What are the operating procedures for concrete sprayer sprayers? Concrete sprayer, also known as concrete shotcreting machine, Henan Mu force sprayer manufacturers to introduce concrete sprayer sprayer operating procedures.
1. Spray mortar should use wet spray or wet spray, not dry spray.
2, before the first spray, should be knocked to ask the top, clearing the living. Before the first spraying and the second spraying, the sprayed surface must be flushed with wind and water. When the surrounding rock is not suitable for seeing water, the dust from the sprayed surface can be blown with the compressed air.
3. Before the blasting, the floating raft at the base of the two walls of the roadway shall be cleaned and the design requirements shall be met.
4. Prior to spraying, the arches, spandrels, and arches should be set at every 10 meters before pulling, and vertical lines should be drawn on the arch foundation line to strictly inject the double shots to ensure the spray thickness and flatness.
5. Prior to spraying, the equipment, tools, and other pipes and lines must be removed. If it cannot be removed, it must be covered and protected. After the injection is completed, the rebounds on equipment and other facilities must be cleaned.
6. When the height of the roadway is more than 3 meters, set up a work bench or use a robotic spray.
7. When there is no direct contact between jets and sprayers, special contact signals should be provided.
8. The sprayer should be equipped with two persons. One person is to hold a gun and one person assists and is responsible for observing the top plate and spraying conditions to ensure safety and quality of injection.
9, before the injection, the jet equipment and wind, water pipes, cables shall be subject to a comprehensive inspection and test operation. If it is found that the friction plate is seriously worn, the compression screw rod fails, and the nozzle water is not normal. It is strictly prohibited to deal with the fault.
10. Personnel engaged in spraying and loading materials should wear dust masks, long latex gloves, glasses or other labor protection products.
11. Prepare the recycling of rebounds before spraying. Make full use of the rebounds after spraying.
12. Before blowing the machine down, it is necessary to blow the material inside the machine. After shutting down, the spray equipment and its surroundings must be cleaned, and the pipelines must be neatly arranged.
13. Before spraying, the middle and waist points must be covered with yellow mud or other materials, and they must be promptly exposed after spraying.
14. Concrete spraying sequence: open the air first, then open the water, and finally send the material to the point; end the sequence: stop the material first, wait until the material in the tank is sprayed, and then stop the power in the blackout.
15. For different types of concrete jets, operate strictly according to their instructions.
16. When the material is fed into the concrete sprayer, it must be sieved and the feeding should be continuous and uniform. When the machinery is in normal operation, sufficient stock must be kept in the hopper to ensure that the injection is even and continuous, and rebound is reduced.
17. The cement number used for shotcreting or shotcreting is generally not lower than No. 425, and cement that has expired and damped and agglomerated must not be used.
18. A special unloading yard should be set up for the tidal jet working face. The sand and stones added to the water must first be discharged to the stockyard and used only after 10 hours of infiltration.
19. Sewage shall not be used, acidic water with a PH value of less than 4 and no harmful impurities that affect the normal setting and hardening of cement.
