Abstract

The invention discloses a tenon anchor assembly type track unit and a tenon anchor assembly type track with the same. The track unit comprises a track plate set, an isolation layer and a base plate which is formed in a cast-in-place mode, has millimeter-level top surface smoothness control precision and is used for leveling the tenon anchor assembly type track unit, the track plate set, the isolation layer and the base plate are sequentially stacked from top to bottom in the height direction, and the track plate set, the isolation layer and the base plate extend in the train running direction. The tenon anchor assembly type track unit further comprises a connecting structure, the connecting structure and the track plate set can be formed in a one-time pouring mode or formed into a composite plate with a tenon in a two-time pouring mode, and the connecting structure is connected among the track plate set, the isolation layer and the base plate so as to be used for connecting the track plate set, the isolation layer and the base plate into a structure capable of being rapidly assembled. The tenon anchor assembly type track unit is simple in structure and convenient to construct, construction quality is easy to guarantee, maintenance and replacement are easy, environmental erosion can be effectively restrained, and the quality of the track structure can be kept for a long time.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a tenon-anchor assembled rail unit. Furthermore, the invention also relates to a tenon-and-mortise rail with a tenon-and-mortise rail unit. Background technique [0002] my country's high-speed rail technology has developed from scratch, from weak to strong, and has gone through four stages. After more than 20 years of continuous efforts, China has become the world's high-speed rail system with the most complete technology, the strongest innovation ability, the longest operating mileage, and the fastest operating speed. The fastest and largest country under construction. [0003] Ballastless track structure has become the main track structure type of high-speed railway due to its advantages of high smoothness, high stability, and less maintenance. The commonly used structure consists of track slab, filling layer, concrete base or support layer. At present, the main componen...
