Bridge box girder large-span pushing sliding system and construction method
The invention relates to a large-span pushing and sliding system and method for a bridge box girder. The system comprises a shore-based supporting and sliding system arranged on the river-crossing/railway-crossing/highway-crossing ground, and is characterized in that the system comprises, a midspan support sliding rail system which is arranged on a midspan pier bearing platform crossing a river channel/a railway/a highway; the mid-span supporting sliding rail system comprises a mid-span pushing sliding platform, a mid-span sliding rail, a supporting frame, a connecting assembly, a set of sliding shoes and a self-locking synchronous mid-span pushing device, wherein the supporting frame and the connecting assembly are used for supporting the mid-span pushing sliding platform. The system hasthe advantages that the steel pipe trusses are arranged on the permanent piers instead of river bottom foundations, so that the height is reduced, possible deviation and stability increase in the pushing process are prevented, the steel consumption of the trusses is greatly reduced, secondary construction of temporary facilities for pushing and sliding river channel supports is avoided, the construction cost is greatly reduced, the construction period is greatly shortened, and the method is safe and reliable.
本发明涉及一种桥箱梁大跨度顶推滑移系统及方法，包括设置在跨河道/跨铁路/跨公路地面上的岸基支撑滑移系统，其特征在于，还包括设置在跨河道/跨铁路/跨公路的跨中桥墩承台上的跨中支撑滑移轨道系统,所述的跨中支撑滑移轨道系统包括跨中顶推滑移平台、跨中滑移轨道、用于支撑跨中顶推滑移平台的支撑架及连接组件、一组滑靴和自锁同步跨中顶推装置。其优点是：由于钢管桁架是设置于永久桥墩之上，而非河底基础，减少了高度，防止了顶推过程可能出现的偏移，稳定性增加，桁架的用钢量大大降低，避免了顶推滑移河道支撑临时设施的二次施工，大大减少了施工费用和施工工期，安全可靠。
