Application Summary AI generated
This standard specifies the technical requirements, dimensions, and testing methods for steel thin-walled sonic-testing tubes used in concrete bored piles. It is applied in civil engineering and foundation construction to ensure the tubes can reliably transmit ultrasonic waves for integrity testing of deep foundation piles. The standard governs the manufacturing and quality control of these tubes, which are embedded in piles during casting to enable non-destructive evaluation of concrete continuity and defects.
