Section unit of super-large-span concrete-filled steel tube arch bridge and arch bridge
The invention particularly relates to a segment unit of a super-large-span concrete-filled steel tube arch bridge and the arch bridge. The segment unit comprises a main pipe and a branch pipe. The main pipe comprises an upper chord pipe and a lower chord pipe, the branch pipe comprises an inclined web pipe and a vertical web pipe, and the upper chord pipe and the lower chord pipe are both provided with connecting joints. The ratio of the compressive rigidity of the branch pipes to the flexural rigidity of the main pipe is smaller than or equal to 0.5, wherein the two ends of each segment unit are each an inclined web pipe and/or a vertical web pipe, and the corresponding ends of every two adjacent segment units are each an inclined web pipe and a vertical web pipe. The distance between tubular joints, located between every two adjacent segment units, of the inclined web pipes and the vertical web pipes is larger than the distance between tubular joints, located in the segment units, of the inclined web pipes and the vertical web pipes. The hoisting units are flexibly divided, and web pipes do not need to be additionally arranged, so that the steel consumption is reduced, the engineering cost is saved, the hoisting frequency is reduced under the same-level hoisting condition, and the construction period is shortened.
本发明特别涉及一种超大跨径钢管混凝土拱桥的节段单元及拱桥，节段单元包括主管和支管，所述主管包含上弦管和下弦管，所述支管包含斜腹管和竖腹管，所述上弦管和下弦管均设有连接接头，所述支管的抗压刚度与所述主管的抗弯刚度的比值≤0.5，所述节段单元的两端部分别为斜腹管和/或竖腹管，相邻两个所述节段单元的对应端部分别为斜腹管和竖腹管，所述斜腹管和竖腹管位于相邻两个所述节段单元间的相贯节点间距大于所述斜腹管和竖腹管位于所述节段单元内的相贯节点间距。吊装单元划分灵活，无需增设腹管，利于降低用钢量，节省工程成本，在同级别吊重情况下利于减少吊装次数，缩短施工工期。
