桥梁预应力管道压浆施工质量控制技术及应用

Research and Application of Prestressed Pipeline Grouting Quality Control

文章从预应力管道压浆浆体材料源头质量和压浆施工实时监测两个方面介绍管道压浆施工质量控制技术以及工程应用。压浆浆体性能、尤其是泌水性能的提高是十分必要的。利用压浆施工记录仪监测灌浆压力、出浆压力、流量等施工工艺参数,可加强压浆施工过程的质量控制。

The paper analyzes and sums up the existing problems about post-prestressed grouting. It is necessary to improve the performance, especially the bleeding performance of slurry. Grouting automatic monitoring data recorder that is a kind of automatic monitoring system is applied in the highway bridge construction of prestressed duct grouting. The grouting pressure, slurry pressure and grouting flux acquired by the grouting automatic monitoring data recorder are used to analyze the actual situation of grouting process.
