The invention discloses a grouting water gushing treatment method. The grouting water gushing treatment method is characterized by comprising the following steps that the water gushing pressure P0 andthe water gushing flow Q0 are measured, and whether or not water gushing occurs is judged; if water gushing occurs, the grouting pressure P is increased, and whether or not the water gushing flow Q0and the permittivity q are greater than a preset value a is judged; if the gushing flow Q0 and the permittivity q are smaller than a, grouting is conducted according to a normal grouting-beginning water-cement ratio; if the gushing flow Q0 and the permittivity q are greater than or equal to than a, the grouting-beginning water-cement ratio is adjusted to 1:1, and whether or not the injection rateis greater than a preset value b is judged; when the injection rate is greater than a preset value b, whether pressure rise and injection rate reduction are obvious within a preset time; if not, the grouting ratio is skipped to 0.5:1 till the grout closing condition is met; and after the grout closing condition is met, the water-cement ratio of grout is adjusted to 1:1 for grout closing if the water-cement ratio of the grout is greater than 1:1, and then grouting is ended. According to the grouting water gushing treatment method, water gushing is judged by measuring the water gushing flow, thewater gushing pressure and the permittivity, and the problem of water gushing is solved by adjusting the water-cement ratio of the grout and by carrying out grout closing.
