    Patent Name: A Nondestructive Testing Method for Testing Tension of Prestressed Anchorage System


    Equivalent mass method

    When the buried anchor cable is excited by the anchor head, the induced vibration system is not fixed, but changes with the change of the anchoring force. The greater the anchoring force, the greater the quality of participation in free vibration.

    Test principle and method


    Accurate testing, test accuracy of more than 90%;

    The test range is wide, and the tension ranges from several tons to several hundred tons;

    The operation is simple and quick, the repeatability is good, and the influence factor is small;

    The main components are imported from the United States and Japan, with high reliability and durability.
