Acoustic wave pipes, in addition to serving as detection channels and replacing part of the steel reinforcement cross-section, can also be used as pipes for grouting at the pile bottom. Tests have proven that piles treated with grouting at the pile bottom can significantly enhance their bearing capacity. Moreover, acoustic wave pipes can also be used as pipes for cleaning and grouting treatment of accident pile defects. In this case, measures must be taken to penetrate the pipes at the grouting defect locations.

Ultrasonic transmission method testing requires the following for the overall sound testing tube: firm joints that do not come loose, sealed without leakage; smooth, undamaged tube walls; straight, without deformation; vertical tube body without tilting; and clear interior without foreign objects.

Poor material or installation of the sonic logging pipe may result in accidents such as leakage, pipe blockage, breakage, bending, sinking, and deformation, which significantly impact the integrity testing of pile foundations using the ultrasonic pulse-echo method, and may even render the method inapplicable.
