Bridge body slippage resetting method
The invention discloses a bridge body slippage resetting method. The method comprises the following steps that S1, the resetting position of a bridge body is determined; and S2, the beam body is jacked through a jacking system. And S3, a leveling steel plate, a stainless steel plate and a polytetrafluoroethylene sliding plate are additionally arranged at the bottom of the beam body, and then the beam body falls down. And S4, a bridge deck reaction frame is manufactured, and a jack system is installed. And S5, the beam body is synchronously pushed, and a temporary support is arranged. And S6, the beam body is continuously pushed through the jack system, and the stainless steel plate, the polytetrafluoroethylene sliding plate and the old support are dismantled one by one. And S7, a new support is installed, and the temporary support is dismantled. And S8, after the jack system is used for falling the beam, a beam body limiter is installed, and the bridge deck reaction frame and the jack system are dismantled. The jacking force is determined through checking calculation before construction, and the jacking force and the jacking speed are controlled through the jack, so that the internal stress and elastic deformation of the beam body are fully released, the construction precision is improved, and the safety of the beam body is ensured.
本发明公开了一种桥梁梁体滑移复位方法，包括以下步骤:S1、确定梁体的复位位置。S2、采用顶升系统对梁体进行顶升。S3、在梁体底部增设调平钢板，加设不锈钢板和四氟滑板，再使梁体落下。S4、制作桥面反力架，并安装千斤顶系统。S5、同步顶推梁体，并设置临时支撑。S6、利用千斤顶系统继续顶推梁体，并逐一拆除不锈钢板、四氟滑板和旧支座。S7、安装新支座，并拆除临时支撑。S8、利用千斤顶系统落梁后，安装梁体限位器，并拆除桥面反力架和千斤顶系统。通过施工前进行验算，确定顶推力，通过千斤顶控制顶推力和顶推速度，让梁体内部应力及弹性形变充分释放，提高了施工精度，保证了梁体的安全性。
