摘要
介绍了传统后张预应力现浇箱梁压浆存在的局限性,运用真空辅助压浆施工技术,使压浆工艺更加完善合理,消除了由于预应力管道压浆不饱满或钢绞线腐蚀造成的质量隐患。
This article introduces the limitation of traditional prestressed cast-in-place box girder grouting, suggests to use vacuum-assisted grouting to better grouting technique so as to eliminate the quality problems caused by not well-stacked prestressed pipe grouting or steel strand corruption.
