🚀Let’s go! ✅ These two images illustrate crucial stages in tunnel construction and design, from both structural and detailed engineering perspectives. The first provides a cut section view showing how waterproofing, primary lining, and secondary lining are layered to resist both soil and water pressures. Proper sealing, joint design and drainage beneath the invert are taken into account to protect long-term durability and maintain serviceability. The second image is a technical drawing that com

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
