湿喷混凝土在隧道支护施工中的应用

Application of wet-spraying concrete in tunnel support construction

以某大长隧道初期支护施工中使用的机械手湿喷混凝土施工为例,分别从原材料质量要求、施工关键工序控制、确保施工质量措施等方面进行了介绍,以确保隧道初期支护效果、提高隧道施工安全性和施工环境,确保隧道工程效益。

Taking the manipulator wet-spraying concrete construction in the super-long tunnel preliminary support construction as an example,the paper respectively introduces the raw material quality requirement,critical construction procedure control and guaranteeing construction quality measures,with a view to guarantee the preliminary tunnel support effect,to improve the tunnel construction safety and construction environment,and to ensure the tunnel engineering efficiency as well.
