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

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

There are many methods of tunnel construction, each requiring specialist skills and equipment. These include techniques such as bored tunnels using Tunnel Boring Machines (TBMs), sprayed concrete lined tunnels, tunnels constructed by blasting with explosives, and tunnels constructed by pipejacking. This large variety means the tunnelling world and the skills it needs are constantly varied and challenging. Video credit: @aryan_rajput361 tunnel.engineering #tunnelengineering #artoftunnelling #tunn
