The Tunnel Boring Machine (TBM) features crucial mechanical elements such as main bearings that support the rotating cutterhead, allowing it to excavate efficiently. Erector bearings play a pivotal role in the tunnel lining process, supporting the erector arms responsible for placing concrete segments to form the tunnel walls. Hydraulic pumps power essential functions like the movement of the cutterhead and the operation of erector arms, providing the necessary force for excavation and tunnel li

🏗 Since it’s construction, our purpose built precast facility in Benalla has been hard at work creating concrete segments that will line the West Gate Tunnel. At capacity, it can produce up to 1500 tonnes of concrete per day which will also be used to build other parts of our project including new bridges, our elevated road over Footscray and noise walls along the West Gate Freeway. | West Gate Tunnel Project

The drill and blast method in tunnelling involves drilling a series of holes in a precise pattern, then filling them with explosives to break and remove rock. The design of the drill and blast pattern is crucial, as it determines the effectiveness and safety of the operation. It factors in rock type, tunnel size, and desired fragmentation. Proper sequencing and timing of blasts are essential to minimise vibration, control overbreak, and maintain the tunnel's structural integrity. Follow us at tu
