[0002] A pier is a load-bearing structure used to support the upper structure in civil engineering. While piers are mostly circular in cross-section, they can also be elliptical, square, curved, or parabolic. They are crucial components of highway bridges, railway bridges, pedestrian bridges, overpasses, ramps, and flyovers. After construction, bridge piers require curing to fully hydrate the cement, accelerate the hardening of the concrete, and prevent damage such as abnormal shrinkage and cracking.

[0003] At present, the most common maintenance method for bridge piers is watering. During the watering process, in order to retain water in the piers, they need to be covered with a film to achieve a better maintenance effect. However, the existing devices for covering bridge piers with maintenance films generally have problems with unstable film coating and inability to adapt to piers of different heights. For example, a film covering device disclosed in Chinese Patent No. 210975558 has the problem of unstable film coating, and the film coating operation is easily interfered with by the outside world; in addition, a film covering device disclosed in Chinese Patent No. 211446611 cannot be adapted to piers of different heights, and its scope of application is relatively small.

[0004] Based on this, it is necessary to propose a new type of film covering device, which can realize rapid and automatic covering of the film, greatly improve construction efficiency, ensure covering quality, and has good versatility and adaptability. Utility Model Content

[0011] Furthermore, the surface of the laminating drum is coated with a film.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The utility model realizes rapid and automatic covering of the film through the lifting device and the coating roller, which greatly improves the construction efficiency compared with the traditional manual covering method; the sliding connection between the coating roller and the supporting frame, and the assistance of the positioning device enable the film to fit tightly to the surface of the bridge pier, avoiding the generation of bubbles and wrinkles, thereby ensuring the covering quality; the device can adapt to bridge piers of different heights and diameters by adjusting the positions of the lifting device and the coating roller, thereby improving the versatility and adaptability of the device.
