TBM: a revolutionary tool for underground tunnel construction

With the rapid development of urbanization, underground tunnels have become an important part of modern urban transportation construction. In underground tunnel construction, a revolutionary tool is leading the innovation of technology and efficiency, which is the TBM milling cutter.

TBM is a special excavation equipment that is widely used in underground tunnel construction. It consists of a large circular cutterhead and dozens or hundreds of blades, which rotate to cut underground rocks and soil to achieve underground tunnel excavation.

The application of TBM in underground tunnel construction brings multiple benefits. First of all, compared with the traditional blasting and excavation method, the excavation process of TBM milling cutter is safer and more stable, reducing the surface vibration and noise that may be caused by blasting, and protecting the surrounding buildings and environment. Secondly, the TBM milling cutter can achieve continuous operation, which greatly improves the efficiency of construction. Not only can underground tunnels be excavated quickly, but the support and lining of the inner wall can also be completed at the same time, reducing the construction period. In addition, TBM milling cutters can also effectively control the ground surface to avoid ground collapse and foundation settlement problems.

In addition to improving efficiency and safety, TBM cutters also reduce environmental impact during underground tunnel construction. Compared with traditional excavation methods, TBM milling cutters do not need to emit a large amount of smoke and tail gas generated by blasting, causing less environmental pollution and meeting the requirements of sustainable development. At the same time, because TBM milling cutters can keep the surface flat and reduce fluctuations in groundwater levels, they also play a positive role in protecting groundwater resources.
