聚丙稀微纤维喷混凝土在隧道施工中的应用

Application of polypropylene tiny fiber shotcrete in tunnel construction

在喷混凝土中掺加一种新型材料———聚丙稀微纤维,是改善喷混凝土性能的一种有效方法。文章主要介绍了微纤维的性能及微纤维喷混凝土在隧道施工中的应用情况,以及微纤维喷混凝土施工技术在降低成本等方面的显著效果,值得广泛推广和应用。

To add a new material-polypropylene tiny fibers in shotcrete is an efficient way to improve its performance. This paper briefly introduces the characteristics of this kind of tiny fibers and their application in tunnel construction, pointing out that the effect of the technique of tiny fiber shotcrete in diminishing the construction cost is obvious and it is worthy to be widely adopted.
