Automated Tunnel Ribs
The primary lining generally involves the assembly and installation of tunnel ribs, which are steel arches designed to support the excavation as it progresses. The traditional procedure requires intensive manual work, and often these operations take place at very close distances from the excavation face.
Technological advancement has further improved risk control by the substitution of manual labour with automated solutions and ensuring zero personnel presence near the excavation face.
H-Beam Profile
The H-Beam automated tunnel rib represents the perfect combination of experience and technology, developed to increase safety and productivity. This innovative approach leverages the strength and stability of H-Beam structures, traditionally used in tunnelling, and combines it with automated installation processes. This automation significantly reduces construction time by 50% and minimizes labour risks.
Round Tubular Profile
The automated Round Tubular tunnel rib, with its innovative circular design and shotcrete filling, provides greater structural strength and reduces the amount of shotcrete spray needed during processing by 14%. This new approach represents a significant advancement in tunnel construction technology, streamlining the construction process, effectively minimizing material wastage and reducing environmental impact.
