FIELD: civil engineering, nondestructive testing of building reinforced concrete structures. SUBSTANCE: technique controlling positions of fittings in reinforced concrete structure consists in placement of transducers on concrete surface of structure, determination of coordinates of positions of fittings in body of concrete. Location group of transducers of acoustic emission is placed on surface of structure, surface layer of concrete is broken locally, sources of acoustic emission are recorded and their volume coordinates are established and used to make judgment on positions of fittings in structure. EFFECT: reduced labor input to process of determination of coordinates of positions of fitting in body of concrete, increased measurement accuracy. 3 dwg |
