本文通过对明矾石无收缩自流灌浆料在设备基础二次浇灌层上的使用情况 ,对明矾石无收缩自流灌浆料的材料配比、施工方法进行了说明。本文认为在普通灌浆料难以施工、难以保证工程质量的一次浇灌层上 ,明矾石无收缩自流灌浆具有广泛的使用价值
This paper describes the material proportion and construction method of alum-free non-shrinkage gravity grouting material through the use of alum-free non-shrinkage gravity grouting material on the secondary-irrigation layer of equipment foundation. This paper considers that alunite non-shrinkage gravity grouting has a wide range of application value on a single layer of water that is difficult to apply to ordinary grouting materials and is difficult to guarantee project quality.
