1. Standard: ASTM D6760 Standard Test Method for Integrity Testing of Concrete Deep Foundations by Ultrasonic Crosshole Testing
2. Applications of Product
It is specially established to detect the completeness of foundation piles by means of acoustic-transmission method, which can also be employed in such functions as the detection of intensity via ultrasonic-rebound combined method, detection of lacunas and cavity, detection of facture depth via ultrasonic method and so on. A hoist of multi-channeled self-circulation can accomplish measurement of six sections in the concrete cast-in-place piles, which can greatly improve the efficiency of detection compared with single-section or one-transmission and two- receiving measurement instruments.
