Three-leaf rose-shaped concrete-filled steel tube flying swallow type cable-stayed arch bridge and construction method
The invention provides a three-leaf rose-shaped concrete-filled steel tube flying swallow type cable-stayed arch bridge and a construction method thereof. Steel tubes are bent into three-leaf rose-shaped flying swallow type cable-stayed arch ribs according to a three-leaf rose-shaped line graph by adopting a fire work simmering and bending process for a three-fork river terrain, and a three-fork bridge deck is suspended, so that the three-leaf rose-shaped concrete-filled steel tube flying swallow type cable-stayed arch bridge is formed. Inhaul cables are arranged between the arch feet, inter-arch-rib inhaul cables are arranged between the three-leaf rose-shaped space arch ribs, a self-balancing structure system is formed, floating transportation and dragging are conducted to cross a river,the three-leaf rose-shaped flying swallow type cable-stayed arch ribs are stably located on an arch bridge foundation, main arch slings and tail stayed cables are arranged on the three-leaf rose-shaped flying swallow type cable-stayed arch ribs, a three-fork bridge deck is suspended and assembled, and construction is convenient. The arch foot inhaul cables, the inter-arch-rib inhaul cables, the main arch slings and the tail stayed cables form a space cable system and work cooperatively, the thrust of the middle arch and the reverse thrust of the tail tilting stay arch bridge tower are balanced with each other, unbalanced internal force of the support is eliminated, and the novel three-fork bridge has the advantages of being attractive in appearance, convenient to traffic, large in spanning capacity, good in durability and the like.
本发明提出了一种三叶玫瑰线形钢管混凝土飞燕式斜拉拱桥及其施工方法，该拱桥针对三岔河地形，依据三叶玫瑰线图形，采用火工煨弯工艺，将钢管弯曲为三叶玫瑰线形飞燕式斜拉拱肋，悬吊三岔形桥面，从而形成三叶玫瑰线形钢管混凝土飞燕式斜拉拱桥。在拱脚之间设置拉索，在三叶玫瑰线形空间拱肋之间设置拱肋间拉索，形成自平衡结构体系，浮运拖拉过河，将三叶玫瑰线形飞燕式斜拉拱肋平稳落位于拱桥基础之上，在三叶玫瑰线形飞燕式斜拉拱肋上设置主拱吊索和尾部斜拉索，悬吊拼装三岔形桥面，施工方便。拱脚拉索、拱肋间拉索、主拱吊索和尾部斜拉索构成空间缆索体系，协同工作，中间拱的推力和尾部翘起斜拉拱形桥塔的反向推力互相平衡，消除了支座不平衡内力，新型三岔桥具有造型漂亮，交通便捷，跨越能力大和耐久性好等优点。
