    Results and technical characteristics

     

    Equivalent mass method (TTEM): testing the tension of a buried anchor/rod;

    Full-length attenuation method (FLEA): Qualitative test of the porosity of the prestressed beam;

    Equivalent Wave Velocity Method (IEEV): Positioning and type discrimination of grouting defects of prestressed beams;

    Transfer Function Method (PFTF): Characterizes the grouting defects in the vicinity of the anchor head of the prestressed beam. According to this, not only can the effective tension of various anchor cables/rods be tested, the grouting compactness of the prestressed beams can be quickly qualitatively detected, accurately positioned and typed, and at the same time, the concrete material (structure, test piece), beam thickness It can also be tested.

    Sichuan Shengtuo Testing Technology Co., Ltd. provides a channel grouting compactness quality detector.
    The device is mainly used for the grouting compactness detection of prestressed bridge cables. The full-length wave velocity method (FLPV) and the full-length attenuation method (FLEA) can be used to quickly and qualitatively detect the pipe compactness; the impact echo equivalent wave velocity method (IEEV) can be used to locate the grouting defects. FLEA and IEEV have applied for invention patents.

    Positioning test and defect type

    Tested continuously (excited and trusted) in the form of a scan along the upper or side of the pipe, and the condition of the grout in the pipe is tested by the characteristics of the reflected signal.

    Test principle and method

    Qualitative test

    The method can quickly detect the tightness of the grouting of the tunnel, and test the steel strands exposed at both ends of the anchor cable.
    In one test, the above three methods (FLEA, FLPV, PFTF) can be tested simultaneously, and the test time for completing one channel is within 5 minutes.
