The invention discloses a wet-connection type assembling method used for a prefabricated sleeper slab type or prefabricated track slab type ballastless track in a vibration absorbing section. The wet-connection type assembling method used for the prefabricated sleeper slab type or prefabricated track slab type ballastless track in the vibration absorbing section comprises the steps of constructinga track lower foundation; constructing a vibration absorbing layer on the track lower foundation; longitudinally arranging and erecting prefabricated sleeper slabs or prefabricated track slabs on thevibration absorbing layer along a line in a spaced manner; arranging longitudinal connecting pieces and limiting reinforcements; placing limiting sleeves outside the limiting reinforcements in a sleeving manner; pouring cast-in-place layers on the track lower foundation and the prefabricated sleeper slabs or the prefabricated track slabs; correspondingly pouring reinforced concrete to the two transverse ends of a spacer region in which the longitudinal connecting pieces and limiting members are simultaneously arranged; covering the longitudinal connecting pieces, the limiting reinforcements and the limiting sleeves in a coating manner; and after curing, forming a connecting filling part. According to the wet-connection type assembling method used for the prefabricated sleeper slab type orprefabricated track slab type ballastless track in the vibration absorbing section, rapid, adaptive and efficient assembling is realized through assembling connection; and meanwhile, the structural function is improved while the process of the limiting and connecting procedure is reduced.
