During the construction process of the dry shotcrete machine, pipe blocking often occurs, causing delays in the construction period. Now Xiaobian will help you analyze the cause, find out the countermeasures, and solve your worries!
The possible reasons are:
1. The bone diameter is too large;
2. Insufficient air supply of dry shotcrete machine air compressor
3. The moisture content of the dry mix is too high;
4. The conveying air pressure is too low.
Corresponding measures:
1. The diameter of the sprayed aggregate should not exceed the specified parameter size. If the pipe blockage has occurred, stop the machine, close the air valve, remove the pipe from the elbow, open the gas valve, and blow out the material;
2. The dry shotcrete machine requires the use of an air compressor greater than 10 cubic meters per hour;
3. Stop the dry shotcrete machine and close the air valve. If the discharge elbow is blocked, open the pipeline and clean the pipe head and the material cavity
Stop the motor and air supply line of the dry shotcrete machine. If the rotor is blocked, open the air inlet pipe and the upper air pipe, and clean the rotor cavity with a brush.
