The positioning column 16 is only used for positioning requirement when the rail 5 is installed, so as to ensure the installation accuracy between the rail 5 and the whole sleeper structure 6.

[0031] The two ends of the rail 5 are provided with inner bearing seats 7, the inner end of the side connecting rod 9 is connected with the inner bearing seat 7, and the outer side of the inner bearing seat 7 is provided with an outer sealing plate 8 corresponding to the elastic bearing plate 12.
