Grouting water gushing treatment method

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
