Steel truss arch bridge arch rib and main beam mounting method
The invention provides a steel truss arch bridge arch rib and main beam mounting method, relates to the technical field of bridge construction, and aims to realize mounting of an arch rib and a main beam at the same time and save the construction period and construction equipment. The method comprises the following steps that firstly, two side spans of the steel truss arch bridge are constructed, and the two side spans are symmetrically constructed; secondly, an arch climbing crane is installed on each side span; thirdly, the two sets of arch climbing cranes gradually hoist the steel arch rod pieces from the side spans to the middle spans of the two sets of arch climbing cranes, and installation is completed till the steel arch rod pieces are folded; and fourthly, the two sets of arch climbing cranes symmetrically construct suspenders and main beams from the middle span to the side spans. According to the method of the invention, the arch rib and the main beam can be simultaneously mounted by adopting the arch climbing crane, so that one machine has two purposes, construction equipment is saved, and the construction period is shortened.
本公开提供了一种钢桁架拱桥拱肋及主梁安装方法，涉及桥梁施工技术领域，能够同时实现拱肋和主梁安装，又能节约工期和施工设备。包括以下步骤：步骤一、施工钢桁架拱桥的两个边跨，两个边跨对称施工；步骤二、在每个边跨安装爬拱吊机；步骤三、两组爬拱吊机从各自边跨向中跨逐步吊装钢拱杆件并完成安装，直至钢拱杆件合拢；步骤四、两组爬拱吊机从中跨向边跨对称施工吊杆、主梁。本发明的实施例采用爬拱吊机能同时实现拱肋和主梁的安装，实现了“一机两用”，节省了施工设备和施工工期。
