Monitoring challenges
Cost maintenance
Huge structures are very costly to monitor with cabled installations: wireless sensors are the optimal solution.
Soil stability
During the construction and the life of the tunnels it is important to understand the soil type and the deformation state.
Static monitoring
Control terrain deformation, tensions, stresses, and subsidence.
Structural deterioration
It’s necessary to analyze the degradation of the structure and of the ground over time.
KEY PARAMETERS FOR TUNNEL MONITORING
Using a series of Tiltmeters or Tilt-beams, positioned in series on a section of the tunnel, it is possible to obtain convergence measurements of the coating and to establish if and how it is deforming.
With the use of the Analog and Digital communication nodes, it was possible to expand this monitoring system to other non-native wireless instruments of geotechnical type, such as load cells, crackmeters, vibrating wire and more.
Soil stability
You can evaluate both the pressures exerted by the ground, the load distribution on the foundations and its deformation.
Geotechnical parameters
You can monitor the ground displacement (settlement or lateral movement) and groundwater levels.
Tilt variation
You can measure the Pitch angle and the Roll angle with high precision. These measurements allow obtaining fundamental parameters for the static monitoring of the tracks.
Environmental monitoring
Control of all external atmospheric agents such as wind direction and speed, rain, humidity and temperature.
