Gas hood method sprayed concrete construction method
The invention relates to a construction method for spraying concrete by a gas hood method, which solves the problems that the existing concrete material is directly exposed in normal-pressure air after being sprayed out, and part of the concrete material always falls off after rebounding due to diffusion and collision, so that the material is wasted, construction wastes are generated, the construction cost is increased and the environment is polluted. The method comprises the following steps: S1, designing a mix proportion of sprayed concrete; s2, treating a sprayed surface; s3, a sprayed concrete thickness control mark is installed; s4, selecting a concrete sprayer; s5, creating a closed gas hood on the sprayed surface; s6, concrete is sprayed in the closed gas hood; s7, maintenance of the sprayed concrete; and S8, quality inspection and acceptance of the sprayed concrete.
气罩法喷射混凝土施工方法，解决现在混凝土材料在喷出后直接暴露在常压空气中，始终存在部分混凝土材料因扩散和碰撞反弹回来后发生掉落现象，导致材料浪费并产生建筑垃圾，不仅增加施工成本，且污染环境的问题。其包括如下步骤：S1，喷射混凝土配合比设计；S2，受喷面处理；S3，安装喷射混凝土厚度控制标识；S4，混凝土喷射机选择；S5，受喷面营造封闭气罩；S6，封闭气罩内喷射混凝土；S7，喷射混凝土的养护；S8，喷射混凝土的质量检查和验收。
