    Graphics processing function




    Sichuan Shengtuo Testing Technology Co., Ltd. provides a flawless track multi-function non-destructive tester (Type III), which can detect the structural quality of the high-speed railway ballastless track plate, mainly for the track plate and the adjustment layer (empty seam) , the base plate and the adjustment layer are emptied (separate from the seam), the wide and narrow joints and the adjustment layer are emptied (separate from the seam), the track plate and the base plate are cracked, the track plate and the base plate are damaged, and the width and narrow joint damage are detected. .

    The equipment system has rich graphics processing functions: elastic wave radar scanning EWR, computer tomography CT, fast planar imaging QPG, 3D slicing technology 3DS, fast planar imaging QPG, intelligent threshold calculation, and the area of the gap area and different states The gap condition is numerically represented, and the structural damage is evaluated by the defect and the residual modulus or strength.

    product description

    Results and technical characteristics


    For the structure of the track board, the wide-area signal pick-up device is specially customized to ensure the quality of the collected signal;

    The surface wave method is used to detect cracks, which are less affected by steel bars, moisture and crack faces;

    Based on the classical FFT spectrum analysis method, the MEM spectrum analysis method is introduced for more and more intelligent analysis methods.



    1. “Procedure for Nondestructive Testing of Railway Tunnel Lining Quality” (TB 10223-2004)

    2. "Quality Acceptance Standard for High-speed Railway Tunnel Construction" (TB 10753-2010)


    According to the standard

    Track plate void detection - impact echo method (IE 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.
