Prefabricated floating slab track with adjustable vibration reduction level

The invention discloses a prefabricated floating slab track with adjustable vibration reduction level. The track comprises shield segments, a substrate, an adjusting layer, prefabricated track platesand an isolation layer for vibration reduction, wherein the substrate is arranged at bottoms of the shield segments, and the adjusting layer is arranged on the substrate; the prefabricated track plates are arranged in the adjusting layer and flush with the top of the adjusting layer; the isolation layers are arranged in contact positions of the prefabricated track plates and the adjusting layer. The track has the beneficial effects that the prefabricated track plates are completely isolated from leveling layers of self-compacting reinforced concrete, and can be quickly lifted, the isolation layers are changed from existing geotextile into vibration reduction pads, and the vibration reduction level of the track is improved, so that the track has significant social and economic benefits; bypre-burying drain pipes, t
