Method for installing ultra-long steel structure corridor
The invention is suitable for the technical field of corridor installation, and provides an ultra-long steel structure corridor installation method which comprises the following specific operation steps: S1, a combined type crossing steel truss is provided with five sections, and three lifting sections of a middle large-span unit and non-lifting sections of cantilever structure units on the two sides are formed; s2, construction of a non-lifting section; s3, a hydraulic lifting system is arranged, wherein the hydraulic lifting system is mainly composed of a bearing steel strand, a hydraulic lifter, a pump source system and a sensing detection and computer synchronous control system set; s4, construction of a lifting section; s5, a hoisting process; according to the method, hydraulic multi-section lifting and hoisting are adopted, the high-altitude operation amount is reduced to be small, in addition, the overall hydraulic lifting operation time is short, the installation period can be shortened, meanwhile, the lifting sections are spliced into corresponding different shapes, in this way, butt joint of the lifting sections is facilitated, and the welding quality, the assembly precision and the detection precision are better and more excellent.
本发明适用于连廊安装技术领域，提供了一种超长钢结构连廊安装方法，具体操作步骤如下：S1、组合式穿层钢桁架设置有5段，并形成中部大跨度单元三段提升段和两侧悬挑结构单元非提升段；S2、非提升段施工；S3、液压提升系统布置，液压提升系统主要由承重钢绞线、液压提升器、泵源系统、传感检测及计算机同步控制系统组；S4、提升段施工；S5、吊装流程；S6、拆除临时措施，该方法采用液压多段提升吊装，将高空作业量降至较少，加之液压整体提升作业时间较短，能够缩短的安装工期，同时每个提升段拼装对应的不同的形状，这样便于提升段的对接，使焊接质量和装配精度及检测精度更好优秀。
