Bridge pier column lifting and reinforcing device and construction method
The bridge pier column lifting and reinforcing device comprises an upper holding mechanism and a lower holding mechanism, each holding mechanism comprises a front holding plate and a rear holding plate, and supporting plates in the horizontal direction are fixed to the lower end face of the upper holding plate and the upper end face of the lower holding plate correspondingly; a plurality of vertically-arranged hydraulic cylinders are arranged between the supporting plates on the upper side and the lower side, a positioning block is arranged between every two hydraulic cylinders and located in the middle of the interval between the supporting plates on the upper side and the lower side all the time, a positioning plate is fixed to the end face of the inner side of each supporting plate, and the inner side face of each positioning block is attached to the outer edge face of the corresponding positioning plate all the time. When the upper holding mechanism and the lower holding mechanism are far away from each other, the positioning blocks apply inward extrusion force to the positioning plates, and the larger the distance is, the larger the extrusion force is. The positioning blocks in multiple directions are arranged to continuously apply inward extrusion force to the positioning plate in the jacking period, it is guaranteed that the upper pier column does not deviate from the axis in the jacking process, and the situation that the overall supporting strength of the pier column is affected by axis deviation is avoided.
本发明涉及一种桥梁墩柱抬高加固装置及施工方法，包括上下两组抱紧机构，每组抱紧机构包括前后两个抱紧板，上侧抱紧板的下端面和下侧抱紧板的上端面分别固定有水平方向的支撑板，上下两侧的支撑板之间设置有多个竖直放置的液压缸，每两个液压缸之间分别设置有一个定位块，定位块始终位于上下两侧支撑板间隔中部，每个支撑板内侧端面固定有定位板，定位块的内侧面始终与定位板的外缘面贴合，当上下两组抱紧机构相互远离时，定位块对定位板一个向内的挤压力，且远离间隔越大，挤压力越大；本发明通过设置多个方位的定位块在顶升期间持续对定位板施加向内侧的挤压力，保证上段墩柱顶升过程中不偏离轴线，避免轴线偏离影响墩柱整体支撑强度。
