Drainage structure of railway double-layer frame pier
The invention discloses a railway double-layer frame pier drainage structure which comprises a lower cross beam and an upper cross beam which are parallel to each other, a lower-layer beam body is arranged at the upper end of the lower cross beam, an upper-layer beam body is arranged at the upper end of the upper cross beam, a lower drainage structure is arranged at the upper end of the lower cross beam, and an upper drainage structure is arranged at the upper end of the upper cross beam. A vertical drainage structure is arranged on the outer side of a pier column of the double-layer frame pier. The water retaining platform is arranged on the outer side of the upper cross beam in the line direction, so that water accumulated on the top of the upper cross beam is discharged from the two ends of the upper cross beam along the water retaining platform, and the problem that a double-layer frame pier possibly affects running of a lower-layer line due to falling of ice in winter is solved. The upper and lower layer combined drainage pipes are arranged along the top surfaces of the upper and lower cross beams of the double-layer frame pier and the outer side of the pier column, so that the problem that the frame pier drainage pipes fall to influence running of a lower layer line is solved; and the upper cross beam drainage pipe is positioned between the water retaining tables, so that the risk that the upper cross beam drainage pipe is damaged by longitudinal wind load is reduced.
本发明公开了一种铁路双层框架墩排水结构，包括下横梁、上横梁，所述下横梁、上横梁相互平行，下横梁上端设置有下层梁体，上横梁上端设置有上层梁体，下横梁上端设置有下排水结构，上横梁上端设置有上排水结构，双层框架墩的墩柱外侧设置有竖向排水结构。本发明的上横梁在顺线路方向外侧设置挡水台，使得上横梁顶面积水沿挡水台从上横梁两端排出，解决了双层框架墩可能因冬季冰凌坠落影响下层线路行车的问题。本发明采用上下层组合式排水管，将排水管沿双层框架墩的上、下横梁顶面和墩柱外侧布置，解决了框架墩排水管坠落影响下层线路行车的问题；并且改后上横梁排水管位于挡水台之间，降低了上横梁排水管受纵向风荷载的破坏风险。
