    Test items

    Test object: fabricated building

    Test item: sleeve grouting compactness

    Patent Name: Elastic Shock Wave Excitation Residual Signal Reduction and Reflection Signal Extraction Technology

    Patent No:ZL200910082851.4

    Related patents

    The basic principle of positioning test (modified shock echo equivalent wave velocity method: IEEV)

    The presence or absence of the grouting defect and the type of the grouting defect can be determined based on the presence or absence of the reflected signal at the position of the sleeve and the length of the reflection time of the underside of the building. When there is a defect in the pipe grout,

    Test principle and method

     

    Improved impact echo method IEEV test principle

    (1) The excited elastic wave will produce reflection at the defect;

    (2) The time when the excited elastic wave is reflected back from the opposite side of the beam is longer than the place where the grout is dense. Therefore, the equivalent wave speed appears to be slower.

     
     

    product description

    Sichuan Shengtuo Testing Technology Co., Ltd. is an expert in nondestructive testing technology, providing sleeve grouting quality detectors.

    In recent years, prefabricated buildings have continued to heat up in China, which has the advantages of saving energy, improving efficiency and improving production capacity. The connection and grouting of the sleeve part is a key part of the prefabricated building, which is naturally the focus of construction inspection.

    This instrument can carry out special inspection on the quality of sleeve grouting in prefabricated buildings. And the instrument has 2D contour rapid imaging, elastic wave radar scanning (EWR) and other post-image processing technology.
