摘要
通过具体工程实例,分析了真空辅助压浆技术的基本原理,提出了真空辅助压浆浆体材料要求及技术指标,详细介绍了真空辅助压浆技术的施工工艺及其质量控制要点,指出真空辅助压浆技术必将在后张法预应力混凝土结构中得到广泛应用。
Combined with practical work basis principle of vacuum assistance injection technique is analyzed as well as the mortar materials and technical indexes. Construction technology and key points for quality control are introduced in detail. Author points out that vacuum assistance injection technique will be widely applied in post-tensioned prstrssed concrete structures.
