    Patent name: Method for absorbing shock wave elastic wave excitation residual signal to identify reflected wave signal

    Patent No.: ZL200910082851.4


    product description


    Artificial and automatic dual-mode analysis


    Creative anti-secondary excitation mode



    Unique Coupling Mode



    Sichuan Shengtuo Testing Technology Co., Ltd. provides anchor quality detectors. The equipment is mainly used for the quality inspection of slope tunnels, anchors and anchor cables of large-scale engineering projects such as roads, railways, water conservancy and ports. It can test the length of anchors/anchors and can also be qualitative for grouting compactness. test.

    In the test of anchor/anchor length and grouting density, the self-developed noise reduction technology and reflection signal extraction technology were also adopted, and the national invention patent was obtained.


    Test principle and method

    1. Detecting grout defects in the length of the anchor and the entire length based on the reflection characteristics of the impact elastic wave;

    2. Detecting the vicinity of the anchor head or the grouting defect of the short anchor rod based on the attenuation characteristic of the impact elastic wave;

    3. Detect the effective tension of the rock anchor based on the equivalent mass method (TTEM).


    Results and technical characteristics


    The effective tension of the rock anchor can be tested (equivalent mass method, TTEM);

    Can test the quality of rock anchor grouting;

    The accuracy and range of the rock anchor length test have been greatly improved.
