本文针对后张预应力管道灌浆现场对制作浆液过程中加水计量不准确或随意加水增加浆液流动性的现状,设计了一款用于压浆施工现场的水胶比测试仪,该仪器可以实时测试现场拌制浆液的密度与水胶比,杜绝不合格浆液的使用,有利于保证预应力管道压浆施工质量。 This paper aims at the status quo of post-tensioned pre-stressed pipe grouting field to make inaccurate measurement of water addition or increase the fluidity of slurry at the time of making slurry, and designs a water-binder ratio tester for grouting construction site, which can be tested in real time. The density of the slurry mixed with the water-binder ratio at the site eliminates the use of unsuitable slurry and helps to ensure the construction quality of the prestressed pipeline.
