    Cross hole rock mass mechanical property detector

    Device name
    Cross hole rock mass mechanical property

    Testing distance is long, up to 50m


    Anhydrous Coupling Technology for Horizontal, Upper and Fissured Boreholes



    Sichuan Shengtuo Testing Technology Co., Ltd. provides a cross-hole rock mass mechanical property detector. The instrument is mainly used for the testing of large-volume concrete, internal mechanical properties, defects, joints, etc. of rock mass. The test uses waterless excitation and coupling technology, and can be applied to various directions such as oblique holes and upward direction holes. As long as it is a dry hole with a hole diameter between 90mm and 110mm, it can be tested. The maximum test pitch is up to 50m. At the same time, it has rich post-processing functions such as elastic wave radar EWR, computer tomography CT, 3D slicing technology and automatic fast processing skills, which can bring the most simple and intuitive test results.



    product description


    When testing large-volume concrete structures, the cross-hole device can be

    used to test the concrete structural characteristics and defects between the

    drilling holes. The cross-hole device uses waterless coupling and excitation

    technology, which is suitable for drilling in various directions. The distance is

    up to 50m), and the automatic vibration excitation device and the cylinder

    pressure sensor are used for fixing, and the directivity is strong and the

    attenuation is small.



    Test principle and method


    Test items

    Test object: large concrete structure, natural rock structure, etc.

    Test content: Mass concrete of tunnels, dams, etc., internal mechanical properties, defects, joints of rock mass


    Results and technical characteristics

    Waterless coupling, can be applied to drilling in any direction, especially suitable for the detection of rock loose area around the tunnel and forward forecasting;

    The detection distance is long, and the detection distance in concrete can reach 50 meters;

    No need for high voltage power supply;

    The image is rich in functions and can be CT imaged.
