[0002] Concrete spray curing is to spray water mist evenly on the concrete surface to keep the concrete moist and achieve the curing effect. By continuously spraying water mist, the concrete surface is prevented from drying, cracking and shrinking due to rapid water loss. Appropriate spray curing helps the cement hydration reaction, thereby improving the strength and durability of concrete. Spray curing can lower the temperature of the concrete surface, reduce temperature differences, and prevent cracks caused by temperature changes.

However, the layout of too many spray pipes is not convenient and difficult, and many pipes are required. The pipeline layout of the concrete spray maintenance device is not flexible enough, and it is not convenient to adjust the spray density and spray area after the layout is completed.
