What is the difference between artificial wet spray concrete and mechanical wet spray concrete?
Rebound material and dust on the spray of a great impact on the rebound of the stone easy to hurt the shooter, so the general wind pressure will not be very full, mechanical jet can completely avoid this problem, the wind pressure can make the dense layer
The efficiency of artificial injection is low, less than the robot spray fast; artificial spray angle is not the best, especially in the pouring arch, the nozzle is always tilted, the machine can be completely vertical, to achieve better spray;
A higher degree; artificial spray can not reach the site where the collapse is occurring, mechanical jet just deal with such dangerous situations, give full play to the advantages of spray
