Competitive Advantages:
Non-contact evaluation, Instant measurement, Can be deployed on moving vehicle, Monitor large, extended installations.
In one embodiment, reinforced soil is assessed using a non-contact method including positioning a reference electrode in close proximity to a surface of the soil without contacting the electrode to the soil surface, vibrating the electrode with a vibration generator, and measuring an electrical potential difference between the electrode and the soil surface, the potential difference being indicative of the condition of a portion of a reinforcement member positioned below the soil surface at the location of the electrodeUSF researchers have invented a contactless Kelvin Probe to measure electric potential of the soil or soil filler surface. The probe can assess the corrosion condition of embedded metallic components such as soil reinforcement, and also serves to monitor cathodic protection in soils without disturbing the soil surface. This enables the probe to immediately measure potential without needing long stabilization periods experienced using conventional contacting reference electrodes. The technology has applications in monitoring the corrosion condition of buried metals, such as pipes and tunnels, and cathodic protection systems.
