Operation high-speed rail ballastless track supporting layer pulverization disease treatment method

The invention discloses an operation high-speed rail ballastless track supporting layer pulverization disease treatment method. The method comprises the steps that a pulverization section supporting layer is divided into a plurality of small units according to the sleeper spacing in the line direction; the exposed concrete pulverization surface layer of each small unit supporting layer is polished by a certain thickness, and the polished supporting layer meets the rebound strength; cutting or chiseling away the pulverized supporting layer within a certain range of the lower outer side covered by the roadbed slab or the track slab until the pulverized supporting layer is flush with the surface of the polished supporting layer on the exposed surface, and cutting the outer side of the roadbed slab into a chamfer; coating an anti-stripping agent on the surface of the support layer after cutting, chiseling and polishing, erecting a formwork on the outer side of the support layer, and pouring an early strength ceme
