Method for rapidly repairing cement emulsified asphalt mortar interface connection damage of unit slab ballastless track
The invention relates to a method for rapidly repairing cement emulsified asphalt mortar interface connection damage of a unit slab ballastless track; the method mainly comprises the steps of cleaning, sealing, setting of grouting openings, interface connection damage grouting and edging treatment; the specific steps are as follows: firstly, cleaning dust and impurities around a mortar interface connection damage; secondly sealing the interface connection damage area, setting the grouting openings and placing a dial indicator at four corners of a track slab in a to-be-repaired area; thirdly, connecting a dual-component self-mixing grouting machine with a pressure grouting hose, and injecting a dual-component grouting material to the grouting openings in sequence; after the mortar comes out of a grouting opening having the spacing of more than the width of the track slab with the next grouting openings, turning to the next grouting opening to grout continuously till the whole cement emulsified asphalt mortar seam area is fully grouted; and finally, cutting the grouting hose, polishing sealed materials to finish the repairing. The method has the characteristics of simple and rapid process, high repairing efficiency and capability of realizing rapid repairing within skylight time and is applicable to repairing the cement emulsified asphalt mortar seams of the unit slab ballastless track.
