As a crucial component of these bridge structures, the quality of the bridge tower concrete directly affects the bridge's service life and safety. However, bridge tower concrete is prone to temperature cracks during construction, and studies have shown that 80% of concrete cracks are caused by improper curing. Therefore, solving the problem of bridge tower concrete curing is particularly important. Currently, the main curing method involves covering the concrete surface with straw mats, burlap sacks, or other moisture-retaining materials and periodically watering it manually. This traditional curing method is not only inefficient but also relies on the subjective experience of construction workers, making it difficult to ensure the consistency of curing quality.

2. A method for intelligent curing of bridge tower concrete using the intelligent curing device for bridge tower concrete as described in claim 1, characterized in that, Includes the following steps: Step 1: Start the temperature measuring fiber (3-3), weather station (3-1) and temperature and humidity sensor (3-2), and collect data at a frequency of 30 minutes / time; Step 2: After acquiring multi-source data, the intelligent maintenance platform controls the temperature-controlled water tank (1) based on the measured data through the Internet of Things and remote control technology to adjust the temperature of the maintenance water. Step 3: After the water temperature is adjusted, start the automatic curtain pulling device (6-1) to unfold the curtain along the preset guide rail (6-2). After the automatic curtain pulling device (6-1) reaches the end point, it brakes and fits into the guide rail (6-2). The magnet at the edge of the upper curtain and the magnet on the platform are magnetically attracted to each other to form a closed environment. Then open the solenoid valve (1-2) of the temperature-controlled water tank and the solenoid valve (4-5) on the spray device (4) to transfer the curing water to the voltage regulator (4-4) on the spray device (4) and start the sprayer (4-1) for curing. Step 4: During the spray maintenance process, the system continuously monitors various data. After the data indicators return to the preset range, the solenoid valve (1-2) of the temperature control water tank and the solenoid valve (4-5) and sprayer (4-1) on the spray device (4) are closed, and the automatic curtain pulling device (6-1) is activated to cooperate with the roller shutter machine (6-3) to retract the curtain.
