Full Face Tunneling Boring Machine in Rock Condition

Full face rock tunneling machine (TBM) is a large-scale underground construction equipment that integrates mechanical, electrical, and hydraulic systems with high technological intensity. It is mainly used for the construction of railways, highways, water conservancy and hydro power tunnels, subways and underground engineering tunnels in rock layer. According to different rock conditions, tunneling machines can adopt shield or open structures, with support methods such as anchor rods, anchor cables, mesh laying, arch beams, shield tunnel segments, grouting, and concrete spraying, achieved the requirements of detecting before tunnel boring and test boring in advance. The tunnel boring system includes boring, support, ventilation and dust removal, long-distance material and soil transportation, self-navigation and intelligent monitoring for parallel continuous operations. Achieved safe, efficient, high-quality, economic development, less labor, and intelligent tunnel boring aim.

The full face rock tunneling machine is suitable for tunnels with a diameter of 3.8m-5.0m, a slope of about 10%, a tunnel length longer than 3000m, and an uniaxial compressive strength of rock ≤ 250Mpa.
