According to the elastic wave theory, when the inner wall surface of the pipe joint is impacted by the impact vibration source, elastic waves are generated in the complex medium structure of the pipe joint, the annular space and surrounding soil, the distribution of the elastic wave fields of the inner wall surface of the pipe joint is determined by substances (air or water or slurry) in the outer annular space of the pipe joint, the surrounding soil of the pipe joint and the pipe joint materials, and therefore, the processing module can infer the properties (air, water, slurry or surrounding soil) of the substances in the outer annular space of the pipe joint by analyzing the elastic wave data, so that the slurry filling condition is obtained.
Specifically, the processing module 26 obtains the amplitude of the elastic wave, determines the material in the outer annular space of the pipe joint through the amplitude, determines that the air is in the outer annular space of the pipe joint when the amplitude is large, determines that the mud is in the outer annular space of the pipe joint when the amplitude is small, and determines that the water is in the outer annular space of the pipe joint when the amplitude is centered. An amplitude reference can be set, and if the amplitude reference is higher than the amplitude reference, the outside annular space of the pipe joint is indicated to be air, and the slurry at the outside annular space is not filled with the slurry and needs to be supplemented; the amplitude reference is lower than the amplitude reference, which indicates that the annular space outside the pipe joint is mud, and the mud is filled in the annular space; when the amplitude reference is equal, water is filled in the annular space outside the pipe joint, and slurry supplementing is also needed.
Further, when the data acquisition device 27 is provided, the processing module 26 is in communication connection with the data acquisition device 27, and is configured to receive the elastic wave stored by the data acquisition device 27.

The processing module 26 is further configured to receive the infrared image data generated by the data acquisition device 27, determine the slurry filling condition of the outside of the segment according to the reference temperature, combine the position information to obtain the slurry filling condition, compare the determination result of the infrared image data with the determination result of the elastic wave, and indicate that the accuracy of the slurry filling condition is higher when the determination result of the infrared image data is consistent with the determination result of the elastic wave. If the comparison result is inconsistent, outputting the two results for constructors to refer to.
