Support-free section-by-section arching method for arch ribs of steel tube arch bridge
The invention discloses a steel tube arch bridge arch rib bracket-free section-by-section arch forming method which comprises the following steps: S1, hoisting each arch section to a mounting position, and temporarily consolidating two arch sections which are symmetrically arranged in the transverse bridge direction to form an arch rib unit Gi; s2, two adjacent arch rib units Gi are hinged in sequence; s3, a lifting device is connected with the arch rib unit Gi, meanwhile, a sliding support is arranged at the rear end of the arch rib unit Gi and the rear end of the arch rib unit Gi + 1, and a pushing device is arranged at the rear end of the arch rib unit Gi + 1; s4, the rear end of the arch rib unit Gi is lifted to the designed height by the lifting device, and the rear end of the arch rib unit Gi + 1 is synchronously pushed by the pushing device; s5, the hinged positions of the arch rib units Gi and the arch rib units Gi + 1 are welded and fixed; and S6, the lifting device is moved to the hinged position of the next arch rib unit, and the steps S3 to S5 are repeated till the arch rib is formed. The construction difficulty and risk and the construction cost of the arching stage can be reduced, and the method is suitable for arching construction of the large-rise and large-span arch bridge.
本发明公开了一种钢管拱桥拱肋无支架逐段成拱方法，包括以下步骤：S1、将各拱节吊装至安装位置，将横桥向对称设置的两个拱节临时固结形成一个拱肋单元Gi；S2、依次将相邻两个拱肋单元Gi之间铰接；S3、将提升装置与拱肋单元Gi连接，同时在拱肋单元Gi和拱肋单元Gi+1的后端设置所述滑动支座，在拱肋单元Gi+1的后端设置顶推装置；S4、由所述提升装置提升拱肋单元Gi的后端至设计高度，由所述顶推装置同步顶推拱肋单元Gi+1的后端；S5、将拱肋单元Gi与拱肋单元Gi+1的铰接处焊接固定；S6、移动所述提升装置至下一拱肋单元铰接处，重复步骤S3至S5，直至拱肋成型。本发明能够降低施工难度、风险以及成拱阶段的施工成本，适用于大矢高大跨度拱桥成拱施工。
