Temporary pier jacking and heightening bridge construction system and heightening construction method
The invention relates to a bridge construction system for jacking and heightening of a temporary pier and a heightening construction method.The bridge construction system comprises the temporary pier, the temporary pier comprises a pier top section, a pier foundation and a heightening section, and the heightening section is detachably connected with the pier top section and the pier foundation; the heightening section comprises a plurality of heightening sections which are detachably connected; the heightening support is installed above the pier foundation, and the heightening support is provided with a plurality of installation structures at intervals in the vertical direction; the jacking jack comprises a first counter-force base, a telescopic part and a second counter-force base which are sequentially connected from top to bottom, the first counter-force base is detachably installed on one of the installation structures, and the second counter-force base is fixedly connected with the pier top section. The jacking jack with small jacking amount can be adopted to realize the heightening work of the temporary pier, the heightening device of the temporary pier can be conveniently arranged, and the heightening difficulty of the temporary pier is reduced.
本发明涉及一种临时墩顶升接高的桥梁施工系统以及接高施工方法，桥梁施工系统包括：临时墩，所述临时墩包括墩顶段、墩基础以及接高段，所述接高段可拆卸的连接所述墩顶段以及所述墩基础,所述接高段包括可拆卸相连的多段接高节段；接高支架，所述接高支架安装于所述墩基础上方，所述接高支架沿竖向间隔设有多个安装结构；顶升千斤顶，所述顶升千斤顶包括由高至低依次相连的第一反力座、伸缩部以及第二反力座，其中，所述第一反力座可拆卸的安装于其中一个所述安装结构上，所述第二反力座与所述墩顶段固定连接。可采用顶升量较小的顶升千斤顶实现临时墩的接高工作，可方便的布置临时墩的接高装置，降低了临时墩的接高难度。
