Abstract
A portable system for non-destructive evaluation of geological material structures comprises an impact device which impacts a spherical surfaced member against the surface of the structure. A vertical displacement transducer and a horizontal displacement transducer detect reflected signals from an interface of the structure, the signals being processed to give a indication of the depth of the interface from the surface of the interface and also provide an evaluation of the physical properties of the structure.
Claims6
A method for the non-destructive evaluation of deterioration of subsurface material structures occurring at an interface between the structure and the surrounding soil or rock, comprising:
- impacting a spherical surface on a surface of a structure;
- detecting reflected signals from said interface in said structure by a vertical displacement transducer;
- detecting reflected signals from said interface in said structure by a horizontal displacement transducer;
- and
- processing signals from said transducers to produce a measurement between said surface and said interface and a measurement of the physical properties of the structures.
