    Testing object: Effective prestress of single strand steel wire

    Detection Content: Effective Prestress under Anchor and Non-uniformity of Same Section

    Test items

    Patent name: a steel strand prestressing detection device based on reverse pulling method

    Related patents

    Patent No:ZL201620473075.6

     

    In the process of back-tension, the back-tension force and the displacement produced by the anchor cable are identified, and the back-tension force and displacement change are monitored to terminate the back-tension intelligently, and the recorded back-tension force and displacement are analyzed to find out the effective prestressing force of the anchor cable without destroying the existing condition of the anchor cable.

    Test principle and method

     
     
     
     
     
     
     
     
     
     

    High safety: the intelligent limit device can automatically identify the control balance point;
    The system automatically displays the value after balancing, automatically identifies the effective pre-stress value, without human intervention;
    Highly automated: the tension value stops immediately when it is balanced with the test value;
    High detection efficiency and protection of the original state of the structure, avoiding prestress loss caused by excessive tension;
    High accuracy: fundamentally avoid the error of artificially selecting the inflection point of the traditional force and displacement relationship curve;
    Database management service.

     
     
     

    Results and technical characteristics

     

    product description

     

    The anti-pull effective pre-stress detector uses advanced sensor technology and electromechanical technology. Through the intelligent limit device, the tension can be automatically controlled, the displacement of the clip can be controlled, and the balance point can be automatically recognized. When the tension value and the test force value are balanced, the oil pump can be stopped immediately, which is effectively avoided due to the over tension. The prestress loss greatly ensures the influence of the inspection on the quality of the project. The system is simple in operation, high in precision and high in reliability. It is a revolutionary technology for reverse tensile prestress detection.
