Monitoring Tunnels
RFI – Exilles tunnel
Background
Tunnels are an integral part of railway infrastructure. The mechanical deformation that can transpire over time in a tunnel represents a considerable risk to safety, during the tunnel construction phase and when it is operational. It is essential to always have up-to-date information on the stability and reliability of the structure.
The solution
A wireless Capetti Elettronica system consisting of a GSM control unit and dataloggers connected to potentiometer crackmeters was chosen to measure crack conditions in tunnel walls.
The result
A twofold benefit was achieved with this system:
- ongoing supervision of the relevant parameters during excavations and on completion of the tunnel;
- precise monitoring, thanks to a flexible, automatic data capture system, for optimal monitoring of the structural condition of the works, and prompt, accurate diagnosis of all events that could transpire.
