The lowest point of the V-slope line 12 is point A, and the horizontally corresponding point of the lowest point of the V-slope line 12 on the single-slope line 13 is point B. First longitudinal drainage ditches 51 are provided on both sides of the length direction of the V-slope line 12, and second longitudinal drainage ditches 52 are provided on both sides of the length direction of the single-slope line 13. The water in the single-slope line 13 is discharged by the second longitudinal drainage ditch 52.

The water in the V-slope line 12 is discharged after passing through the first longitudinal drainage ditch 51, point A, the inter-line transverse drainage ditch 3, point B, and the second longitudinal drainage ditch 52 in sequence.

[0026] The transverse drainage ditch 3 between the lines is set to drain the accumulated water from the lowest point (A) of the V-slope line 12 to the single-slope line 13 (B), and then drain it through the second longitudinal drainage ditch 52 of the single-slope line 13. It is not necessary to set a wastewater pool at the lowest point (A) of the V-slope line 12, and no water pump is required, which saves the engineering cost.

[0027] Furthermore, in order for the wastewater in the first longitudinal drainage ditch 51 to be discharged through the second longitudinal drainage ditch 52 , the elevation at point A needs to be higher than or equal to the elevation at point B.

[0028] Furthermore, a first sump 21 is provided at A and close to the single slope line 13, and a second sump 22 is provided at B and close to the V slope line 12.

Preferably, there are multiple inter-line transverse drainage ditches 3, and the number of inter-line transverse drainage ditches 3 is determined according to drainage requirements. Preferably, in order to drain water smoothly, the slope of the inter-line transverse drainage ditch 3 is not less than 0.2%.

[0032] Furthermore, there is a subway structure 1 between the V-slope line 12 and the single-slope line 13, and the subway structure 1 has a reserved structural opening 7, and the inter-line transverse drainage ditch 3 passes through the structural opening 7. The number and size of the structural openings 7 must meet the requirements for setting the inter-line transverse drainage ditch 3.

[0034] A plurality of second sleepers 11 are laid on the single slope line 13. Two second longitudinal drainage ditches 52 are connected by a second ballast bed transverse drainage ditch 42. The second ballast bed transverse drainage ditch 42 is arranged between two adjacent second sleepers 11. The number of the second ballast bed transverse drainage ditches 42 is determined according to drainage requirements.

[0035] The wastewater in the first longitudinal drainage ditch 51 on the side of the V-slope line 12 far from the single-slope line 13 flows into the first sump 21 through the first ballast transverse drainage ditch 41 at point A, and the wastewater in the first longitudinal drainage ditch 51 on the side of the V-slope line 12 close to the single-slope line 13 flows directly into the first sump 21. The wastewater in the first sump 21 flows into the second sump 22 through the inter-line transverse drainage ditch 3. A part of the wastewater from the higher end of the single-slope line 13 is directly discharged through the second longitudinal drainage ditch 52 far from the side of the V-slope line 12, and another part of the wastewater from the higher end of the single-slope line 13 flows into the second sump 22 through the second longitudinal drainage ditch 52 close to the side of the V-slope line 12. A part of the wastewater in the second sump 22 is then discharged through the second ballast transverse drainage ditch 42 and the second longitudinal drainage ditch 52 far from the side of the V-slope line 12, and another part of the wastewater in the second sump 22 is directly discharged through the second longitudinal drainage ditch 52 close to the side away from the V-slope line 12.

[0036] Furthermore, in order to drain water smoothly, the first longitudinal drainage ditch 51, the second longitudinal drainage ditch 52, the first ballast bed transverse drainage ditch 41 and the second ballast bed transverse drainage ditch 42 should have a certain slope.

[0037] Furthermore, a grille or a steel cover is provided above the first sump 21 and the second sump 22. The grille or the steel cover can prevent debris from falling into the first sump 21 or the second sump 22 from above.

[0038] Furthermore, an iron grate 6 is provided at the position where the first sump 21 is connected to the first longitudinal drainage ditch 51, and an iron grate 6 is provided at the position where the first sump 21 is connected to the inter-line transverse drainage ditch 3; an iron grate 6 is provided at the position where the second sump 22 is connected to the second longitudinal drainage ditch 52, and an iron grate 6 is provided at the position where the second sump 22 is connected to the second track bed transverse drainage ditch 42.
