Function: It is primarily used to detect the completeness and integrity of foundation piles by utilizing the acoustic-transmission method. This means it assesses the quality and consistency of the concrete within the piles.
Standards: The instrument and testing procedures comply with standards like ASTM D6760 (Standard Test Method for Integrity Testing of Concrete Deep Foundations by Ultrasonic Cross hole Testing).
Features: Modern systems often include features like Wi-Fi connectivity for remote monitoring, specialized sensors for accurate data collection, high A/D resolution for waveform clarity, and user-friendly software for data analysis and report generation.
Function: Detects flaws like voids, honeycombing, cracks, and necking within concrete piles by analysing ultrasonic pulse propagation.
Method: Utilizes the Cross hole Sonic Logging (CSL) method, where ultrasonic waves are sent between probes in water-filled access tubes embedded in the concrete.
Standard Compliance: Meets or exceeds specifications of ASTM D6760, the Standard Test Method for Integrity Testing of Concrete Deep Foundations by Ultrasonic Cross hole Testing.
Target structures: Suitable for various deep foundation elements, including bored piles, drilled shafts, concrete piles, auger cast piles, diaphragm walls, and barrettes.
Advanced Features: Available in multi-channel configurations (2, 3, 4, channels) and supports advanced analysis features like 2D and 3D tomography.
Channels & Test Sections: It supports 2, 3, 4, channels and can be used with test sections 1, 3, 6..
Methodology: The system utilizes either the Iteration method or the Threshold method.
Probes & Connection: It uses 100m or 150m probe cables with a maximum spacing of 8m between probes, and offers both WIFI and cable connection options.
