Efficient construction method for side span cast-in-place concrete beam of steel-concrete composite beam cable-stayed bridge
The invention discloses an efficient construction method for a side span cast-in-place concrete beam of a steel-concrete composite beam cable-stayed bridge, and relates to the field of cable-stayed bridge construction methods. The efficient construction method comprises the following steps that transition piers, permanent auxiliary piers and temporary auxiliary piers are constructed and built; constructing and erecting a full framing on a first span adjacent to a bridge head of the cable-stayed bridge or a second sub-span adjacent to a bridge tower; and the first span or the second span where the full framing is erected is subjected to cast-in-place to form a first section of main beam, the full framing is dismantled, the full framing is constructed and erected on the next first span or the second span adjacent to the first section of main beam till the last first span or the second span is subjected to cast-in-place to form the Nth section of main beam, and the full framing is dismantled. The span of the side span concrete beam in the construction period is effectively reduced by adding the temporary auxiliary piers, it is ensured that the side span concrete beam can adopt the sectional type continuous beam forming construction method, the use time of the full framing can be greatly shortened through the method, the utilization rate of the full framing is increased, the construction cost is reduced, and the construction period is shortened.
本发明公开一种钢混组合梁斜拉桥边跨现浇混凝土梁高效施工方法，涉及斜拉桥施工方法领域，包括以下步骤：施工建设过渡墩、永久辅助墩和临时辅助墩；在斜拉桥桥头相邻的第一跨或与桥塔相邻的第二分跨施工架设满堂支架；对架设满堂支架的第一跨或第二分跨现浇形成第一段主梁，拆除满堂支架，在第一段主梁相邻的下一个第一跨或第二分跨施工架设满堂支架，直至最后一个第一跨或第二分跨现浇形成第N段主梁，拆除满堂支架。通过增加临时辅助墩的方式有效减小施工期间边跨混凝土梁的跨径，确保边跨梁能够采用分段式连续成梁的施工方法，该方法可以使满堂支架大大缩短使用时间，提高了满堂支架的利用率，降低施工成本，缩短工期。
