tunnel inspection & assessment
Tunnel inspection and assessment is a vital process for safety and durability. It involves a thorough evaluation of structural integrity, component conditions, and operational systems. This proactive approach detects potential defects early, enabling timely maintenance, preventing major failures, and extending service life
Tunnel seismic prediction (TSP)
Tunnel Seismic Prediction enables an advance notice of geological uncertainties in the rock mass and is the key factor for efficient risk management.
Tunnel lining inspection
Integrate non-destructive testing technologies such as GPR and ultrasonic CT to achieve preventive maintenance throughout the tunnel life cycle
Tunnel section inspection
Tunnel lining deformation monitoring,segment ovality assessment & excavation control with millimeter accuracy
Tunnel seismic prediction (TSP)
Tunnel Seismic Prediction (TSP) is a geophysical method used to assess rock conditions ahead of a tunnel face during construction. It involves transmitting seismic waves into the rock and analyzing the reflected waves to map geological features and predict potential hazards. TSP helps in reducing risks associated with tunnel excavation by identifying faults, weak zones, karst formations, and water-bearing zones.

Tunnel lining inspection
Tunnel lining inspection involves assessing the condition of the tunnel’s structural support, including tunnel lining thickness, internal defects, etc., as well as identifying potential problems such as cracks, leaks or material degradation. This is critical to maintaining tunnel safety and preventing structural failures.

Tunnel section inspection
It is used for over-break and under-break detection of tunnel excavation sections, primary support and secondary lining sections, covering section measurement, surrounding rock convergence monitoring, earthwork volume calculation and blasthole indication. By adopting a comprehensive tunnel section inspection method, engineers can effectively manage the risks associated with tunnel operations and ensure the long-term reliability and safety of these critical infrastructures.
