Newly developed wet type concrete spraying system by ZZHZ
Wet type concrete spraying system is newly developed tunnel equipment these two years. They have been totally put in market after two years’ testing and modification.
The wet type concrete spraying system is widely used in the underground projects, geotechnical engineering projects and municipal engineering projects. With the concrete pump and free mechanical arm as the main parts of the machine, it can spray the concrete to from the supporting layer in the tunnel by compressing the air.
