Small shotcrete machine for doing concrete pools is a equipment used for shotcrete. It has the characteristics of reasonable structure, stable performance, convenient operation and maintenance, and long service life. Small shotcrete machine for doing concrete pools is widely used in mines, tunnels, culverts, subways, and slope supports. Construction work of sprayed concrete for roadway of protection, hydropower engineering, underground engineering and coal mine high gas mine. The small shotcrete machine for concrete pools uses compressed air to transport the concrete mixture in a certain proportion through the pipeline and spray it on the sprayed surface at a high speed to harden, thereby forming a concrete supporting layer. In recent years, sprayed concrete technology has been widely used in construction, railway tunnel construction, mine shaft construction, slope reinforcement and other fields with its simple technology, effect, economic cost and fast construction speed. Precautions for the use of small shotcrete machine for concrete pools:
1. Once the conveying pipe is blocked, the switch can be switched to the manual position, only the air compressor is turned on, the joint in front of the pump head is removed, and then the spraying is blocked down to make the wind pressure generate reverse pressure, thereby reducing the conveying The remaining slurry in the tube is blown out. After the joint is installed, normal operation can start; when the pump pressure is insufficient during work, the booster stator bolt can be adjusted, or the booster rubber sleeve and the booster screw can be replaced
2. Workers should wear safety helmets, protective glasses, work clothes and other labor protection products during sandblasting; it is strictly forbidden to start idling when there is no water or material in the hopper; if there is mortar after working for a long time If it overflows from the transmission part or finds abnormal noise, it should immediately stop for inspection, replace the mechanical seal, and carry out maintenance and repair to avoid greater damage to the equipment;
3. When spraying, the nozzle should be as perpendicular to the sprayed surface as possible, and the spraying distance can be adjusted according to the spraying effect; it should be sprayed evenly in layers and coordinated with the flattening process. When the wall is too dry or sprayed for too long, it will seriously affect the flattening effect. The intelligent operation of the operation should change the operating procedures and processes at any time; the mortar is too thick or the resistance of the machine is too large when the machine is running dry, which will easily cause the motor load to increase. If abnormal noise or pipe blockage occurs, you must stop the machine immediately for inspection and adjust the mortar consistency in the hopper.
