Description

Technical Field

[0001] The utility model relates to a film covering and maintaining device, in particular to a film covering and maintaining device for cement pavement construction, belonging to the technical field of pavement construction. Background Art

[0002] The more commonly used maintenance method for cement pavements now is to cover the concrete structure or components with a film. After the initial setting of the concrete and before the final setting, the concrete curing film is manually laid to ensure that the curing film is tightly bonded to the surface of the cement road, promoting the hydration effect of the cement road and playing a significant role in preventing cracking and moisturizing during the maintenance process of the cement road.

[0003] In the Chinese patent application disclosure specification CN214939090U, a cement pavement maintenance device is disclosed. The base is moved along the direction of the film laying on the cement pavement, and the drive motor is started and the water spraying device is turned on. During the movement of the base, the water spraying device first waters and maintains the pavement where the film is not laid. The drive motor drives the film-laying roller located at the end of the vehicle body to rotate, and the film on the film-laying roller gradually moves toward the ground, which not only realizes the watering and maintenance of the cement pavement but also quickly lays and covers the film. The watering and film-laying maintenance are seamlessly connected, which effectively reduces the workload of construction workers and greatly improves the maintenance efficiency of the cement pavement.

[0004] Although the above patent solution can lay the curing film, since the film-laying roller is rotatably connected to the base, it is very troublesome to replace the film-laying roller. Workers need to spend more time to operate it. Especially in large-scale construction, the complicated replacement process will significantly affect the overall construction progress and reduce construction efficiency.

[0005] Therefore, a film covering and curing device for cement pavement construction is proposed. Utility Model Content
