A longitudinal connection structure of an assemblable sleeper slab-type or track slab-type ballastless track structure, a ballastless track structure comprising the longitudinal connection structure, and an assembly method for the ballastless track structures. Pre-embedded longitudinal steel bars (102) are longitudinally connected by means of an extrusion sleeve (104), mating ends of the two longitudinal steel bars (102) are respectively inserted into two ends of the extrusion sleeve (104), and under the extrusion of a portable extruder, the extrusion sleeve (104) is deformed and tightly locked. The longitudinal connection structure can improve the accuracy during on-site laying construction, facilitate disassembly and installation, reduce construction difficulties, and improve on-site construction speed; in addition, the longitudinal connection structure has a simple structure, and facilitates the positioning of a sleeper slab or a track slab.
