真空辅助压浆是一种代替传统压浆施工的新型施工工艺,可以增加浆体材料的密实度,避免管道内因压浆带入的水,防止预应力钢束的锈蚀,提高结构物使用寿命,是一种值得推广的压浆技术。黄河三桥中在实践中较好的应用了真空辅助压浆技术,为今后的工程提供了实践经验。 Vacuum-assisted grouting is a new type of construction process instead of traditional grouting construction, which can increase the density of the slurry material, prevent the water inside the pipeline from being squeezed into the grout, prevent the corrosion of prestressed steel strands and improve the service life of the structure, Is a worthy promotion grouting technology. Yellow River Bridge in practice, the better application of vacuum-assisted grouting technology for the future project has provided practical experience.
