混凝土墙钢筋保护层的控制,按常规施工方法是绑扎水泥砂浆预制块。但该工序很麻烦,且费工费料。笔者从事工程建设监理时,曾采用一种新的工艺,收到较好的效果。即在钢筋与模板之间竖向插入钢管控制保护层,钢管下端压扁,钢管上端可焊一挂钩,以便挂于模板上, The control of the reinforced concrete layer of the concrete wall is according to the conventional construction method. But this process is cumbersome and costly. When the author engaged in engineering construction supervision, he used a new process and received good results. That is, the steel pipe is vertically inserted between the reinforcing steel and the template to control the protective layer, the lower end of the steel pipe is flattened, and a hook can be welded at the upper end of the steel pipe so as to be hung on the template.
