Description

Technical Field

[0001] The utility model relates to the technical field of water-retaining cloth spreading, in particular to a water-retaining cloth spreading device for highway bridge construction. Background Art

[0002] During the construction of highway bridges, it is necessary to lay concrete on the bridge deck to form a road surface to enhance the strength of the highway. After the concrete road surface is laid, it is necessary to lay a layer of water-retaining cloth on the road surface and sprinkle water on the water-retaining cloth. The existing water-retaining cloth spreading device often requires multiple people to operate the water-retaining cloth, and then sprinkle water after laying a layer of water-retaining cloth.

[0003] For example, a water-retaining cloth spreading device for highway bridge construction with publication number CN218492232U includes a water tank, both sides of the edge of one side of the bottom surface of the water tank are fixedly connected with support plates, the bottoms of the two support plates are connected to moving wheels for common rotation, the middle of one side of the two support plates are fixedly connected with water-retaining cloth roll support brackets, both sides of the middle of the bottom surface of the water tank are fixedly connected with connecting ears, and the bottoms of the corresponding sides of the two connecting ears are connected to two guide rollers for common rotation. The advantage of this utility model is that: water is sprayed downward toward the top surface of the water-retaining cloth through the first sprinkler pipe, and at the same time, the second sprinkler pipe is used to spray water synchronously to the bottom surface of the water-retaining cloth and the concrete surface, so that water can be sprayed before the water-retaining cloth is spread, so that the bonding effect can be improved when it is spread, and it can be prevented from being scraped off. Through the two guide rollers, the water-retaining cloth can be horizontally passed between the first sprinkler pipe and the second sprinkler pipe, so that both sides of the water-retaining cloth receive water evenly.

[0004] However, based on the working principle proposed in the above patent, the applicant believes that although the above device can make both sides of the water-retaining cloth receive water evenly and improve the adhesion effect to a certain extent, in actual use, the flattening roller of the above device does not have a compression adjustment function, and cannot adjust the degree of compression according to the specific conditions of the construction site, and cannot ensure that the cloth is always evenly compressed and covered.

[0005] Therefore, in view of the above problems, a water-retaining cloth spreading device for highway bridge construction is proposed. Utility Model Content
