跨铁路既有线转体桥施工技术

Construction Technology of Swing Bridge over Existing Railway Line

当今,桥梁工程已经成为交通运输工程建设中的重点内容,随着桥梁工程建设数量和规模的增加,桥梁工程施工技术也在不断的发展。尤其是在跨铁路既有线转体桥梁工程的施工过程中,先进的桥梁施工技术更是发挥着不可或缺的作用。为保障跨铁路既有线转体桥梁工程施工质量,提升施工安全性,以葫芦岛经济开发区特大桥工程项目为例,对该施工技术的应用进行分析。文章主要分析了转体系统的组成、转体桥主要的施工工艺、技术要点和各项影响因素的控制措施。希望通过本次的研究,为跨铁路既有线转体桥的施工提供相应参考,让转体桥施工技术在此类工程中发挥出更加显著的优势。

In today's world,bridge engineering has become an important part of transportation engineering construction.With the increase in the number and scale of bridge engineering construction,bridge engineering construction technology has also achieved continuous development.Especially in the construction process of the existing railway turn bridge project across the railway,advanced bridge construction technology is playing an indispensable role.In order to ensure the construction quality and safety of the existing transrail swivel bridge project,this article takes Huludao Economic Development Zone Extra Large Bridge Project as an example to analyze the application of the construction technology.The article mainly analyzes the composition of the swivel system>the main construction technology of the swivel bridge,the technical points and the control measures of various influencing factors.It is hoped that through this study,the construction of the swivel bridge across the railway can be provided with reference,so that the swivel bridge construction technology can play a more significant advantage in such projects.
