As people's awareness of environmental protection increases and the quality requirements for shotcrete increase, more and more wet shotcrete machines will be used. Let's talk about the understanding of wet shotcrete machine.
In recent years, some domestic units have also begun to develop several wet shotcrete machine, but the production scale has yet to be expanded. In summary, the main advantages of China Coal Wet Shotcrete Machine are:
(1) The dust concentration beside the machine and outside the nozzle is greatly reduced, and the harm to the health of workers is eliminated.
Dry coagulation shotcrete machine generally does not exceed the use of wet shotcrete machine, which can reach 10 cubic meters/h for manual operation, and up to 20 cubic meters/h for manipulator operation.
(3) Low resilience. When dry spraying, the rebound on coagulation can reach 15%-50%. Using wet spray technology, the rebound rate can be reduced to less than 10%.
(4) When wet spraying, because the water-cement ratio is easy to control and the concrete hydration degree is high, it can greatly improve the quality of sprayed concrete and improve the homogeneity of concrete. When dry spraying, the water-cement ratio of concrete is determined by the sprayer. According to experience and visual observation to adjust, the quality of concrete depends to a large extent on the correct operation of the robot.
