跨太榆路钢箱梁吊装施工技术研究

Research on Lifting Construction Technology of Steel Box Girder Across Taiyu Road

本文以太原武宿机场空港配套工程的高架桥施工为研究案例,通过对钢箱梁段的吊装施工技术和支架搭设过程中需要重点把控的要点进行阐述,此外,对施工过程中和施工完成后的钢箱梁吊装质量控制几个要点进行说明,这有利于避免桥梁吊装的施工过程出现一系列的质量问题和现场施工事故的发生,保障了现场施工人员的人身安全,减少因为施工问题导致的返修而带来的成本费用方面的增加,提高项目的经济效益。

Taking the viaduct construction of the auxiliary project of Taiyuan Wusu Airport as a case study,this paper expounds the lifting construction technology of steel box girder section and the key control points in the construction process of bracket erection,in addition,several key points in the lifting quality control of steel box girder during and after construction are explained,this is conducive to avoiding a series of quality problems and on-site construction accidents in the construction process of bridge hoisting,ensuring the personal safety of on-site construction personnel,reducing the increase in costs caused by repairs caused by construction problems,and improving the economic benefits of the project.
