京沪高速铁路广阳梁场冬期施工技术

Winter Construction Technology at Guangyang Beam Fabricating Yard in Beijing-Shanghai High-speed Railway

以京沪高速铁路广阳梁场冬期制梁为例,详细介绍了制梁台座、存梁台座、钢筋加工区、搅拌站以及混凝土搅拌与浇筑保温措施,箱梁蒸汽养护温度控制技术和预应力孔道压浆养护方法。

Heat preservation measures which are used in the areas of beam fabricating and storage pedestals,reinforcing steel working and mixing plant,also are applied in the processing of concrete agitating and pouring are introduced detailedly.Meanwhile,temperature control techniques of steam curing in box girder and maintenance methods of prestressed duct grouting are equally recommended in this paper-a case study of Guangyang beam fabricating yard in Beijing-Shanghai high-speed railway.
