Monitoring Tunnels

RFI – Exilles tunnel

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.
