    Ballastless track void detector (type III)

    Device name

    Test items


    Test object: CRTS-III track plate

    Test project: track plate void

    Track plate void detection - IE plane imaging method

    The track plate void detection uses the impact echo method (IE method), and its acquisition schematic is as above. The elastic wave signal is continuously excited along the surface of the track plate, and the signal will be reflected when it encounters a loose medium such as a void or a cavity. By extracting the abnormal reflection signal and performing corresponding processing, the position and depth of the void can be identified.

    Test principle and method


    Results and technical characteristics

    Powerful, easy to test: Quickly detect the void of the track board (CRTSIII type), the instrument operation is simple, and with the cooperation of the remote control pen, one person can also complete the test;

    Advanced technology: with impact elastic wave and vibration as test media, special customized components for track plate structure (wide-area signal pick-up device) combined with the company's self-developed concrete testing technology, with the characteristics of strong test and high precision;


    Structural quality inspection
