Step 1 of 2

Tunnel convergence monitoring measures the deformation and stability of tunnel linings and surrounding rock mass during construction and operation. Underground infrastructure projects face unique challenges with ground movement, water infiltration, and structural convergence that can compromise safety and functionality. Our nationwide deployment covers tunnel boring machine operations, mined tunnels, and existing infrastructure assessments, providing tunnel owners with critical data for construction safety and long-term structural integrity.

Convergence monitoring uses precise displacement sensors, extensometers, and tilt meters to track tunnel lining movement in multiple directions. Automated data collection provides real-time views of tunnel stability, with threshold-based alerts for convergence rates that exceed design parameters. Integration with construction schedules ensures monitoring data supports safe tunneling operations and informs ground support decisions.

Our systems operate in challenging underground environments with high humidity, dust, and limited access. Wireless sensors and automated data transmission ensure continuous monitoring without disrupting construction activities. Data processing includes convergence rate calculations, trend analysis, and predictive modeling for ground behavior. Comprehensive reporting supports compliance with tunneling standards and provides documentation for regulatory approvals.
