Geotechnical and tunneling solutions are designed to ensure stability and safety in challenging underground environments. Covering a wide range of applications including excavation support, slope stabilization, rock reinforcement and monitoring, these systems enable efficient and reliable operations. By combining proven support technologies with advanced monitoring and control, they help manage ground conditions, reduce risks and optimize performance throughout the entire project lifecycle.

Rock bolts provide reliable ground support by reinforcing the rock around the tunnel profile. Together with shotcrete and other primary support measures, they create a strong, stable system that enhances safety and supports long-term tunnel stability.
Passive support solutions provide reliable tunnel stability by allowing controlled interaction with the surrounding ground. Steel thread bars, lattice girders, and other elements work together to manage loads, accommodate deformation, and ensure safe, resilient tunnel construction in challenging geological conditions.
The 20mm, 25mm and 32mm left-hand threaded bars of Yidao are widely used in these two fields.
