某特大桥在预应力工程施工前,在配制高性能灌浆材料的基础上,通过两种灌浆工艺试验,对孔道灌浆的饱满度和密实度进行了研究,指出孔道灌浆的关键技术在于高性能水泥浆体的配置技术。
Based on the preparation of high-performance grouting material before the construction of prestressed concrete bridge, two special grouting techniques were used to study the plumpness and compactness of grouting in a special bridge. The key technology of grouting was pointed out that high performance cement Slurry configuration technology.
