Arched bridge construction method
The invention discloses an arched bridge construction method, which comprises the following steps of: constructing a steel pipe bracket in an arched bridge prefabrication site, and mounting an arch rib of an arched bridge on the steel pipe bracket to complete the assembly of an arched bridge framework; slings are installed in the extending direction of the arched bridge, and temporary cross beams are installed, so that the framework structure of the arched bridge is stable; the arched bridge framework is hoisted through a floating crane so that the arched bridge framework can be moved to the bridge piers in place, and the arched bridge framework is supported through the bridge pier supports so that the arched bridge framework can be stably fixed to the bridge piers; arch springing supports are erected on the bridge piers so that pouring construction can be conducted on arch springing and the two ends of the bridge; and the arch foot supports are dismantled, and pouring construction is conducted on the full bridge and the tied arches. According to the arch bridge construction method, the arch bridge framework is independently constructed, a steel pipe support does not need to be erected in the river channel, the influence on the river channel is reduced, the construction period is greatly shortened, and the construction cost is reduced.
本发明公开了一种拱形桥梁施工方法，该方法通过在拱形桥梁预制场地内进行钢管支架施工，并在钢管支架上安装拱形桥梁的拱肋，以完成拱形桥梁骨架拼装；沿拱形桥梁的延伸方向安装吊索，并安装临时横梁，以使拱形桥梁的骨架结构稳固；通过浮吊吊装拱形桥梁骨架，以将拱形桥梁骨架移动就位至桥墩上，并通过桥墩支座对拱形桥梁骨架支撑，以使拱形桥梁骨架稳固在桥墩上；在桥墩上搭设拱脚支架，以对拱脚和桥梁两端进行浇筑施工；拆除拱脚支架，并对全桥和系杆拱进行浇筑施工。本发明的拱形桥梁施工方法拱形桥梁骨架单独施工，无需在河道内架设钢管支架，降低了对河道的影响，且极大地缩短了施工工期，降低了施工成本。
