Embodiment Construction
[0049] figure 1 It is a configuration diagram showing Embodiment 1 of the present invention. figure 2 is along figure 1 A cross-sectional view taken along line A-A in . Figure 3A with 3BIt is a diagram showing the distribution state of the ballast pressure of the ladder-type sleeper track structure of Example 1 and the distribution state of the ballast pressure of the conventional transverse sleeper-type track structure, respectively. In the figure, 1 is a ladder-type sleeper, 2 is a longitudinal beam, 3 is a connector connecting the longitudinal beam 2, 4 is a rail, and 5 is a rail pad placed between the rail 4 and the longitudinal beam 2 to absorb vibration (such as elastic material made of calibration film), 6 is the ballast buried in the ladder sleeper, 7 is the rail fastening device for connecting the rail 4 to the longitudinal beam 2, 8 is a conventional transverse sleeper, 10 is a wheel.
[0050] The ladder-type sleeper 1 of this embodiment comprises a pair of lo...
