Three-section one-line rapid installation method for large-span pipe truss string structure
The invention relates to the technical field of large-span pipe truss string structure installation, in particular to a three-section one-line rapid installation method for a large-span pipe truss string structure. The method sequentially comprises the following steps that S1, the pipe truss is assembled on the ground in a sectional combination mode; S2, mounting operation of prestress inhaul cables and a plurality of inhaul cable supporting rods is conducted on a ground operation platform, the prestress inhaul cables are connected with the lower ends of all the inhaul cable supporting rods, and the prestress inhaul cables are unfolded on the ground operation platform to complete mounting; and S3, the inhaul cable supporting rods and the prestress inhaul cables are lifted to the preset positions together with the pipe truss through a hoisting machine, and the pipe truss is supported through a plurality of auxiliary supporting frames. According to the method, the high-altitude operationis reduced, the installation difficulty of the inhaul cable supporting rods and the prestress inhaul cables is lowered, and efficiency and safety are improved.
本发明涉及大跨度管桁架张弦结构安装技术领域的一种大跨度管桁架张弦结构三段一线快速安装方法，依次包括如下步骤：S1、在地面采用分段组合的方式拼装成一个管桁架；S2、在地面操作平台上进行预应力拉索和若干拉索撑杆的安装操作，预应力拉索连接所有拉索撑杆下端，并使得预应力拉索在地面操作平台上展开并完成安装；S3、利用起重机械，将拉索撑杆及预应力拉索随管桁架一同提升至预设的位置，并用若干辅助支撑架支撑管桁架。减少高空作业，降低拉索撑杆和预应力拉索的安装难度，提高效率和安全性。
