The weather is getting colder and colder, and shotcrete machine construction may encounter various problems, so it is more necessary to do a good job in maintenance and repair of the shotcrete machine. It is recommended to do anti-rust treatment of the shotcrete machine in advance.
Gunite Machine should strictly follow safe operating procedures, which requires every gunite operator to master this knowledge and strengthen their professional skills.
1. Protective equipment needs to be worn before spraying.
2. Check whether the equipment is normal. If there is no abnormality, start the equipment with no load and test machine for inspection.
3. Rinse and clean the required surfaces, especially the top or sides. Prevent it from falling off or collapsing at any time during spraying.
4. When the shotcrete machine is operating, a shotcrete commander is required to reasonably schedule each work station to complete the operation.
5. If the slurry accidentally enters the eyes or contacts the skin during spray grouting, it should be treated with clean water in time.
6. If any accident occurs during shotcrete construction, the machine must be shut down in time. The operation can only continue after the accident is eliminated.
7. During concrete spraying operations, it is strictly forbidden to stand in front of the nozzle.
8. When the work is stopped, the nozzle cannot be pointed at a place where there are people, so as to prevent dirt from entering the person's body.
9. When shutting down, you should first stop feeding, then turn off the motor and stop supplying compressed air.
10. After the operation, all the mixture in the bin and the conveying hose should be sprayed out, the nozzles should be removed and cleaned, and the concrete materials and debris adhering to the inside and outside of the machine body should be removed. At the same time, the feeding pipe should be cleaned and the seal should be relaxed.
Extend the service life of the shotcrete machine：
1. It is necessary to strengthen the daily routine of Shotcrete Machine equipment to prevent false maintenance and eliminate missed maintenance. Strengthen the daily inspection of shotcrete machine equipment. The inspection results should be recorded in detail, including not only previous records of shotcrete machines and replacement of shotcrete machine accessories, but also records of daily usage and workload, so as to be more timely and accurate. Analyze the hidden dangers of shotcrete machine failure.
2. Before using the shotcrete machine, it is necessary to first strengthen the technical training of the operators and strictly implement the operating procedures.
3. An often-overlooked issue that needs special attention is the impact of environmental factors on the service life of the shotcrete machine. Most of the shotcrete machine equipment operates in relatively harsh environments. The operation often changes due to changes in geological conditions, so its performance will also be affected by the temperature, humidity, geology and other conditions of the working site.
