FIELD: overpasses for rail tracks. SUBSTANCE: elevated track has girders 10 resting on pillars 12, 14 which are installed on foundation embedded in ground 16. Pillars 12,14 are located at opposite sides 34, 36 of girders and arranged in pairs. To ensure required alignment of track, pillars 12, 14 which are corresponding to each other in pairs, are spaced from each other at ground level at distance which is less than distance at girder sides. Pillars are made for possible controlled displacement in required degree in plane perpendicular to longitudinal axis of track 18. Thus, track is laid at incline to horizon. EFFECT: high efficiency. |
