高位现浇、落梁就位技术在施工中的应用

Application of High Position Cast-in-place and Drop-beam In-Place Technology in Construction

近年来,我国的城际铁路建设发展迅速,在城区建设项目周边环境越来越复杂,建筑物、既有线、管线、高架桥等制约现场施工,箱梁施工方法不局限于预制架设、现浇施工,复杂情况下高位现浇、落梁就位技术成为一种新的选择。本文以京雄城际铁路黄固特大桥为例,阐述了高位现浇、落梁就位技术在箱梁施工中的应用。

In recent years,the construction of inter-city railways in China has developed rapidly.The surrounding environment of urban construction projects is becoming more and more complex.Buildings,existing lines,pipelines,viaducts,etc.restrict construction on site.Box girder construction methods are not limited to prefabricated erections and cast-in-place construction.In the complex case,highposition cast-in-place and drop-beam in-place technology has become a new choice.Taking the Huanggute Bridge of Jingxiong Intercity Railway as an example,this paper expounds the application of high position cast-in-place and drop-beam in-place technology in box girder construction.
