Intelligent detection method for grouting compactness of bridge prestressed pipeline

The invention discloses an intelligent detection method for the grouting compactness of a bridge prestressed pipeline, which belongs to the field of bridge construction. The method comprises the stepsthat the required grouting amount in a pipeline is calculated, flowmeters are installed at a grouting opening, an exhaust opening and a grout outlet of the prestressed pipeline, grout is pressed intothe pipeline through an intelligent grouting machine, the grouting compactness in the pipeline is calculated in real time, the compactness is monitored in real time through an intelligent means, andthe detection frequency and the percent of pass both reach 100%. The detection cost is saved by more than 95%, the detection time is saved by more than 90%, and the credibility problem which puzzles the pipeline grouting compactness detection result for a long time is solved; the problems of high difficulty in detecting the compactness of the prestressed pipeline, high cost and low detection frequency are solved; and the pr
