The invention discloses a longitudinally-connected ballastless track and a mounting method thereof, and belongs to the technical field of track traffic. The longitudinally-connected ballastless track comprises a base plate and a plurality of track plate assemblies; the base plate is of a long-strip-shaped structure; each track plate assembly comprises a track plate and four fixing pieces, the plurality of track plates are arranged at intervals in the extending direction of the base plate, and for any track plate assembly, the track plate is laid on the base plate; and the four fixing pieces are arranged at the four right angles of the track plate respectively, each fixing piece comprises two side plates arranged in an L shape, the two side plates are perpendicular to the base plate, the two side plates are detachably connected with the base plate, and the two side plates make contact with the two adjacent side edges of the track plates respectively so as to clamp the track plates. According to the longitudinally-connected ballastless track provided by the invention, the influence of temperature force on the track plates is effectively avoided, the stability of the track plates in the transverse direction and the longitudinal direction can be guaranteed, and accurate positioning of the track plates is achieved.
Description
technical field [0001] The invention belongs to the technical field of rail transit, and more specifically relates to a longitudinally connected ballastless track and an installation method. Background technique [0002] Ballastless track is widely used in high-speed railways. Compared with traditional ballasted track, it has the characteristics of high laying accuracy, good ride comfort and less maintenance. [0003] Since the longitudinal ballastless track is laid continuously in the longitudinal direction, the temperature effect is very significant. In the high temperature season, the huge temperature force accumulated inside the track slab cannot be released, and vertical arching and material collapse are prone to occur at the longitudinal weak point of the track slab. In severe cases, it will affect Driving safety. In related technologies, in order to release excessive temperature force, the longitudinal ballastless track can be unitized (that is, multiple track slabs ...
