Description

Technical Field

[0001] The utility model relates to the technical field of road maintenance, in particular to a road and bridge pavement maintenance device. Background Technique

[0002] The concrete pavement of road and bridge projects needs to be watered regularly. The reason why concrete can gradually harden and increase strength is the result of the hydration of cement, and the hydration of cement requires certain temperature and humidity conditions. Regular watering during the maintenance process is to artificially create a suitable humidity environment to promote the normal hydration reaction of cement. During the hardening process of concrete, if the surface moisture evaporates too fast, it will cause the surface to dry, and then cracks may occur. Regular watering can keep the surface of the concrete moist and prevent cracks caused by drying. After retrieval, the publication number is (202122260973.7), which discloses a concrete pavement maintenance device for road and bridge projects, including tracks arranged on the opposite edges of the road surface. A base is arranged on the tracks. A guide wheel is arranged at the lower end of the base, and a water tank and a maintenance mechanism are arranged at the upper end of the base. The maintenance mechanism includes a lifting column and a water pump, and a water outlet pipe is arranged on the lifting column.
