Variable-span pier stud box girder for rail transit
The invention discloses a variable-span pier stud box girder for rail transit. A pier column box girder of a symmetrical cantilever structure is arranged on a pier column in a prefabricated or cast-in-place mode, the length of the pier column box girder can be set according to the requirement of the road span, a track bed can be prefabricated or cast-in-place at the top of the pier column box girder, and the two ends of the pier column box girder can be connected with another pier column box girder by installing simply-supported beams. In a three-dimensional traffic mode of large and medium-sized cities, due to the facts that the road intersection condition is complex, a variable-span position generally adopts a cast-in-place structure, the cost is high, and the construction time is long,the variable-span problem within 15 m can be solved, the field construction time is shortened, and the cost is reduced by adopting the scheme.
本发明公开了一种轨道交通变跨径墩柱箱梁，是通过预制或现浇的方式在墩柱上面设置了一个呈对称悬臂结构的墩柱箱梁，该墩柱箱梁的长度可根据道路跨度的需求进行设置，在其顶部可以通过预制或现浇轨道床，墩柱箱梁的两端可通过安装简支梁与另一个墩柱箱梁衔接。在大中型城市的立体交通方式中，由于道路交汇情况复杂，变跨径处一般采用现浇结构，成本很高、施工时间长，而采用本方案就能够解决15m以内的变跨径问题，并缩短现场施工时间和降低成本。
