桥梁工程中箱梁支架搭设施工技术

Construction Technology of Box Girder Support in Bridge Engineering

箱梁在现代桥梁工程中比较常见,能够为路面提供更好的承载力,但是箱梁的现场施工却存在着一定的技术难度,需要加强控制管理。对桥梁工程中箱梁支架搭设施工技术进行研究,以实际工程项目为例,针对关键环节展开分析,以期不断提升桥梁工程技术应用水平。首先介绍了南通东方大道快速路高架项目工程概况,然后研究了其中的箱梁支架搭设施工技术,包括地基处理、搭设形式、技术要点、支架预压等方面。

Box girder is more common in modern bridge engineering and can provide better bearing capacity for the pavement.However,on-site construction of box girder has certain technical difficulties and needs to strengthen control and management.The construction technology of box girder support in bridge engineering is studied,and taking actual engineering projects as examples,the key links are analyzed,which is hoped that it can play a positive role in promoting and continuously improve application level of bridge engineering technology.Firstly,the general situation of Nantong Dongfang Avenue Expressway elevated project is introduced,and then the box girder support erection construction technology is studied,including foundation treatment,erection form,technical points,support preloading and so on.
