The utility model discloses a novel high-grade vibration reduction ballastless track or a prefabricated assembly type track structure, which belongs to the technical field of ballastless tracks, and is characterized in that a lower foundation is constructed on the inner side wall surface of the bottom of a tunnel segment, and a reinforcing piece is arranged on the top surface of the lower foundation; the self-compacting concrete layer formed in a cast-in-place mode and the lower foundation can be poured into an integrated structure, then the limiting through hole of the track plate is arranged to be of a big-top and small-bottom structural form, the elastic buffering gasket is arranged in the limiting through hole, the vibration reduction layer is arranged on the bottom face of the track plate, and high-grade vibration reduction of the track plate after ballastless track construction can be achieved. According to the ballastless track structure, the construction procedure of the ballastless track in the tunne
