The invention provides a steel-bar net enclosure for a high-water-content material packed column, and relates to the technical field of underground supporting. The steel-bar net enclosure comprises a cylindrical steel-bar mesh, and circular steel hoops are fixed on the periphery of the steel-bar mesh at intervals. According to the steel-bar net enclosure, after the packed column is provided with a filled bag filled with solidifiable mixed liquor, the packed column can replace a wood crib, a masonry column and the like. The steel-bar net enclosure is low in cost and convenient to construct, is built mechanically, has high early-stage bearing capability and large final supporting resistance, has the advantages of being simple in process and high in degree of mechanization, expanding a ventilation section and the like, and is suitable for underground temporary or permanent supporting and others.
