The invention discloses a longitudinal connection and wet connection type assembly method for a prefabricated sleeper plate or track plate type ballastless track. The longitudinal connection and wet connection type assembly method comprises the following steps: a lower foundation of the track is constructed; prefabricated sleeper plates are erected; longitudinal steel bars and split connection sleeves are adopted in an interval area for longitudinal connection and assembly, and fine adjustment and positioning are conducted; limiting components are constructed; a cast-in-place layer is constructed; reinforced concrete is cast in place at the two transverse ends of the interval area simultaneously provided with longitudinal connection structures and the limiting components to wrap and coverthe longitudinal connection structures and the limiting components, and connection filling parts are formed after solidification, so that the multiple prefabricated sleeper plates are assembled to form a track unit with the p
