Microtunnel Boring Machine Systems, MTBM, Slurry Microtunneling, Micro-Tunnelling
OVERVIEW. Microtunnel Boring Machines (MTBMs) install gravity flow pipelines that require precise line and grade in poor soil. Microtunneling is a remote-controlled, continuously supported pipe jacking method.
Pipe jacking is a specialist tunnelling method for installing underground pipelines with the minimum surface disruption. Primarily used for new sewer construction it is also used for sewer replacement and relining, gas and water mains, oil pipelines, electricity and telecommunication installations, culverts and subways.
