Description

Technical Field

[0001] The invention relates to the technical field of road maintenance, and in particular to a maintenance device for construction roads. Background Art

[0002] After concrete pouring, if the climate is hot and the air is dry, if the concrete is not maintained in time, the water in the concrete will evaporate too quickly, resulting in dehydration, which will prevent the cement particles that have formed a gel from being fully hydrated and converted into stable crystals. The lack of sufficient bonding force will cause flakes or powders to fall off on the concrete surface. In addition, when the concrete does not yet have sufficient strength, the premature evaporation of water will also produce large shrinkage deformation and shrinkage cracks. Therefore, the maintenance in the initial stage after concrete pouring is very important. The concrete should be maintained immediately after final setting. The dry hard concrete should be maintained immediately after pouring. The existing maintenance device cannot clean the road surface and spray water evenly when in use. At the same time, the film needs to be pressed down manually with soil and stones to prevent the film from being blown away and losing its function.
