1. Carry water reducing agent
Water reducing agent is a kind of concrete admixture, which can reduce the amount of water used for mixing while maintaining the collapse of concrete. It can be carried with the car and can adjust the concrete well. However, when participating in the water reducing agent, you must remember that there are people in the laboratory of Ueno station. Otherwise, the concrete quality is not enough, and the driver must bear the consequences.
2. Return to the factory to check the amount of water in the water tank
Every time you get off the train and return to the station, please check the amount of water in the water tank of the small concrete mixer. In case of emergency, the water tank can be filled at any time.
3. Check the concrete quality before delivery
The quality of each concrete reel may vary depending on the material. When leaving the concrete after installation, be sure to check the slump of the concrete in the storage tank and the ease of use of the concrete, and pay attention to the early setting of the concrete and the layered settlement of the concrete.
4. Reduce vehicle driving time
The transportation distance of concrete is usually less than 30 km in diameter. Before leaving the car, please plan the traffic conditions of roads and vehicles, and try to reduce the time of small concrete mixer on the road.
5. Give priority to unloading to reduce losses
If unloading is caused by human or non resistance factors for a long time, the condition of concrete in small concrete mixing tanks shall always be checked. Once it is found that the concrete begins to set. Unload immediately after reporting to the person in charge to prevent the whole packing box from being scrapped.
Secondly, the self feeding mixing conveyor needs to be cleaned at any time.
1. Wash at any time
After each unloading, use an oil tanker with a water gun to flush the water inlet, blades, inlet, water tank and the corners of the water tank to prevent concrete accumulation and difficult to clean after condensation. stand up.
2. Clean the tanker thoroughly after shutdown
After the feeding, mixing and conveying all-in-one machine is delivered every day, add more than 1m3 of fresh water to the water tank, and quickly rotate the water tank for cleaning. Qualified companies can also participate in the stone in tanks, and the effect will be better.
