[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A reverse siphon pipeline system for a municipal road crossing an agricultural water conservancy ditch comprises an inlet pool, a culvert section and an outlet pool, wherein the inlet pool is connected to the culvert section, and the culvert section is connected to the outlet pool; the inlet pool and the outlet pool comprise concrete retaining walls and concrete wing walls, and a concrete bottom plate is arranged at the bottom; the outer sides of the inlet pool and the outlet pool are connected to concrete bottom protection, and the ends of the concrete bottom protection are provided with anti-scour embedded platforms; the culvert section comprises a circular culvert with the same length and aperture; the outer sides of the inlet pool and the outlet pool are connected to the concrete bottom protection which is higher than the culvert, and the bottom surfaces of the inlet pool and the outlet pool are both slope surfaces; a concrete cover plate is arranged on the culvert section, cover plate fill is arranged on the cover plate, and a road structure layer is arranged on the fill.

[0006] Furthermore, retaining walls are provided at the connections between the water inlet pool, the water outlet pool and the culvert section, and the height of the retaining wall is equal to the height of the wing wall.

[0007] Furthermore, the wing wall (13) is a straight-line wing wall.

[0008] Furthermore, the reinforced concrete cover plate (6) provided on the culvert section (3) has a thickness of 200 mm, the cover plate fill (7) has a thickness of 400 mm, and the compaction degree of the cover plate fill (7) is not less than 0.96.

[0009] Furthermore, asphalt sealing mortar (10) is used to seal the four sides of the interface between the culvert section (3) and the concrete retaining wall (11) of the water inlet pool (1) and the water outlet pool (2).

[0010] The inverted siphon pipe system of this municipal road crossing the farmland water conservancy ditch has a simple structure and is easy to construct. It uses the water's own gravity to flow smoothly, has a low cost, is easy to construct, and is easy to maintain in the later stage. It effectively solves the problem that the elevation of the farmland water conservancy irrigation channel is higher than the design road elevation and the direction of the irrigation channel cannot be changed during the municipal road construction process, and is more practical.
