Double-hanging-buckle construction method of beam-arch combined bridge
The invention relates to the field of beam-arch combined bridges, and discloses a double-hanging-buckle construction method of a beam-arch combined bridge, which comprises the following steps: step 1, completing pier construction, pouring a 0 # section of an upper chord beam at the top of a pier, and mounting an upper chord hanging basket on the 0 # section of the upper chord beam, and step 2, pouring the upper chord beam and a lower chord arch section by section by adopting the hanging basket. Meanwhile, a temporary cable bent tower is erected on the 0 # section of the upper chord beam, a plurality of upper buckling cables are installed on the temporary cable bent tower, and each section of the upper chord beam is connected with the lower ends of the two upper buckling cables; meanwhile, a lower buckle cable is installed on the segment of each lower chord arch, and the middle of each lower buckle cable penetrates through the bridge pier; and thirdly, the hanging basket on the lower chord arch is dismantled, and the folding section is poured through the hanging basket on the upper chord beam. The stress systems of the upper chord beam and the lower chord arch are mutually independent, and the stress balance is prevented from being influenced by the construction progress of the upper chord beam and the lower chord arch.
本发明涉及梁拱组合桥梁领域，公开了梁拱组合桥的双挂扣施工方法，包括以下步骤：步骤一、完成桥墩施工，在桥墩顶部浇筑上弦梁0#段，在上弦梁0#段上安装上弦挂篮，步骤二、采用挂篮分节段浇筑上弦梁和下弦拱；同时，在上弦梁0#段上搭设临时索塔，临时索塔上安装若干上扣索，上弦梁的每个节段分别和两个上扣索下端连接；同时，在每个下弦拱的节段上安装下扣索，下扣索中部穿过桥墩；步骤三、拆除下弦拱上的挂篮，使用上弦梁上的挂篮浇筑合拢段。使上弦梁和下弦拱的受力体系相互独立，避免上弦梁和下弦拱的施工进度影响受力平衡。
