1前言随着钢筋混凝土储存库的大量建设,工程现场经常发现钢筋混凝土筒仓内壁不同位置有明显的磨损差异,尤其是筒仓侧壁卸料口内侧局部区域被剧烈磨蚀,钢筋不同程度外露,甚至有仓壁大片掉落缺损和钢筋掉落的情况,这给筒仓结构的正常使用和工厂安全生产带来严重事故隐患。最近几年,此类磨损问题愈来愈多、愈来愈严重,参见库内壁磨损照片(图1)。 1 Introduction With the massive construction of reinforced concrete storage, the site often found significant differences in wear between different positions on the inner wall of reinforced concrete silos, in particular, the inner part of the discharge side of the silo was drastically abraded, exposed to varying degrees, There are even large warehouse wall defects and falling steel bar, which gives the normal use of the silo structure and safety accidents in the factory. In recent years, such wear problems more and more, more and more serious, see photos of wall wear (Figure 1).
