后张预应力小箱梁的预制施工技术分析

Analysis on precast construction technology of post-tensioned pre-stress small box girder

结合工作实践,对后张预应力小箱梁的预制施工技术,从预制施工技术的流程、张拉预应力筋、张拉预应力程序、孔道压浆等几方面进行了论述,以提高后张预应力预制施工技术水平,确保小箱梁质量。

Combining with working practice and the precast construction technology of posttensioned prestress, discussed from precast construc tion technology process, posttensioned prestress, posttensioned prestress program, duct grouting and other aspects, in order to improve the precast construction technology level of posttensioned prestress, ensured the quality of small box girder.
