Services
Tunnel Boring Machine Excavation
Our TBM tunneling services combine advanced machinery with precision engineering to create efficient underground passages. We execute projects with minimal surface disruption while maintaining strict safety protocols. This method supports large-diameter tunnels for transportation and utility infrastructure across diverse geological conditions.
Sequential Excavation Method Tunneling
We employ sequential excavation methods for complex ground conditions where mechanized tunneling isn't feasible. This adaptive approach allows controlled excavation with real-time ground support systems. Our engineers optimize construction sequences to ensure stability in challenging urban and geological environments.
Shaft Excavation
Our shaft excavation services create critical access points for underground infrastructure using advanced earth retention systems. We implement tailored solutions for deep excavations in urban environments, maintaining structural integrity while minimizing vibration and ground movement impacts on surrounding areas.
Ground Reinforcement
We provide comprehensive ground improvement solutions using techniques like jet grouting, ground freezing, and dewatering systems. These methods enhance soil stability for construction in challenging conditions. Our engineers design customized reinforcement plans to ensure safe and durable underground structures.
Tunnel Rehabilitation
Our rehabilitation services extend tunnel lifespans through structural repairs, waterproofing systems, and performance enhancements. We assess existing infrastructure to implement targeted upgrades that improve safety and functionality. This includes comprehensive assessments and implementation of modern maintenance solutions.
