非标整孔简支箱梁支架现浇施工技术

Simply supported box girder cast-scaffold construction technology of non-standard whole hole

以京沪高速铁路京杭运河特大桥工程为例,介绍了非标整孔简支箱梁支架现浇施工技术,包括基础处理、模板安装、混凝土浇筑、预应力施工、压浆等环节的具体工艺及操作步骤,对特殊条件下支架现浇施工具有一定指导意义。

Taking Jing-Hang cannel bridge engineering on Beijing-Shanghai highway as an example, it introduces the simply supported box girder cast-scaffold construction technology of non-standard whole hole, including foundation treatment, template installation, concrete grouting, pres-tressed construction, mud jacking and other specific technologies and operation steps, which have certain guiding meaning for cast-scaffold construction under special condition.
