Zusammenfassung:Discloses is a mosaic type lead-over groove which is characterized in that the mosaic type lead-over groove comprises a lead-over bottom groove and a moving upper flange slab; wherein the lead-over groove and the moving upper flange slab adopt a tire bead push-pull structure which is integrated with a bolt structure by a dowel pin and a pin. As the lead-over groove and the moving upper flange slab adopt the tire bead push-pull structure which is integrated with the bolt structure by the dowel pin and the pin, when the abrasion of the moving upper flange slab exceeds the limit, only the moving upper flange slab needs replacing without replacing the whole lead-over groove, so the lead-over groove has the advantages of time saving, labor saving and convenience.
