摘要 传统小箱梁预制采用普通钢模板,在组装模板时需要人力与机械配合,限制了施工速度。以预制桥梁技术为支撑,建立自动化更高的移动液压钢模板流水线预制技术,钢模可通过轨道系统实现快速转移、安装,提高箱梁预制效率。以G312南京城区改扩建项目为例,主要介绍移动液压钢模板在小箱梁预制施工中的应用,总结该模板使用过程中的特点,分析其在现代化箱梁预制场中的适用性。 The common steel formwork used in the traditional box girder prefabrication requires coordination of manpower and machinery during the assembly process,which limits the construction efficiency.With the support of prefabricated bridge technology,a higher automatic assembly line based on moving hydraulic steel formwork and prefabrication technology is established.The formwork can be quickly transferred and installed through the rail system,which can improve the prefabrication efficiency of box girder.The example of the reconstruction and extension project of Nanjing urban area is taken in this paper to discusse mainly the application of moving hydraulic steel formwork in the precast construction of small box girder and to analyze its function and applicability in the precast construction of modern box girder.
