features to dig through. If a project includes sections of hard rock, soft ground, or boulders then a crossover machine is the best option.

Because broken ground is a safety risk to any boring project, it is important that you use a single shield boring machine, as it has a shield that protects workers from broken rock until tunnel lining can be safely installed.

It consists of a rotating cutter-head which is mounted to the cutter-head support, followed up by three shields. A tail shield, a gripper shield, and a telescopic shield which slides within the larger outer shield.

Double Shield #TBM was invented by the Robbins Company in 1972 as a way to safely take on tunneling projects that pass through fractured rock, something that could not have been done in the past.

The cutter-head is the same size as the tunnel diameter, and the machine works by thrusting disc cutters into the rock while the cutter-head rotates. The combination of high thrust and rotation chips away at the rock allowing the machine to advance with ease.

A Main Beam TBM is great for digging through hard rock. The Robbins company states that if you want to drill through hard rock in the shortest time possible, then the Main Beam machine is the way to go.
