Bridge incremental launching construction method
The invention relates to the technical field of bridge construction, in particular to a bridge incremental launching construction method. The method comprising the steps that S1, rails are laid, specifically, the rails are laid below a bridge according to the projection position of the bridge, the ground needs to be compacted before laying, sleepers are laid, and then a guide rail is laid on the sleepers; S2, a temporary pier is manufactured, specifically, a sliding plate is arranged at the upper end of the guide rail, a pier body is poured at the upper end of the sliding plate, a jack is arranged at the upper end of the pier body, and meanwhile a traction part and a fixing part are arranged on the pier body; S3, the temporary pier is positioned, specifically, the temporary pier is moved to a specified position according to a drawing, and the temporary pier is fixed; and S4, the height of the tops of the temporary piers is adjusted according to the pre-camber curve of the bridge bottom, and bridge sections are spliced. Through a bridge pushing method, the construction precision of bridge installation can be effectively improved, the situation that deviation needs to be corrected is reduced or avoided, the construction efficiency is effectively improved, the whole operation process is relatively simple, the construction period is short, the construction cost is relatively low, and the method is suitable for popularization and use.
本发明涉及桥梁施工技术领域，尤其涉及S1、铺设轨道：在桥梁的下方，根据桥梁的投影位置，铺设轨道，铺设前需对地面压实，并铺设枕木，然后在枕木上铺设导轨；S2、临时墩制作：在导轨的上端设置滑板，在滑板的上端浇注墩体，并在墩体的上端设置千斤顶，同时在墩体上设置牵引部和固定部；S3、临时墩定位：根据图纸，移动临时墩至指定的位置，并将临时墩固定住；S4、桥梁顶推：根据桥梁梁底预拱度曲线，调整临时墩顶部的高度，进行桥梁梁段拼装，通过该桥梁顶推方法，能够有效的提高桥梁安装的施工精度，减少或者避免了需要纠偏的情况，有效的提高了施工效率，且整个操作过程相对简单，施工周期短，施工成本相对较低，适合推广使用。
