Abstract

The invention discloses a thickening damping type high-speed railway II type track plate. The thickening damping type high-speed railway II type track plate comprises a base, wherein a track plate body is fixed to the top of the base, a gap is arranged between the base and the track plate body, and the void is filled with a cement asphalt mortar layer; a cavity is formed in the base, a steel plateis installed in the cavity, and inserting blades are fixed to the two ends of the steel plate; the inserting blades are fixedly connected in the base in an inserting mode, a plurality of locating columns are fixed to the steel plate, and the locating columns are fixedly connected to the bottom surface of the track plate body after penetrating through the cement asphalt mortar layer; first vertical through holes are formed in the two ends of the base and the track plate body; second through holes, corresponding to the first through holes, are formed in the inserting blades; and a fixing bolt is fixedly connected with the base after penetrating through the first through holes and the second through holes. The thickening damping type high-speed railway II type track plate can improve the deficiencies in the prior art, and improve the damping performance of the track plate.

Description

technical field [0001] The invention relates to the technical field of high-speed railway track slabs, in particular to a thickened and shock-absorbing type II high-speed railway track slab and a construction process thereof. Background technique [0002] The track slab is used to support the rails and evenly distributes the load generated by the train passing through the rails to the base. It plays an important role in the stability of train running. In 2016, the applicant applied for a utility model patent for a high-speed railway CRTS II track slab with an embedded PET network, which improved the bonding performance at the interface between the CRTS II track slab and CA mortar. However, the damping effect of the track slab is not significantly improved, and cannot meet the requirement of further improving the running stability of the train. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a thickened shock-ab...
