Tunnel Boring Machine

With a large rotating metal cutter head, tunnel boring machine can pass through different type of soil, rock or soil-rock mixture. Tunnel boring machine is a multi-functional construction equipment which can excavate, remove excavated materials and install the precast segment immediately to make a permanent tunnel wall.  Unlike cut and cover method, construction work using a tunnel boring machine takes place mainly underground, which significantly reduce noise, dust and disruption to nearby NSRs.
