Description

Technical Field

[0001] The utility model belongs to the technical field of roadbed maintenance, in particular to a spraying device used for road maintenance. Background Art

[0002] Spray maintenance in road subgrade construction refers to the process of regularly spraying water or other curing fluids onto the surface of the subgrade materials during the construction of the subgrade. The purpose is: appropriate moisture can increase the bonding force between soil particles, which helps to improve the compaction effect of the subgrade; in a dry environment, the subgrade material is prone to cracking due to water loss, and spraying can prevent this from happening; during the construction process, water spraying can suppress dust flying, improve the working environment of the construction site, and is also beneficial to the protection of the surrounding environment; in some cases, spray maintenance can also be used in conjunction with other chemical stabilizers to speed up the curing process of the subgrade material. Traditional road maintenance work usually relies on manual operations, such as manual watering or manual spraying of curing fluids. This method has some obvious disadvantages, such as:

[0003] Manual maintenance requires a large amount of human resources, especially in hot or cold weather conditions. The labor intensity of workers is extremely high, which can easily lead to health problems. Manual operation is slow and cannot meet the needs of large-scale or rapid maintenance. Due to the subjectivity and inconsistency of manual operation, the maintenance effect is often difficult to meet the expected standards.

[0004] To this end, we provide a sprinkler device for road maintenance to solve the above problems. Utility Model Content
