Helical Acoustic Testing Pipe

Acoustic testing 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 grout at the pile bottom can significantly enhance their bearing capacity. Moreover, acoustic testing pipes can also be employed as conduits for cleaning and grouting treatment of accident piles, at which point measures must be taken to penetrate the pipeline at the defect areas requiring grouting.

Ultrasonic transmission method inspection, the overall requirements for the sound measuring tube are: joints must be secure and not come loose, sealed and not leak slurry; the tube wall should be smooth and not bent, even and without deformation; the tube body should be vertical and not tilted; and the interior should be clear of any foreign objects.

Poor material or installation of the sound wave pipe may lead to accidents such as leakage, pipe blockage, breakage, bending, sinking, and deformation, which significantly affect the ultrasonic pulse-echo method for pile foundation integrity testing, and may even render the method inapplicable.
