Technical Field

[0001] The invention belongs to the technical field of concrete curing, and specifically refers to a concrete winter curing device and a use method thereof. Background Art

[0002] Concrete winter maintenance refers to a series of technical measures to keep concrete warm, keep it moist and promote its strength development after pouring in cold seasons. Due to the low temperature in winter, the hydration reaction of concrete slows down. If proper maintenance is not carried out, it is easy to lead to insufficient strength development of concrete and increased internal stress, which will affect the overall project quality.

[0003] Among the traditional winter curing methods for concrete, steam curing is widely used due to its uniform heating and fast heating rate. Steam curing sprays high-temperature steam onto the concrete surface to increase the temperature and humidity around the concrete to promote its hydration reaction.

[0004] However, this method has certain defects in practical application. Since the water on the concrete surface evaporates quickly during steam curing, shrinkage cracks are easily formed on the concrete surface if the moisture retention measures are not appropriate. Summary of the invention

[0016] Step 1: After the concrete road is poured, the maintenance body drives to the top of the concrete road, the output end of the motor 1 rotates to drive the drive shaft to rotate, the drive shaft rotates to drive the wheels to rotate, the wheels rotate to drive the maintenance body to move forward, open the electronic valve, and the antifreeze in the antifreeze storage tank flows to the ultrasonic atomizer through the drip tube. The ultrasonic atomizer atomizes the antifreeze and mixes it with the airflow generated by the air pump and enters the air outlet pipe.

Steam curing can provide suitable temperature and humidity conditions for concrete, slow down the heat loss inside the concrete, and help the cement hydration reaction. At the same time, steam can also humidify, slow down the volatilization of water, further promote the hydration reaction of concrete, and improve the strength and durability of concrete. The lifting cylinder can adjust the height of the lifting chamber and is suitable for concrete pavements of different heights.

[0018] Step 3: Finally, start the booster pump, spray the water in the water tank through the atomizing nozzle and then blow it to the steam-treated concrete pavement through the fan, which can continuously provide the necessary moisture for the concrete, keep it moist, and help the concrete harden and increase its strength.

[0019] The beneficial effects achieved by the present invention using the above structure are as follows:

[0020] (1) By adjusting the height of the steam nozzle, the distribution of steam on the concrete surface can be optimized. When the nozzle is close to the concrete surface, the steam can act on the concrete more directly, reducing the loss of steam in the air, thereby improving the uniformity of curing.

[0021] (2) By adjusting the height of the steam nozzle, you can flexibly respond to different working conditions and ensure the best maintenance effect.

[0022] (3) After the antifreeze agent is atomized by the ultrasonic atomizer, it can be more evenly and finely covered on the concrete surface and come into more complete contact with the concrete, thereby improving the antifreeze effect.

[0023] (4) Steam curing can provide suitable temperature and humidity conditions for concrete, slow down the heat loss inside the concrete, and help the cement hydration reaction. At the same time, steam can also humidify, slow down the volatilization of water, further promote the hydration reaction of concrete, and improve the strength and durability of concrete.
