A method for detection of defects in concrete structural elements

摘要

A method for detection of defects in components, in particular of errors in clamping channels or compaction deficiencies in concrete structural elements, with the following steps:Means of irradiation with pulsed ultrasonic waves from electrical transmission pulses at a plurality of locations of the surface of the structural member to be tested,Receiving the reflected ultrasonic waves at a plurality of locations of the surface for the production of a plurality of electrical received signals,Evaluating the electrical received signals using the positions of the points of the incident ultrasonic waves, and of the received reflected sound waves to the production of a three-dimensional spatial distribution of the scattering properties of the component and analyzing the three-dimensional spatial distribution of the scattering properties with respect to the amplitude information,characterized by the,that in addition to the amplitude information of the three-dimensional spatial distribution of the scattering properties of the component, the phase information is analysed, whereby the defects due to the analysis of the amplitude information and the phase information of the three-dimensional location distributor detected and the scattering properties are determined.
