Integral sliding dismounting and mounting method for superstructure of overpass bridge
The invention discloses an integral sliding dismounting and mounting method for an overpass bridge superstructure, and belongs to the technical field of bridge engineering. The method comprises the steps that a, a to-be-disassembled bridge is integrally lifted and separated from a bridge support through a translation system and a lifting and lowering system; b, the to-be-disassembled bridge is made to move towards the disassembling and assembling platform through a translation system, a lifting and lowering system and a sliding system; c, dismantling the beam body on the dismantling and assembling platform to complete dismantling of the old bridge; d, assembling a new beam upper structure and placing the new beam upper structure at a preset position of the sliding system; e, the to-be-installed new beam is made to move towards the to-be-installed bridge span direction through the translation system, the lifting and lowering system and the sliding system; and f, when reaching the preset position, synchronously lowering the falling beam to complete the whole installation of the new bridge overpass bridge. The integral old bridge dismantling and new bridge installing can be completed at the same time, the dismantling and assembling platform is arranged on the site within the range of the existing bridge red lines on the two sides of the overpass bridge, and the influence on the surrounding traffic and social environment is reduced.
本发明公开了一种跨线桥梁上部结构整体式滑移拆除及安装方法，属于桥梁工程技术领域。所述方法包括：a.利用平移系统及提升与下放系统使待拆桥梁整体提升并脱离桥梁支座；b.利用平移系统、提升与下放系统及滑移系统使待拆桥梁向拆解及组拼平台移动；c.在拆解及组拼平台上进行拆解梁体完成旧桥拆除；d.拼装好新梁上部结构并放置在滑移系统预定位置；e.利用平移系统、提升与下放系统及滑移系统使待装新梁向待安装的桥跨方向移动；f.到达预定位置同步下放落梁，完成新桥跨线桥梁整体安装。本发明能同时完成整体式旧桥拆除和新桥安装，并利用跨线桥两侧既有桥梁红线范围内的场地设置拆解及组拼平台，减小对周边的交通和社会环境的影响。
