Construction method of bridge camber arch rib
The invention discloses a construction method of a bridge camber arch rib. The construction method comprises the following steps of prefabricating a plurality of arch rib sections, arranging a plurality of first bailey beams in the bridge direction at intervals, fixing one end of each first bailey beam to the bridge, and enabling the other end of each first bailey beam to extend out of the bridge, arranging a second bailey beam on the first bailey beam extending out of the bridge, and building a steel framework on the second bailey beam, and taking the steel framework as a support, and hoisting the arch rib sections to form the outwards-inclined arch rib. The method for building an island on a river channel is eliminated through the construction mode, the construction efficiency is higher, the construction period can be greatly shortened, the construction method is not affected by a river in the construction process, and the method is suitable for the field of bridge construction.
本发明公开了一种桥梁外倾拱肋的施工方法，包括以下步骤：预制多个拱肋节段；顺桥向间隔设置多个第一贝雷梁，各第一贝雷梁的一端固定在桥梁上，各第一贝雷梁的另一端伸出桥梁；在伸出桥梁的第一贝雷梁上设置第二贝雷梁，在第二贝雷梁上搭建钢构架；以钢构架为支撑，吊装拱肋节段形成外倾拱肋，通过这种施工方式杜绝了在河道上筑岛的方法，施工效率更高，能够大大缩短工期，而且在施工过程中不会受到河流的影响，本发明适用于桥梁施工领域。
