Wireless Tunnel Monitoring Remote Monitoring for tunnels, from construction to operation
Eddyfi Remote Monitoring Solutions brings together Senceive wireless monitoring and Sisgeo geotechnical instrumentation to monitor the behaviour of tunnels, surrounding ground and adjacent assets. Senceive wireless technology delivers precise, continuous data from compact, remote sensors, helping engineers understand movement and structural behaviour before, during and after tunnel construction, refurbishment and maintenance projects.
MONITOR TUNNEL BEHAVIOUR THROUGHOUT THE PROJECT LIFECYCLE
WIRELESS MONITORING FOR DEMANDING UNDERGROUND ENVIRONMENTS
Tunnel construction or repair works can lead to changes in the behaviour of the tunnel lining, the surrounding ground and infrastructure within the zone of influence. Continuous monitoring gives engineers the data needed to identify movement, understand trends and manage risk as work progresses. Senceive wireless monitoring can be deployed before, during and after construction, with sensors installed quickly and repositioned as the project develops. It can yield considerable cost savings compared to other methods, accelerate construction and help to manage risk.
Senceive sensors are compact, autonomous and suited to short or long-term deployment. A wide range of brackets and fixings allows sensors to be installed at any angle on concrete, steel, brickwork and other surfaces.
For sensors located deep within a tunnel, repeater nodes can relay data to a gateway positioned outside the portal. Wi-Fi or Ethernet can also be used where available.
Choose the communications platform to suit your project:
Monitor the parameters that matter • Tunnel convergence and divergence • Longitudinal settlement and heave • Structural deformation and rotation • Joint and crack displacement • Ground movement • Groundwater pressure • Strain and load • Temperature
Ideal for dense sensor networks where highly responsive reporting is required.
Suitable for widely dispersed sensors and locations where data needs to travel through physical obstructions such as soil and rock.

A FLEXIBLE APPROACH TO TUNNEL MONITORING
Triaxial Tilt Sensors
Compact, high-precision tilt sensors measure minute changes in angle or inclination, making them ideal for monitoring changes in tunnel geometry, structural deformation, settlement and heave. Their small size and flexible mounting options allow them to be installed directly onto tunnel linings and other structural surfaces.
Optical Displacement Sensor (ODS)
These can combine a laser and a tilt sensor to measure relative displacement between two points, making them particularly suited to monitoring tunnel convergence and divergence. Installed across the tunnel profile, they provide continuous measurement of changes in distance as excavation or construction progresses and throughout the operational life of the tunnel.
Wireless monitoring can be used across a wide range of tunnelling and underground applications, including:
• New tunnel construction • Refurbishment and structural modification • Track lowering and electrification • Monitoring third-party buildings and assets • Shafts and diaphragm walls • Temporary works • Structural health monitoring during operation
