Range finding greatly, does not the most destroy the advantages such as works, the most at home and abroad penetration and promotion, becomes most widely used concrete without broken
Damaging detection method, China carries out the research of this technology so far from the mid-50, no matter in terms of detection technique, instrument and equipment
All obtain major progress, make this technology each construction project wide popularization and application at home, improving construction quality, eliminating hidden
Suffer from, it is ensured that secure context has played great function, 1980, and first concrete ultrasonic detecting technology lists Ministry of Communications of China industry in
Standard " port engineering concrete test method " (is now renamed as " marine traffic engineering concrete test code ") after revision, arranges the most again
Enter Ministry of Water Resources and Power Industry's professional standard " concrete for hydraulic structure testing regulations " (SD 105-82)., nineteen ninety in 1988, China's Engineering Standardization
The committee's successively tissue is write, has been promulgated association's voluntary standard " Technical Specification for Testing Concrete Strength by Ultrasonic-rebound Combined Method "
(CECS 02:88) " ultrasound checking concrete defect technical regulation " (CECS 21:1990 is CECS 21 after existing revision
2000).After this, some are local and department has issued some relevant places and department's detection test procedure the most successively.These
The promulgation of code serves facilitation to popularization and the development of concrete ultrasound detection skill.
Concrete is a kind of heterogeneous body, porous, composition structure anisotropic composite material greatly complicated, dispersed, and
And xoncrete structure (such as dam, bridge) is bulky, structure is complicated, therefore, tradition machinery industry nondestructiving detecting means is the most aobvious
Obtain helpless, when ultrasonic wave is propagated in concrete, as met the internal flaws such as caking cavity, will be dissipated by these structures
Penetrate, produce the echo-signal of the acoustic characteristic information with internal structure of body, gather and process these echo-signals, can obtain
Internal structural information to concrete.
In the ultrasound detection to xoncrete structure, transducer plays an important role.Ultrasonic transducer is to realize acoustic energy
