Dry Mix Electric Driven Gunite Machine Advanced Technology for
tunnel culvert
Gunite Machine
Prepare for startup Gunite Machine:
1. Check the connection of each line of the electronic control
system is firm and there is no leakage phenomenon.
2. Observe the oil mark and check whether the lubricating oil in
the reducer is sufficient.
3. Check whether the fastening of all parts of the machine is
correct and reliable.

Operation Method of Gunite Machine:
After the preparation work is finished, the mixing material can be
added to the machine. The machine operator should first open the
main valve, the valve of the upper air duct opens 1/3 circles, and
then adjust the air pressure of the lower air duct (to the cyclone)
to about 0.05-0.1 MPa (depending on the delivery distance). Then
the sprayer opens the nozzle valve and gives the wet rock surface.
At this time, the operator can start the machine and start
shotcreting. Now the working pressure is about 0.2-0.4 MPa.
According to the water-cement ratio of mixtures and the length of
conveying distance, after adjusting and determining the wind
pressure to the cyclone, the upper air pipe valve is opened again
until there is no more material leakage at the machine outlet.
