Technical Field

[0001] The utility model relates to the field of bridge construction equipment, in particular to a maintenance device for municipal road bridges. Background Art

[0002] After pouring concrete on a bridge, if the climate is hot and the air is dry and curing is not carried out in time, the moisture in the concrete will evaporate too quickly, resulting in dehydration. This will prevent the cement particles that have formed a gel from being fully hydrated and from being converted into stable crystals, leading to a lack of sufficient bonding strength. This will result in flaky or powdery shedding on the concrete surface, and at this time, it will need to be replenished with water.

[0003] In existing concrete curing, a film or geotextile is covered on the concrete and water is sprinkled on it to keep it moist and prevent the water from escaping too quickly and causing shrinkage cracks. In the existing technology, the unwinding action of the film or geotextile requires manual operation, and additional watering is required when laying the film, which makes the curing operation inconvenient.
