Tunnel Profile Monitoring System

Tunnel Profile Monitoring System

The system involves a series of linked rods, fixed to a tunnel wall to monitor deformation.
A datalogging system and related software is available to provide near real time displacement and generate a graphical representation of tunnel performance.

For monitoring:

-Underground openings during construction for control and safety
-Tunnel deformation due to nearby construction
-Long-term deformation and performance of existing tunnels


-Low profile design with multiple arms to fit close to tunnel wall
-Does not interfere with tunnel traffic
-High system accuracy of up to 0.02mm of deformation
-Custom engineered to suit each individual application
-Immune to air density problems inherent in optical systems
-Direct measurement of displacement rather than calculation from tilt measurement
