Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to Fig.1, a kind of ballastless track structure for heavy grade rack rails traffic system of the utility model, including under
Base plate 10, filled layer 30 and the track plates 20 set gradually on and, 20 plate face both lateral sides of track plates are set with longitudinal gap
The track 21 set, rail are fixed on track 21 by fastener system, and rack rails is fixedly mounted in the longitudinal direction of track plates 20
On line.Using the non-fragment orbit being made of base plate 10, filled layer 30 and track plates 20, Ballast track is eliminated in heavy grade area
Section, big-inclination the curve section security risk dynamic there may be railway ballast sliding.20 bottom interval of the track plates setting limit
Structure, position limiting structure are passed down through filled layer 30 and enter in base plate 10, prevent track plates 20 from misplacing with base plate 10.
Referring to Figure 1 and Figure 3, the position limiting structure is arranged in heavy grade section along the longitudinal gap of track plates 20.Referring to Fig. 6
And Fig. 7, the position limiting structure being horizontally arranged at interval along track plates 20 in big-inclination curve section.
Referring to Fig.1, Fig. 2, Fig. 3 and Fig. 4, the position limiting structure are the tenon structure downwardly convex by 20 bottom surface of track plates
