Active pressure-bearing type support replacing and mounting method and device
The invention relates to an active pressure-bearing type support replacing and mounting method and device. The method comprises the following specific construction steps that a new support is mounted, specifically, the new support is mounted below a bridge; a new support is jacked, specifically, the support is driven to move, the support abuts against the bottom wall of the bridge and applies pressure to the bottom wall of the bridge, and pressure applying is stopped till the applied pressure is consistent with the designed pressure value; and new padstone is poured, specifically, the new padstone is formed below the support through pouring, and then support installation can be completed. The method has the effects that the possibility of replacing the support or repairing the bridge can be reduced, building materials can be saved, and the method is green and environment-friendly; the counter-force is obtained by compressing the support from bottom to top, the step that the counter-force is transferred from a jack to the support is omitted, the applied counter-pressure is the pressure actually borne by the support, and therefore the pressure borne by the newly-added support or the replaced support can be precisely controlled.
嫩本申请涉及一种主动承压式更换和安装支座方法及装置，其具体施工步骤如下：安装新支座：将新支座安装在桥梁下方；顶升新支座：驱动支座移动，支座抵触在桥梁底壁上并对桥梁底壁施加压力，直至施加的压力与设计压力值一致，停止施加压力；浇筑新垫石：在支座下方浇筑形成新的垫石，即可完成支座安装。本申请的效果在于可以降低需要更换支座或者修复桥梁的可能性，有利于节约建筑材料，绿色环保；支座“自下而上”压缩获得反力，跳过了支反力由千斤顶向支座转移的这一步骤，施加的反压力即为支座实际承载的压力，从而可以实现新增支座或者更换后的支座承受压力精准可控。
