Construction method of half-through steel tube arch bridge
The invention relates to a half-through steel tube arch bridge construction method, and belongs to the technical field of steel structure arch bridge construction. The construction method comprises the following steps that main towers are installed on the two sides of the design position of a bridge, cable cranes are installed on the main towers, and the cable cranes and the main towers are of a hanging buckle combined structural form; a main arch is installed between the two main towers, the main arch is formed by splicing a plurality of sections of arch ribs, each section of arch rib is hoisted and transported through a hoisting tool of a cable crane, and installation of the first section of arch rib is completed; the cantilever anchor beams are arranged at the buckling points of the arch ribs, the distance between the buckling cables is larger than the width of the cross section of the arch ribs, the cable crane and the cantilever anchor beams are adopted for hoisting and transporting the other segments of the arch ribs, installation of the other segments of the arch ribs is completed, and cross brace installation is conducted between the arch ribs. The cantilever anchor beams are arranged at the buckling points of the arch ribs, and the arch ribs are lifted by being attached to the arch backs of the installed segment arch ribs, so that the main arch is more convenient to install, and the construction method of the whole arch bridge is simpler.
本申请涉及一种中承式钢管拱桥施工方法，属于钢结构拱桥施工技术领域。该施工方法包括以下步骤:在桥梁设计位置的两侧进行主塔安装，并在主塔上进行缆索吊安装，其中，缆索吊和主塔采用吊扣合一的结构形式；在两个主塔之间进行主拱安装，主拱由多节段拱肋拼装而成，采用缆索吊的吊具对每节段拱肋进行吊装运输，完成第一节段拱肋的安装；在拱肋扣点设置悬挑锚梁，使扣索间距大于拱肋截面宽度的方式，采用缆索吊和悬挑锚梁对其余节段拱肋进行吊装运输，完成其余节段拱肋的安装，并在拱肋之间进行横撑安装。本申请通过在拱肋扣点设置悬挑锚梁，拱肋贴着已安节段拱肋的拱背进行吊运，从而使得主拱的安装更方便，以使得整个拱桥的施工方法更简单。
