Construction method of arch bridge arch rib
The invention discloses an arch bridge arch rib construction method which specifically comprises the steps of manufacturing arch ribs and completing pre-splicing, installing joint flanges at joints of all arch rib sections, installing arch springing and arch supports, pouring concrete to pre-buried sections of the arch springing, hoisting the arch rib sections on the two sides of the most edge part, tensioning buckle cables, and installing inter-rib parallel braces and cross braces. The arch rib sections in the middle are hoisted, the buckle cables are tensioned, meanwhile, the side wind cables are pulled, and inter-rib parallel braces and cross braces are installed; the method comprises the following steps: folding all arch rib sections into an integral arch rib, welding nodes of the arch rib sections, welding nodes of arch feet, temporarily hinging and sealing the arch feet, removing buckle cables, pouring concrete into the arch rib, mounting on-arch upright posts and cross tie beams among the upright posts, pouring the upright posts with concrete, welding side boxes of the upright posts and pouring concrete, coating finish paint, and removing a cable crane. According to the method, the accuracy of the position of each segment and the linearity of the whole arch rib are guaranteed, operation is convenient and fast, and safety is high.
本发明公开了一种拱桥拱肋的施工方法，具体施工方法为：制作拱肋并完成预拼，在每个拱肋节段接头处安装接头法兰，安装拱脚和拱座，拱脚预埋段混凝土浇注，吊装最边部两侧的拱肋节段，张拉扣索，安装肋间平联及横撑，吊装中间部分的拱肋节段，张拉扣索，同时侧风缆拉设，安装肋间平联及横撑；所有拱肋节段合拢成整体拱肋，焊接拱肋节段节点，焊接拱脚节点，拱脚临时铰封铰，拆除扣索，拱肋混凝土灌注，安装拱上立柱和立柱间横系梁，混凝土灌注立柱，立柱柱脚边箱焊接及砼浇筑，面漆涂装，拆除缆索吊机。本发明保证了每分节段位置的准确性和整体拱肋的线性，操作便捷，安全性高。
