    Quieter Construction Methods

Some advanced quieter construction methods have been established. Performance and practicability of the equipment has been studied and approved on different construction sites in Hong Kong.


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.
