钢管拱拱脚预埋件精确定位施工技术

Construction technology of precise positioning of embedded parts of steel pipe arch

交通建设质量是国家建设实力的重要体现。近年来,随着科技的进步,越来越多先进技术运用到桥梁施工中。钢管混凝土拱桥在目前桥梁施工中最常见,钢管拱施工简单方便。建成后拱桥承载能力强,外型美观。因此,钢管拱在桥梁施工中很受欢迎。文章围绕钢管拱展开讨论,重点阐述拱脚预埋件施工,介绍施工工艺并阐述关键部位施工注意事项,对相关单位改进自身施工技术起到一定的借鉴作用。

Traffic construction quality is the important embodiment of national construction strength.With the progress of science and technology,more and more advanced technology used in bridge construction in recent years.CFST arch bridge is the most common.After completion,the arch bridge has strong bearing capacity and beautiful appearance.So steel pipe arch is very popular in steel tube arch bridge construction.This paper discusses the construction of steel pipe arches,focusing on the construction of arch foot embedded parts,introducing the construction process and elaborating the key points of construction,which will provide a reference for related units to improve their own construction technology.
