Abrasion-resistant repair grouting material for ballastless track filling layer gap and repair method

The invention discloses an abrasion-resistant and corrosion-resistant repairing grouting material and a repairing method for a ballastless track filling layer gap, and the repairing method comprises the following steps: determining a to-be-repaired position and a to-be-repaired range according to the structural stress and deformation characteristics of a ballastless track, and calculating the use amount of the required grouting material; drilling and dedusting are conducted on the track plate corresponding to the to-be-repaired range; grouting materials are quantitatively injected into the corresponding positions in the filling layer in a targeted mode through a grouting pipe according to the preset grouting speed and the grouting rhythm of grouting-stopping-grouting; and when pause is carried out according to the grouting rhythm, high-pressure air is blown into and sucked out of the filling layer according to the preset rhythm at the preset pressure, the preset direction and the preset air speed along the ga
