喷射混凝土工艺是一种新型、特殊的施工工艺,主要用于地震、火灾后房屋修复处理,以及工程质量事故处理和老厂改建结构的加固。具有处理工艺简单,不用或少用模板,混凝土强度和粘结力强,耐久性、抗渗性好,可薄层加固,质量易于保证,施工速度快、成本低等优点。目前国内应用较多的是干法工艺,即将按一定比例配合搅拌 The shotcrete process is a new type of special construction process. It is mainly used for the repair and treatment of houses after earthquakes and fires, as well as the treatment of engineering quality accidents and the reinforcement of old factory remodeling structures. It has the advantages of simple treatment process, no or little use of template, strong concrete strength and adhesion, good durability, impermeability, thin layer reinforcement, easy quality assurance, fast construction speed and low cost. At present, most of the domestic applications are dry process, which will be mixed with a certain percentage
