| Abstract: | The causations of the problems occurred during the mechanized construction of the concrete lining for the surface protection of a channel， such as longitudinal cracks， irregular desiccation cracks， transverse penetrated cracks， construction cold joints， structural damage cracks under effect of external force， etc. are analyzed， and then an enclosed curing installation is self-developed. Thus， the cracks on the concrete lining of the channel are effectively restricted by the application of this installation. |

| Keywords: | large channel enclosed curing installation concrete crack anti-cracking measures |
