Construction method of steel box tied arch bridge
The invention discloses a construction method of a steel box tied arch bridge. The construction method comprises the following construction steps of main beam support erection, main beam splicing, arch rib support erection, arch rib splicing, pull rod and suspender installation, pull rod tensioning, arch rib frame removal, arch rib support removal, suspender tensioning, main beam frame removal and main beam support removal. The splicing auxiliary device is used for splicing the main beam and the arch rib, the splicing precision of the main beam and the arch rib can be effectively guaranteed, and it is guaranteed that the structural stress meets the design requirement; the splicing auxiliary device can adapt to main beams and arch ribs with different section forms, and the engineering application range is wide. The problems of arch rib closure, arch rib frame separation, main beam frame separation and the like in the construction process of the steel box tied arch bridge can be effectively solved.
本发明公开了一种钢箱系杆拱桥施工方法，包括如下施工步骤：搭设主梁支架、主梁拼接、搭设拱肋支架、拱肋拼接、拉杆、吊杆安装、拉杆张拉、拱肋脱架、拱肋支架拆除、吊杆张拉、主梁脱架、主梁支架拆除。采用拼接辅助装置进行主梁及拱肋的拼接作业，可有效保证主梁以及拱肋的拼接精度，保证结构受力满足设计要求；拼接辅助装置可适应不同截面形式的主梁、拱肋，工程适用范围广。本发明可以有效地解决钢箱系杆拱桥施工过程中存在的拱肋合龙、拱肋脱架、主梁脱架等问题。
