Temporary supporting structure for replacing bridge support
The temporary supporting structure comprises jacking devices and transverse limiting devices, the jacking devices and the transverse limiting devices are symmetrically arranged between a pier and a main beam, and each jacking device is provided with a plurality of synchronous jacking hydraulic jacks distributed in a matrix mode. Each synchronous jacking hydraulic jack is connected to a PLC multi-point synchronous lifting control system through a hydraulic pipe, a supporting cushion block is arranged between each synchronous jacking hydraulic jack and a bridge pier, and the upper portions of the synchronous jacking hydraulic jacks distributed in the same row in the longitudinal bridge direction are jointly connected with a transverse limiting device. Each transverse limiting device comprises a first base plate, a stainless steel plate, a polytetrafluoroethylene sliding plate and a second base plate which are sequentially distributed from top to bottom, and limiting strips protruding downwards are arranged on the two sides of the first base plate in the transverse bridge direction. The method is suitable for being applied to the situation that the supporting bridge needs to be jacked for a long time to replace the support, the traffic control cost is low, operability is high, and the technology is safe and reliable.
本发明公开了一种用于更换桥梁支座作业的临时支撑结构，包括对称布置在桥墩与主梁之间的顶升装置和横向限位装置，每组顶升装置设有多个矩阵分布的同步顶升液压千斤顶，各个同步顶升液压千斤顶通过液压管连接至PLC多点同步升降控制系统，每个同步顶升液压千斤顶与桥墩之间垫有支撑垫块，沿纵桥向方向分布的同一列同步顶升液压千斤顶的上方共同连接有一个横向限位装置，每个横向限位装置包括自上而下依次分布的第一垫板、不锈钢板、聚四氟乙烯滑板和第二垫板，第一垫板沿横桥向方向的两侧设有向下凸出分布的限位条。本发明适合应用于需要长时间顶升支撑桥梁进行更换支座作业的情形，交通管制成本低，操作性强，技术安全可靠。
