Embedded track system
The invention discloses an embedded track system. The embedded track system comprises a base, a prefabricated track plate and steel rails, and two rail support grooves whose bottom portions have gradients are arranged in parallel corresponding to the width of a train wheel pair on the prefabricated track plate; in the rail support grooves, elastic cushion plates are firstly continuously laid, then height adjusting backing plates whose bottom portions also having the same gradients as the bottom portions of the rail support grooves are arranged in a discretely mode, and then the steel rails are arranged in the grooves; prefabricated sections are adhered to the two sides of each steel rail, and wedge blocks are arranged between the prefabricated sections and the walls of the rail support grooves for adjusting transverse positions of the steel rails; high-molecular castables are cast in the rail support grooves for filling residual space; and an adjustment layer is formed through cast-in-situ concrete for combining the prefabricated track plate with the base. The embedded track system has the following advantages: the construction cycle of a track line is shortened, and the construction quality is effectively guaranteed; vibration and noise are low; and the service life of the track line is longer.
