Construction method for arch ring of double-hole concrete arch bridge
The invention discloses a double-hole concrete arch bridge arch ring construction method. The method comprises the following steps that S1, a temporary support is erected, an arch frame is assembled, a rotating disc is installed on a middle arch seat, namely a number arch seat, a vertical rotating support and a first-time vertical rotating buckle cable are installed, and first-time vertical rotating construction is carried out; s2, after the first-time vertical rotation construction is completed, a plurality of second-time vertical rotation buckle cables are adopted to be connected with the arch frame, second-time vertical rotation construction is conducted, and the arch frame is vertically rotated to the designed elevation position; s3, the rotating disc is rotated, the arch frame horizontally rotates along with the rotating disc, and rotation is stopped after the whole rotating disc rotates to the designed axis; s4, splicing and folding the rest arch frame on the right side; s5, adopting the same method in the step S4 to assemble the rest arch frame on the left side; and S6, the buckle cable, the back cable and the cable bent tower are dismantled, the concrete arch ring is poured, the bridge pier is poured after construction of the concrete arch ring is completed, and then the bridge superstructure is constructed. The high-altitude splicing and welding workload is reduced, the construction period is shortened, and construction is simplified. The arch ring is cast into three rings, so that the steel frame consumption is reduced.
本发明公开了双孔砼拱桥拱圈施工方法，包括以下步骤：S1、搭设临时支架，拼装拱架，在中间拱座即号拱座处安装转盘，安装竖转支架及第一次竖转扣索，进行第一次竖转施工。S2、第一次竖转施工完成后，采用多根第二次竖转扣索连接拱架，进行第二次竖转施工，将拱架竖转到设计标高位置；S3、转动转盘，拱架随之平转，整体转动至设计轴线后停止转动；S4、右侧剩余部分拱架拼装合拢；S5、采用步骤S4同样的方法对左侧剩余部分拱架进行拼装；S6拆除扣索、背索、索塔，浇筑混凝土拱圈，混凝土拱圈施工完成，然后浇筑桥墩，然后施工桥梁上部结构。本发明减少了高空拼装、焊接工作量，缩短了工期，简化了施工。拱圈浇筑的时候分三环，减小钢架用量。
