Description

Concrete pavement maintenance device Technical Field The application relates to the technical field of pavement maintenance, in particular to a concrete pavement maintenance device. Background After the concrete pavement is poured and molded, water spraying maintenance is needed to ensure the strength of the subsequent concrete pavement, and meanwhile, the shrinkage cracking problem caused by the excessively fast evaporation of the water in the concrete pavement can be prevented. At present, when a concrete road is maintained, maintenance vehicles are generally adopted for maintenance, but the maintenance vehicles meet the condition that the road surface is narrower, such as a pavement, a park road and other sections, the maintenance is generally carried out by manually dragging a water pipe for spraying, or manually pushing a trolley for maintenance, a transverse water pipe is arranged below the trolley, a plurality of spray heads are arranged on the water pipe at intervals, and when the trolley is pushed, the spray heads are used for discharging water to maintain the road surface below. In the related art, the mode of dragging the water pipe to spray is high in labor intensity and low in efficiency, and the mode of maintaining through the trolley is adopted, because the length of the water pipe is fixed, when the road width is inconsistent with the width of the trolley, the trolley is required to be pushed back and forth, so that the efficiency is low, and when the trolley is pushed back and forth, the water spraying at the middle intersection part is excessive due to the fact that the road width is different.
