Concrete shotcrete structure:
1. Jetting machine: It is mainly composed of hopper, mixing device, discharge elbow, gas path system, rotor, reducer and other parts. The motor drives the rotor to rotate through the reducer. Load the stirred material into the rotor, send it out of the elbow through the gas pipeline in the gas system, and then pass the mixture through the feeding pipe, the assistant of the auxiliary air pipeline in the air system Nozzle, spray to the receiving surface.
2. Cement slurry mixer: It is mainly composed of motor, gearbox, water tank, upper mixing bucket, lower mixing bucket, water tank control valve, and upper mixing bucket discharge valve. The cement slurry agitator is a double barrel type. After the first bucket is stirred, the first bucket is put into the lower bucket for preparation. After the upper bucket is stirred again, the mud pump is started, so that the work can be performed continuously.
3. Squeeze type cement slurry pump: It is mainly composed of motor, gearbox, pump casing, eccentric wheel frame, rubber hose, pipe joint and so on. This pump is a positive displacement pump, which does not require irrigation and drainage, and has strong self-priming capacity.
4. Mixing device: This mixing device is composed of left and right spiral mixing assembly and mud input device. Connected to the spiral mixing assembly is a delivery pipe and a spray gun.
