真空辅助压浆技术在后张预应力梁中的应用

摘要

Combining with the Pavilion of Arts and Sports of Newly-built City Experimental Primary School at some development zone,the paper illustrates the construction craft procedure of the vacuum auxiliary pressure grouting in projects,sums up its advantages,and points out the engi-neering practice proves that the craft can effectively ensure the grouting quality of the prestressed concrete beam channels.%结合某开发区新城实验小学文体馆工程实例，对工程采用的真空辅助压浆技术的施工工艺流程进行了阐述，归纳总结了真空辅助压浆的优点，并通过工程实践证明：该工艺有效地保证了预应力混凝土梁孔道的灌浆质量。
