We know Sandblasting pipe It is a sandblasting high-pressure hose used for wet sandblasting and dry sandblasting in construction. Today, we talked about the problems that must be paid attention to in the whole process of the construction of the sandblasting pipe spewing concrete project. The quality of the sandblasting pipe spewing concrete immediately endangers the construction quality, so it is necessary to adopt appropriate construction methods.

1. The concrete sandblasting pipe sprayed the hockey before the first treatment, the anchor bolt was loose, the anchor plate did not stick to the cliff wall net pocket, and after getting rid of the data connection again, the partition was cut. Tighten the nuts and loosen them so that they are close to the anchor plate on the surface of the rock stratum. If the anchor is not working, make up again for the lack of mesh structure sponge mat mesh in the fully developed area.

2. The front wind water is used to wash the face of the high-pressure sprayer, and the human body is firmly integrated to ensure jet spraying. The raw material of hand operated concrete water cement ratio water jet spraying is not milky white, does not drift, and the surface with gloss is suitable. Before painting, use high pressure jet aircraft feng shui to clean the human body and closely combine anxiety to ensure jet aircraft spraying. Shotcrete blasting construction site

3. The concrete spraying steps were extensively carried out by two people. During the whole process of project construction, they should cooperate closely, find problems and treat them immediately. Anchor shotcreting, grasp the perspective and spacing of the gushing, and ensure that the sprinkler is vertical to the cliff wall. In general, the order of gushing is from top to bottom, from the back to the front, fill the large pit and fill the concave ground for leveling, and then carry out a spraying according to the actual operation.

4. Strict implementation shall be carried out in accordance with the provisions of "Three year end, cable, four no". That is, shot blasting is used to remove the rust. When the hard road sprayer is sprayed, two ductile raw materials are used to help remove the rust; According to the excellent standard size, there is no water, no stumbles, no skirts, no tendons.

5. Spraying machine to remove dirt inside the equipment, so as to avoid the pipe just before starting. The feeding station shall estimate the inner cavity feeding pipe. After my estimate, all sewage treatment and cleaning of the internal and external units shall be carried out. The actual operation sequence of the shotcrete machine: 1 Output power: water - air - transmission - feeding - surging. 2. Stop: stop feeding --- power off --- air stop --- no water. In special cases, such as when a power failure occurs.

6. The gas spraying machine must be a fixed nozzle to avoid the nozzle shaking to death. Solve the problem of blocking the pipe, or increase the working pressure of the gas to solve the problem of air, switch on and off the power supply, stop the air and open the electric air valve to the outside to make up the leakage,?? Then, close the air circuit of the safety relief valve, and the power engineering will deliver the solution.

7. Before anchoring and shotcreting of concrete sandblasting pipe, all kinds of high pressure pipes must be firmly connected to Fengshui, and 10 # fine iron wire must be added for connection to avoid death due to disconnection.

8. When applying it, spray the fountain, spice and paint, and erect a back fountain.

9. Implement the anchor spraying of damp objects: the anchor sprays spices and adds appropriate water to make the mixed hands hopefully loose and disperse, and the mouth discharges ash.

10. Improve safety protection Sandblasting pipe When painting, be sure to wear a dust mask. Dust producing equipment should not be used. All kinds of sensitive and reliable anti pollution equipment should be used. The construction team shall maintain all kinds of anti fouling equipment. If damaged, it must be repaired immediately to ensure all normal applications.

11. Be sure to remove the obstacles on the spot and cover the cables, power lines, pipelines, lighting fixtures and other equipment on the spot during maintenance.

12. It is strictly forbidden to probe into all parts of the human body to solve the blockage at the feeding port of the shotcrete machine.

13. To solve the problem of sand blasting pipe blockage, you must gradually increase the working pressure, and it is forbidden to point from the nozzle to the staff.

14. Do a good job of safety protection at the construction site.

15. At the end of the day, the raw materials with rebound shall be removed by bolting and shotcreting, the skirting line shall be repaired by hand pick, and the bulge part shall be flattened to eliminate the rebound of the feeding pipeline on the machine equipment.

16. One person is responsible for the safety construction inspection of anchor shotcreting, and the top wall live stone shall be properly treated. If the treatment is not applied immediately, it is necessary to ensure the safety of the project before construction.

17. It is forbidden for everyone to work or stay in the light wind area rationally. The person in charge of the construction team must bring portable tile detection instruments. The concentration of vapor and carbon dioxide is 1%, and you must immediately terminate the actual operation. The operation will resume when the concentration value decreases below 1%.
