在后张法有粘结预应力砼结构中,为确保预应力筋不受腐蚀,同时保证结构混凝土与预应力筋共同工作,都要采用将水泥浆充满预留孔道和预应力的孔隙予以解决。因此,压浆的质量直接影响到构件的耐久性。用普通的压浆工艺就要花费大量的人力、物力来保证压浆质量。随着施工工艺的进步和革新,近几年逐渐发展起来的真空辅助压浆工艺,已在国内几座桥梁中应用,本文主 In the post-tension method with prestressed concrete structure, in order to ensure the prestressed tendons from corrosion, while ensuring the structural concrete and prestressed tendons work together, should be used to fill the pore water slurry and pre-stressed pore to be solved . Therefore, the quality of grouting has a direct impact on the durability of the component. With the ordinary mortar process will spend a lot of manpower and material resources to ensure the quality of grouting. With the progress of construction technology and innovation, vacuum assisted grouting technology that has been gradually developed in recent years has been applied in several domestic bridges.
