Background
The anchor rod nondestructive testing is mainly used for testing the rod body length and the grouting compactness of an anchoring section of the anchor rod after construction, and the basic principle is a sound wave reflection method. The method is characterized in that a sound wave signal is excited at the head of the anchor rod, the signal is transmitted to the bottom of the anchor rod along the rod body of the anchor rod, the signal is reflected when meeting the position where the wave impedance changes obviously (such as the rod bottom, grouting defects and the like) in the process, the reflected signal is picked up through a sensor arranged at the top of the anchor rod, the signal is transmitted to a signal acquisition instrument through a cable to be received, the actually measured signal is analyzed according to the fluctuation theory, and finally the length of the anchor rod and the anchoring quality are evaluated.
Theoretically speaking, the method can accurately detect and judge the length of the anchor rod body and the grouting compactness of the anchoring section through a sound wave reflection method. The theoretical technology is mature, but the actual application effect is difficult to achieve expectation due to the fact that an actually measured effective signal is weak in the detection process and is influenced by vibration excitation effect of a vibration source, environmental factors, acquisition quality of a signal acquisition system and other factors. With the rapid development of the industries of electronics, crystals, computers and the like in recent years, the anchor rod nondestructive detector is also advanced by more advanced hardware acquisition systems and sensors, and the signal acquisition quality is improved. However, the problem remained in the past, that is, the excitation mode of the elastic wave has many defects, is not solved from the source of the signal.

However, the excitation mode has high requirements on the technology and experience of testers, and when different testers adopt the same equipment for detection, the quality of knocking signals is different, so that the tested results may be completely different. Meanwhile, the same anchor rod is easy to be interfered by human factors during knocking, so that the consistency of multiple tests of the same anchor rod is poor, and the result is difficult to judge.
The ultra-magnetic vibration source utilizes the characteristics of magnetostrictive materials, provides a stable excitation force through peripheral equipment, and can be used for holding the vibration source at the top of the anchor rod by hands during excitation, so that the test mode effectively reduces the interference of human factors in the excitation process, ensures the consistency of test signals and improves the test efficiency. But the excitation frequency and the energy are fixed, the whole adaptability is not strong, and the excitation frequency and the energy are difficult to adapt to various different anchor rods.
The application number is CN 200920087483.8's chinese utility model discloses a portable super magnetostrictive vibration source device is exclusively used in 2010, 07 month 21 days, including the impact output pole, the guide protects the head, pre-compaction stress adjusting plate, super magnetostrictive rod, the drive coil, the impact control circuit, power module, the impact control circuit links to each other with drive coil and power module, the impact control circuit with power module dress in the shell, the impact output pole protects the head with the guide in proper order, and a housing, the back lid is connected, it is fixed that the impact output pole protects the head through the guide, the guide protects the head for the toper round platform structure, the one end at the shell is connected to the bottom surface that the guide protected the head, super magnetostrictive rod passes through the screw mouth with the impact output pole and is connected. The impact control circuit is arranged in the middle of the cavity and connected with the driving coil and the power supply module.
