When using the construction Explosion Proof Shotcrete Machine in winter, special attention needs to be paid to the following aspects to ensure the safety, performance and reliability of the equipment:
1. Concrete mixing ratio: Adjust the mixing ratio of concrete to ensure that it can maintain appropriate fluidity in low temperature environments. Cold temperatures can cause concrete to set, so the proportions of cement, stone and water need to be adjusted.
2. Freeze-thaw cycle: Consider the impact of the freeze-thaw cycle and use a concrete formula with good cold resistance to prevent freeze-thaw damage in the winter environment.
3. Preheating of Shotcrete Machine equipment: Properly preheat the construction concrete shotcrete machine before work to ensure that the engine, hydraulic system and other key components can quickly reach the optimal working temperature during work.
4.Gunite Machine Heating System: If the gunite machine is equipped with a heating system, make sure it is working properly. This helps prevent concrete or water from freezing in delivery pipes and nozzles.
5. Hydraulic system: Low temperature will affect the fluidity of hydraulic oil. Use hydraulic oil suitable for low-temperature environments and ensure that the hydraulic system is maintained at the appropriate operating temperature.
6. Shotcrete Machine cleaning and maintenance: Clean the equipment regularly to prevent snow, ice or frozen materials from accumulating in key areas. Ensure equipment is in a good state of maintenance to reduce the risk of failure in cold conditions.
7. Nozzle and conveying system: Check and keep the nozzle and conveying system smooth to ensure that the concrete can be sprayed evenly and stably to prevent the nozzle from freezing.
8. Safe operation: Pay special attention to safety when working on snow-covered ground. Make sure access roads to the construction site are clear and clear to prevent slips and other accidents.
9. Environmental monitoring: Monitor weather and environmental conditions, especially temperature, humidity and wind speed. In extreme cold conditions, extra precautions need to be taken.
10. Operator warmth: Provide sufficient thermal insulation equipment for the operator of the shotcrete machine, including cold-proof clothing, gloves, hats, etc., to ensure that the operator can stay comfortable in cold weather.
By taking these aspects into consideration, it is possible to ensure that the construction concrete shotcrete machine can operate safely and efficiently in harsh winter weather conditions.
