[0002] Highway construction refers to the various engineering activities carried out when building, maintaining or renovating a highway, aiming to ensure the safety, durability and smooth traffic of the highway. After the highway construction is completed, the road surface needs to be regularly maintained and serviced to extend its service life and ensure traffic safety and comfort. Since the highway base contains a concrete layer, the concrete pavement needs to be watered and maintained after the concrete is poured.

[0003] When watering, the existing maintenance device generally uses a sprinkler truck to water along the concrete pavement. However, different highways have different road widths during construction. The existing sprinkler truck has a limited watering range. When the road surface is too wide, the sprinkler truck is required to repeatedly sprinkle water along the road surface. When the road surface is narrow, the watering range will be too wide, resulting in a certain waste of water resources, which makes the sprinkler truck have certain limitations in road maintenance.

[0004] In view of the above-mentioned related technologies, the inventor believes that the sprinkler truck has the defect of being inconvenient to adjust the watering range when maintaining the road surface. Therefore, a road surface maintenance device for highway construction is proposed to solve the above-mentioned problem. Utility Model Content
