Line type control construction method for large-span ultra-wide steel box girder self-anchored suspension bridge
The invention relates to the technical field of bridge engineering construction, and discloses a large-span ultra-wide steel box girder self-anchored suspension bridge linear control construction method which comprises the following steps: establishing an incremental launching construction numerical model, performing drawing and structural design according to stress condition analysis data, and planning an installation process at the same time; segmenting the steel box girder according to a drawing, and processing the steel box girder into segments in a factory; transporting the manufactured sections of the steel box girder to a construction site; pushing equipment is installed, and a control system is connected and debugged; the steel box girder sections are hoisted to an assembling platform through a gantry crane to be assembled; and after the steel box girder sections are accepted and accepted to be qualified, the steel box girder sections are pushed to proper positions by adopting a walking type pushing method according to the installation process, and the girder assembling and pushing steps are repeated until all the steel girders are pushed. The line type control construction method for the large-span ultra-wide steel box girder self-anchored suspension bridge can adapt to the line type change of the girder body, the horizontal force of the bridge pier is effectively controlled, the construction efficiency is high, the construction quality is high, and very high safety is achieved.
本发明涉及桥梁工程施工技术领域，公开了一种大跨度超宽钢箱梁自锚式悬索桥线型控制施工方法，包括如下步骤：建立顶推施工数值模型，根据受力情况分析数据进行图纸绘制和结构设计，同时计划安装流程；按照图纸进行钢箱梁的节段划分，在工厂加工制作成节段；将制作好的钢箱梁的节段运输至施工现场；安装顶推设备，连接控制系统并调试；将钢箱梁节段通过龙门吊吊装至拼装平台组装；钢箱梁节段验收合格后按照安装流程采用步履式顶推法顶推至合适位置，重复主梁组装、顶推步骤，至所有钢主梁顶推完成。本发明大跨度超宽钢箱梁自锚式悬索桥线型控制施工方法，能够适应梁体线形的变化，有效控制桥墩水平力，施工效率快，施工质量高，具有很高的安全性。
