Inter-line drainage structure for medium-and-low-speed magnetic-levitation low-altitude double-line district

The invention discloses an inter-line drainage structure for a medium-and-low-speed magnetic-levitation low-altitude double-line district. The inter-line drainage structure for the medium-and-low-speed magnetic-levitation low-altitude double-line district comprises a foundation bed, an inter-line drainage device, high-voltage cable supporting bases and a water guiding layer. The foundation bed is arranged on a roadbed. The inter-line drainage device is arranged in a drainage groove of the foundation bed and comprises a base plate, a first vertical wall, a second vertical wall, first drainage holes and vertical wall bosses. The first vertical wall and the second vertical wall are provided with the multiple first drainage holes penetrating through the first vertical wall and the second vertical wall correspondingly. The number of the high-voltage cable supporting bases is consistent with the number of the vertical bosses. The water guiding layer is arranged on the top end face of the foundation bed and used for guiding water into a drainage channel of the inter-line drainage device. The inter-line drainage structure for the medium-and-low-speed magnetic-levitation low-altitude double-line district can be well adapted to inter-line drainage and cable laying of magnetic-levitation traffic engineering, and long-term stability and durability of the foundation bed can be guaranteed.
