BRIDGES AND OVERPASS


Sibyl monitors the structural integrity of bridges and highway overpass.

Structural monitoring usually involves the measurement and control of static deck inclinationsdeflection measurements of bridge beams, and dynamic modal parameters.

The Numbers

  • 74 sensors
    • Thermometers
    • Inclinometers
    • Accelerometers
    • Strain sensors
  • 3700 data acquired per second
  • Sampling frequency: 50 Hertz
  • System installation time: 5 days
  • Monitoring: 24/24h- 365d/year

HIGHWAYS' FAN


Sibyl monitors fans installed on highway’s tunnels.

The monitoring usually involve the measurement and control of static deformations (inclinations, axial deviation) of fan brackets, as well as the temperature and vibrational state of each fan.

The Numbers

  • 28 fans
  • 9 sensors per fan
    • Thermometers
    • Accelerometers
    • Strain sensors
  • 5 km of optical fiber
  • Sampling frequency: 1000 Hertz
  • Monitoring: 24/24h - 365d/year

TUNNELS


Sibyl real-time checks sensors on assets like tunnels and roads, monitoring, for example, the convergence and longitudinal deformations of tunnels, and the overall status of the infrastructure.

The Numbers

  • 80 sensors - 30 km optic fiber
  • 7800 data acquired per second - 4 PLE
  • System installation time: 18 days
  • Monitoring: 365 d/year

CONSTRUCTION SITES


Sibyl platform is used to monitor the structural integrity of buildings in proximity to the demolition, excavation and construction of new buildings.

Structural monitoring involves measuring static deformations (inclinations, deflections, lengthening, shortening) and dynamic stresses (accelerations) on pre-existing structures and on bulkhead poles along the perimeter of the excavation.

The Numbers

  • 50 sensors
    • Thermometers
    • Inclinometers
    • Accelerometers
    • Strain sensors
  • 1 km of optical fiber 50 Hertz per sensor
  • System installation time: 2 days

SEWERS


Monitoring underground tunnels and pipes, involves data acquisition of Brillouin distributed sensors installed in the sewer pipes of cities.

Sibyl measures vertical and horizontal pipeline deformations, the level, speed and flow rate of the sewage and controls anomalies due to parasitic infiltrations from outside the pipeline. All data is indexed and dashboards are created to facilitate interpretation.

The Numbers

  • 2 Brillouin loops
  • 37 Km of Brillouin distributed fiber 
  • Monitoring: 24/24h - 365d/year
