Wet spray machinery as a main equipment of spray anchor support operations, Can be widely used in mine roadway, railway and highway tunnels, water conservancy culverts, the underground works, high-rise building foundation pit, military engineering and other construction, survey shows that its large-scale application in the country, began in Menghua railway construction. According to Mengxi Huazhong Railway Co., Ltd., a senior engineer introduced, at least more than 10 wet spray robot manufacturers to participate in the construction of Menghua railway tunnel, the whole line have been into the wet spray robot more than 200 units.

Compared to the traditional dry spray machine operations, wet spray robot operation can greatly reduce the dust concentration of the outside of machine and the nozzle, can effectively eliminate the harm to the health of workers.
More importantly, the use of wet spray robot operation, concrete rebound rate canbe reduced to about 15 percent, thus greatly improving the conctruction efficiency, and due to the ash is easy to control, can greatly improve the quality of shotcrete, the wet spray robot liberates manpower and reduces the amount of labor, also save costs. According to the labor force,  the labor of seven or eight individuals of artificial guns switch to large-scale wet spray robot only three people will be able to complete. "Said an experienced wet spray operator.
It is these advantages that have contributed to the rapid spread of wet spray robots in the country in recent years.
