Installation:Ingenieria de Instrumentacion y Control S.A.
Two hydraulic tunnels of 720 m of length that are part of an hydro power plant in Cartagena (South Spain).
Aims of monitoring:
Monitoring of two hydraulic tunnels during excavation in area with important geotechnical problems. Aim of the instrumentation is to detect any cracking in the second concrete layer of the tube and monitor tunnel deformations during power plant service (when water is flowing through the tunnels).
Number of sensors:33
Measurments with SOFO system allowed concrete cracking evaluation in the second layer of the tube and guaranteed good execution of tunnels excavation. Long term deformation monitoring of the tunnels guarantees the safety and correct operation of the hydro power plant.
