Self-anchored suspension bridge construction method adopting cable-stayed cantilever and pushing technology
The invention relates to a self-anchored suspension bridge construction method adopting a cable-stayed cantilever and pushing technology, and belongs to the technical field of bridge construction. The method comprises the following steps that S1, a temporary support is erected, and an anti-collision pier is arranged near the temporary support of a navigation hole; s2, a pushing section steel box girder is erected by the floating crane in a segmented mode, and the pushing section of the steel box girder is pushed in the direction of the navigation hole through a walking type pushing device; s3, a floating crane is matched with a truck crane to assemble a cable-stayed tower and a bridge deck crane; s4, a bridge deck crane is used for hoisting the cantilever assembly section steel box girder; s5, the relative positions of joints between the beam sections are accurately adjusted, then welding construction between the beam sections is conducted, the cable-stayed buckle cables are tensioned, and finally the deck crane moves forwards; s6, the steps S4 to S5 are cyclically carried out until the closure section steel box girder is spliced; s7, assembling a mid-span temporary channel closure section steel box girder by using a deck crane; and S8, the cable-stayed buckle tower and the cable-stayed buckle cable are dismantled through the truck crane, and the deck crane is dismantled.
本发明涉及一种采用斜拉悬臂与顶推技术的自锚式悬索桥施工方法，属于桥梁施工技术领域，包括以下步骤：S1、搭设临时支架，并在通航孔的临时支架附近设置防撞墩；S2、浮吊分段架设顶推段钢箱梁，利用步履式顶推器将钢箱梁顶推段向通航孔方向顶推；S3、利用浮吊配合汽车吊拼装斜拉扣塔及桥面吊机；S4、利用桥面吊机起吊悬臂拼装段钢箱梁；S5、精确调整梁段间接缝相对位置，然后进行梁段间焊接施工，并张拉斜拉扣索，最后桥面吊机前移；S6、循环进行S4～S5，直至进行合龙段钢箱梁的拼装；S7、利用桥面吊机拼装中跨跨临时航道合龙段钢箱梁；S8、利用汽车吊拆除斜拉扣塔及斜拉扣索，并拆除桥面吊机。
