Cable-stayed bridge steel-concrete composite girder mounting method
According to the cable-stayed bridge steel-concrete composite girder installation method, the lifting station is innovatively installed near the main pier, in the actual installation process, the lifting station splits and lifts each section of steel-concrete composite girder to the bridge floor, and then the steel-concrete composite girder is installed on the bridge floor; and then on-site splicing is conducted on all components of the main beam through a full-rotation deck crane. Compared with the content introduced in the background technology, the installation method for the steel-concrete composite girder of the cable-stayed bridge has the advantages that large hoisting equipment such as a tower crane and a crawler crane does not need to be installed on the ground, and the problems that a traditional construction method is greatly limited by the geographical environment and space, and the economical efficiency of the large hoisting equipment is poor are solved; and the lifting station is arranged on the bridge floor, and each component of each section of the main beam is lifted on the bridge floor, so that compared with a lifting mode of traditional ground lifting equipment from bottom to top, the lifting station has the advantages of high lifting efficiency and short construction period, and has important guiding significance for later installation of the steel-concrete composite main beam of the cable-stayed bridge.
本发明提供了一种斜拉桥钢混叠合主梁安装方法，该斜拉桥钢混叠合主梁安装方法，创新性的在主墩附近安装提升站，在实际安装时，提升站将每节段钢混叠合主梁进行拆分吊运至桥面，之后通过全回转桥面吊机对主梁的各构件进行现场拼装。相较于背景技术介绍内容，该斜拉桥钢混叠合主梁安装方法，无需在地面上安装例如塔吊、履带吊一类的大型吊装设备，解决了传统施工方法受地理环境、空间限制大以及大型起重设备经济性差的难题；并且提升站设置在桥面上，吊装各节段主梁的各构件时是在桥面上进行吊运，相比于传统地面吊装设备由下而上的吊运方式，具有吊装效率高，施工周期短的优点，对以后斜拉桥钢混叠合主梁的安装具有重要的指导意义。
