后张预应力混凝土孔道真空压浆施工技术

Construction technique of post-tensioned prestressed concrete duct vacuum prepackaged

真空压浆是后张预应力混凝土结构施工中的一项新技术,已经越来越广泛地应用于工程实践中。结合工程实例,从材料要求、浆体配制、机具准备、试压、压浆、清理等方面详细介绍了真空压浆施工工艺,并重点阐述了施工过程中的质量控制要点,可供类似工程参考。

Vacuum prepackaged is a new technique in construction of post-tensioned prestressed concrete. It has been broadly applied to the practical engineering. According to engineering practice, it introduces the vacuum prepackaged crafts of construction from pass material request, configuration mud, machine preparation, trypress, prepackaged, clearance. Quality control is discussed in the process of construction, which will provide the reference for similar engineering.
