What are the precautions for shotcrete construction in the Reliance Shotcrete? Henan Hao Li spraying machine manufacturers to analyze the construction of shotcreting shotcrete shotcrete construction precautions.
1. When blasting concrete, air is blown first, and the sprayed surface is flushed with high-pressure water, and then the shotcreting machine is started to spray. The working pressure of the spraying machine is generally guaranteed to have about 0.1Mpa at the nozzle. Once the pipe is plugged, the air is stopped immediately. The water pressure at the nozzle is 0.1Mpa greater than the air pressure, but the pressure is required to be stable.
2. The thickness of the reinforced concrete is designed to be 60mm. It requires a one-time survival. The spray should be uniform and should not be too thick or too thin. The injection sequence should be divided into segments and bottom-up. The injection port and the injection surface should be as vertical as possible, the distance between 0.7 and 1.0 m, and the rebound rate should not exceed 25%.
3, set up another person at the same time as spraying, using aluminum alloy scraping ruler leveling, control the flatness of the wall surface, reduce the amount of plastering work.
4. In the process of spraying concrete, it is necessary to promptly check the surface of the sprayed concrete for looseness, cracking, falling, slipping, etc. If it occurs, it shall be promptly eradicated and re-injected.
5, spraying machine operators should wear goggles to prevent stone rebound and wounding. At the same time, we must do a good job of protective work in accordance with the requirements of work at height
