At present, wet mix shotcrete machine is domestic and foreign anchor-spray support equipment with better overall performance such as reducing dust, reducing rebound, and saving materials are available. Currently widely used in mines, culverts, tunnel, foundation pit support, hydraulic engineering protection.
Compared with dry mix shotcrete machine, wet mix tunnel shotcrete machine have below outstanding advantages, such as:
★Greatly reduces the concentration of dust on the side of the machine and outside the nozzle, eliminating the harm to the health of workers;
★Low rebound, when the dry spray, concrete rebound up to 15% -50%, using wet spray technology, the rebound rate can be reduced to 10%;
★In wet spraying, since the water-cement ratio is easy to control and the degree of hydration of concrete is high, the quality of shotcrete can be greatly improved and the homogeneity of the concrete can be improved. While dry spraying, the water-cement ratio of concrete is based on the experience of the sprayer. By visual observation to adjust, the quality of the concrete depends to a great extent on operator skills.
★High productivity.
