Construction method for replacing bridge support through multi-point synchronous jacking
The invention relates to the technical field of bridge support replacement, and provides a construction method for replacing a bridge support through multi-point synchronous jacking, which comprises the following steps: S1, removing a connecting piece between a single-connection beam body in the longitudinal direction and the transverse direction; S2, installing a hydraulic synchronous jacking system; S3, debugging the hydraulic synchronous jacking system in a pre-jacking mode; S4, controlling a hydraulic synchronous jacking system to synchronously jack the beam body to a preset height; then, arranging temporary supporting pieces on the bent cap; S5, dismounting an original bridge support; mounting the new bridge support on the padstone; S6, dismantling the temporary supporting pieces on the bent cap; and controlling the hydraulic synchronous jacking system to enable the beam body to synchronously fall on the new bridge support. According to the method, when the bridge support is replaced, synchronous jacking and synchronous beam falling of the beam body can be achieved, additional internal stress is prevented from being generated in the beam body, deformation or damage of the beam body is prevented, and the service life and safety of a bridge are guaranteed.
本发明涉及桥梁支座更换技术领域，提供了一种多点同步顶升更换桥梁支座的施工方法，包括如下步骤：S1、解除单联梁体纵横向间的连接件；S2、安装液压同步顶升系统；S3、采用预顶升的方式对所述液压同步顶升系统进行调试；S4、控制液压同步顶升系统将梁体同步顶升至预定高度；然后在盖梁上布置临时支撑件；S5、拆除原桥梁支座；新桥梁支座安装至垫石上；S6、拆除盖梁上的临时支撑件；控制液压同步顶升系统将梁体同步下落在新桥梁支座上。本发明的方法，在更换桥梁支座时，可实现梁体的同步顶升和同步落梁，避免在梁体内产生附加内应力，防止了梁体变形或损坏，保证了桥梁的使用寿命和安全。
