湿喷钢纤维混凝土支护在工程中的应用

Application of wet-spraying steel-fiber concrete lining in underground construction

本文介绍湿喷钢纤维混凝土支护在桐柏抽水蓄能电站地下厂房中的应用,包括“湿喷法”喷射钢纤维混凝土的力学性能指标、材料选择、配合比设计、现场试验、施工工艺等。

Wet-spraying steel-fiber concrete is more and more used in the lining of underground project, especially in the underground powerhouse of pumped-storage power station. This scheme guarantees the application of wet-spraying steel-fiber concrete in the lining of underground powerhouse of TongBai pumped-storage power station, including the mechanical properties, the selection of materials, matching ratio design, the experiments, and construction, etc..
