Defend tunnel safety
The supporting structure is closely combined with surrounding rock to build a stable tunnel structure system, resist various external challenges and protect tunnel safety.
Keep the space in the tunnel intact.
The supporting structure maintains the integrity of the inner space of the tunnel, which makes the driving and walking smoother and improves the tunnel traffic efficiency.
Prevent the quality of surrounding rock from declining.
The supporting structure provides solid support and protection for the tunnel, prevents the quality of surrounding rock from declining and ensures safety.
Harmonious life
The supporting structure must be closely combined with the surrounding rock to form a solid whole and be able to resist external forces. At the same time, the tunnel structure is allowed to deform moderately within a certain range to achieve harmonious life.
Staged construction
The supporting structure supports the construction in stages, ensuring the perfect cooperation between the early support and the later support, actively adjusting the stability of surrounding rock and improving the construction efficiency.
