    Why is the anchor length test preferred for automatic identification, and artificial identification as a supplement?

    Automatic identification and manual recognition are two methods for identifying reflected signals at the same time. In the application is a complementary relationship, in general, the test results can be mutually corrected. The details are as follows:
     
    Automatic recognition of reflected signals, the device integrates correlation analysis and other methods, automatic analysis of human factors is small, analysis is simple and fast. On the one hand, the device adopts scientific preset length interval, half-wave movement, amplification processing and other techniques to enhance the automatic recognition ability of the bottom end of the column. On the other hand, manual identification can be used to assist analysis when necessary, thus greatly improving the test. The scientific and objective nature of the results.
     
    Manual identification can be used as an auxiliary method for bolt length testing, but it cannot be used as a primary analytical tool. The anchor rod is a solid rod, and the reflection point is theoretically well recognized, and generally has a large spacing from the initial signal. In fact, depending on the degree of grouting of the anchor and the degree of energy attenuation, the reflected signals are indistinguishable, and a large number of interfering signals are generated in the uncompacted position of the anchor grouting. It is difficult to identify the accurate reflection by the test waveform alone. signal. As shown in the figure below, the artificial signal is very recognizable.
     
    When the bottom reflection signal is indistinguishable from other reflection signals, even if the short rod initial signal and the reflection signal are superimposed on each other, the artificial identification will be helpless. If the artificial identification is forcibly used, the scientificity and objectivity will no longer exist.
