A significant technological advancement in this process is the shift from manual labour to automation in the installation of tunnel ribs. This evolution not only streamlines the construction process but also enhances risk control. By substituting manual labour with automated solutions, there is no need for personnel presence near the excavation face, significantly improving safety conditions. This integration of advanced materials and automation represents a significant leap in tunnel construction, prioritizing both efficiency and worker safety.

The use of steel fibre-reinforced shotcrete during the primary lining phase marks a further advancement in tunnel construction technology. Our fibers, used to reinforce the shotcrete, ensure a uniformly distributed reinforcement, significantly enhancing the structural integrity of the lining. This method replaces the installation of welded mesh between the ribs, a process that poses considerable risks to the workforce involved. A revolutionary aspect is the use of the fibre-reinforced shotcrete to fill our automated Round Tubular tunnel rib. This setup creates a synergy between the steel of the rib and the concrete that provides a significantly enhanced mechanical performance.
