Cross Hole Sonic Logging Equipment
All-in One system MCHA Cross-Hole Tester is an Ultrasonic Cross-Hole testing kit , also referred to Ultrasonic Crosshole Sonic Logging system . MCHA is used for a common test for concrete foundations , where tubes are cast into the concrete during construction so that a series of tests can be carried out between pairs of tubes. The transmitter and receiver Probes are lowered and transit time and energy is measured for high resolution , accurate and reliable assessment for integrity of deep foundation elements.
Uniform and good quality concrete will allow propagation of ultrasonic waves. Should the ultrasonic wave travel time be longer and energy measured be of a lower amplitude correspond to poor quality or concrete or concrete with voids. A complete loss in signal means a substantial void is hindering the transfer of the signal between the hydrophones.
The All-in-One MCHA is accordingly utilised for Quality Assurance testing of newly constructed critical drilled shaft foundations , auger cast piles and slurry walls. Ultrasonic cross-hole testing is designed for checking posts and diaphragm, cavities / faults and seepages detection. The CSL test procedure using MCHA All-In-One ultrasonic crosshole testing kit can detect anomalies inside concrete within just minutes. All-in-One MCHA s a rugged and reliable equipment with various dedicated piezoelectric sensors and probe that is characterized by an A/D board multichannel and selectable sampling rates from 1OOHz – 10 MHz. All acquired signals are displayed, computed and memorized directly on tablet pre-installed MCH-sonic software. Connection between All-in One system and tablet is via WiFi.
