Vertical rotation construction method for steel arch frame of reinforced concrete arch bridge
The invention discloses a vertical rotation construction method for a steel arch frame of a reinforced concrete arch bridge, which comprises the following steps of: dividing the steel arch frame into four sections, respectively assembling two sections of steel arch frames on two banks, and installing steel arches capable of rotating around arch feet at arch seats at two ends. And after all the sections are assembled, the steel arch frame is subjected to vertical rotation construction in a jack and buckle cable mode, folding is conducted after the steel arch frame is vertically rotated to the designed position, the arch axis is remeasured, and reinforced concrete arch ring construction is conducted after rechecking is completed. The steel arch is firstly assembled in sections and then is vertically rotated and constructed in place by adopting the jack and the buckle cable, so that high-altitude operation can be reduced, the construction safety risk is reduced, the requirement on hoisting equipment is reduced, the on-site steel arch assembling efficiency and the steel arch welding quality are effectively improved, and the construction period is shortened.
本发明公开了一种钢筋混凝土拱桥钢拱架竖转施工方法，该方法将钢拱架分为四个节段，在两岸分别各拼装两个节段钢拱架，在两端的拱座处安装可绕拱脚转动的钢拱。各节段拼装完成后，采用千斤顶+扣索的形式对钢拱架进行竖转施工，竖转到设计位置后进行合拢，并对拱轴线进行复测，复核完成后进行钢筋混凝土拱圈施工。钢拱架先分节段拼装再采用千斤顶+扣索进行竖转施工到位可减少高空作业，降低施工安全风险，降低对起重设备的要求，有效提高现场钢拱架拼装效率及钢拱架焊接质量，缩短工期。
