Staged multi-jack synchronous tensioning method
The invention discloses a staged multi-jack synchronous tensioning method. The staged multi-jack synchronous tensioning method comprises the following steps: numbering hydraulic pump stations in the synchronous tensioning system and oil outlets of the hydraulic pump stations; tensioning jacks are connected with the numbered oil outlets respectively; relevant parameters are set in the synchronous tensioning system; the synchronous tensioning system starts synchronous tensioning, and after the real-time force value of the oil outlet reaches the target force value of the current stage, the oil outlet keeps load and supplements oil; if the percentage of the oil inlet force value of the current stage is smaller than or equal to 100%, the tensioning process is controlled to enter the fifth step; if the percentage of the oil inlet force value at the current stage is larger than 100%, the tensioning process is controlled to jump out of circulation, and oil inlet is ended; and oil returning is completed, and synchronous tensioning is completed. According to the staged multi-jack synchronous tensioning method, the force value precision is high, the bridge tensioning construction period can be greatly shortened, and the service life of the whole bridge can be prolonged.
本发明公开了一种阶段性多顶同步张拉的方法。该阶段性多顶同步张拉的方法包括以下步骤：对同步张拉系统中的液压泵站以及液压泵站的出油口进行编号；将张拉千斤顶分别与已编号的出油口进行连；在同步张拉系统中分别设置相关参数；同步张拉系统启动同步张拉，当出油口的实时力值达到当前阶段目标力值后，出油口持荷补油；进入下一阶段，当前阶段的进油力值百分比小于等于100%，则控制张拉流程进入所述步骤五；若当前阶段的进油力值百分比大于100%，则控制张拉流程跳出循环，结束进油；完成退油，同步张拉完成。本发明提供一种阶段性多顶同步张拉的方法，力值精度高，能大幅度缩短桥梁张拉工期，能提高整座桥的使用寿命。
