摘要： A polymer composite grouting method for blocking leaking and sand inrush of underground pipeline includes steps of: (1) determining a leaking and sand inrush position of an underground pipeline; (2) drilling a plurality of grouting holes in a ground surface; (3) placing two grouting pipes into each of the grouting holes, binding a film bag at a bottom of one of the grouting pipes; (4) injecting a polymer grouting material via one of the grouting pipes to form a polymer sand stabilizing body; (5) extruding water to accumulated in the pipeline; (6) installing a plurality of geotextile bags at the pipeline section displacement; (7) injecting the polymer material into the geotextile bags for blocking the leakage; and (8) filling the pumping area out of the pipeline. The present invention provides a practical technical measure to treat the leaking and sand inrush of the underground pipeline under complicated geological condition.
