[0002] Concrete pavement is generally composed of four parts: roadbed, base layer, cushion layer and surface layer. The main material of the surface layer is concrete, which is generally required to be wear-resistant, flat, non-slip and strong. During the construction of concrete roads, sprinkler maintenance equipment is needed to sprinkle water on the concrete road surface to prevent dust from flying and improve the maintenance of the road.

When facing some concrete pavements with a smaller road width, the excessive length of the spray assembly causes a portion of the maintenance water to not be sprayed onto the road surface, resulting in waste and poor use effect.
