Bridge support replacing device and replacing method
The invention relates to the technical field of bridge construction, and discloses a bridge support replacing device and method. The bridge support replacing device comprises a synchronous hydraulic jacking device and a displacement monitoring device, the synchronous hydraulic jacking device comprises a hydraulic control system and a plurality of jacks, the tops of pistons of the jacks are provided with arc-shaped groove structures, arc-shaped protruding structures are rotationally connected into the arc-shaped groove structures, and the arc-shaped protruding structures are used for supporting the bottom of a bridge. Two steel base plates are arranged between the arc-shaped protruding structure and the bottom of the bridge in a clamped mode, a polytetrafluoroethylene sliding plate is arranged between the two steel base plates in a clamped mode, a piston of the jack is mechanically self-locked through a threaded self-locking flange plate, and the displacement monitoring device is used for monitoring elevation changes before and after replacement of the bridge support. When the bridge support is repaired and replaced, the top of the jack can slide properly to adapt to and improve the stress condition of a bridge in use, traffic does not need to be interrupted in the repairing period, and the device is high in controllable precision, safe, reliable, easy to operate, economical and efficient.
本发明涉及桥梁施工技术领域，公开一种桥梁支座更换装置及更换方法。所述桥梁支座更换装置包括同步液压顶升设备和位移监测设备，同步液压顶升设备包括液压控制系统以及若干个千斤顶，千斤顶的活塞顶部具有弧形凹槽结构，弧形凹槽结构内转动连接有弧形凸起结构，弧形凸起结构用于支撑桥梁梁底，弧形凸起结构与桥梁梁底之间夹设有两个钢垫板，两个钢垫板之间夹设有四氟滑板，千斤顶的活塞通过螺纹自锁法兰盘进行机械自锁，位移监测设备用于监测桥梁支座更换前后的标高变化。本发明在修复和更换桥梁支座时，千斤顶顶部可适当滑动，适应和改善桥梁在使用时的受力状况，在修复期间无需中断交通，可控精度高，安全可靠，操作简单，经济高效。
