Cast-in-place and prefabrication combined structure for on-bridge rail connection and construction method thereof
The invention discloses a cast-in-place and prefabrication combined structure for on-bridge rail connection, which is used for realizing rail connection of a newly-built railway and an existing line on the bridge and comprises large frames of a cast-in-place structure and small frames of a prefabricated structure. The cast-in-place large frames are arranged between two adjacent bridge piers of the existing line, the width of the cast-in-place large frames are larger than that of an original existing line bridge, and the cast-in-place large frames are eccentrically arranged towards a newly-built railway on the outer side. The lower portions of the large frames are reinforced through pile foundations, and the upper end faces of the large frames are flush with the upper end faces of the piers. A plurality of prefabricated small frames are transversely arranged on the large frames and arranged between every two adjacent large frames and on the bridge piers in a spanning mode. A newly-built railway, an existing line and a turnout device are arranged above the small frames and used as a bridge of the newly-built railway and the existing line. The method solves the problem of on-bridge rail connection, the construction period can be greatly shortened, the existing line outage time is shortened, and the social cost is reduced.
本发明公开了一种现浇、预制相结合的桥上接轨的组合结构，用于新建铁路与既有线在桥上实现接轨，包括现浇结构的大框架、预制结构的小框架；现浇的大框架设置在既有线相邻的两个桥墩之间，且其宽度大于原既有线桥梁的宽度，并向外侧的新建铁路偏心设置；大框架的下部通过桩基加固，其上端面与桥墩的上端面平齐；预制的若干小框架横向设置在大框架上，以及跨设在相邻两个大框架之间和桥墩之上；小框架的上方设置新建铁路、既有线及道岔装置，作为新建铁路与既有线的桥梁使用。本发明解决了桥上接轨问题，可以极大的节省施工周期，减少既有线停运时间，降低社会成本。
