Embodiment Construction
[0027] Such as figure 1 As shown, the present invention provides an intelligent detection and quantitative identification method for concrete defects, including the following steps:
[0028] a) Signal sample collection; collection of shock echo signals of a series of concrete model specimens, which include various types of quality defects and normal quality specimens;
[0029] According to the common quality defects of concrete structures in actual projects, and the basic requirements of the current concrete test procedures, a series of defects of different types and properties, such as cavities, cracks, and non-dense entities, are produced according to the common mix ratio, molding process and reinforcement design And the concrete model specimens of normal quality, and the impact echo method is used to test these model specimens. The testing equipment adopts the Impact-E impact echo tester of the American Impact-Echo company; through model experiments, we will study this in depth. ...
