[0047] The specific embodiments of the present invention are described in detail below in conjunction with the round pipe culvert wiping tool of the present invention.

[0048] like Figures 1 to 8 As shown, this embodiment discloses a circular pipe culvert smearing tool, including a mold body 1, a smear plate 2 and a hand handle 6.

[0049] The mold body 1 includes a first side plate 11, a mold convex plate 13 and a second side plate 12. The first side plate 11 contacts the surface of one circular culvert, and the second side plate 12 contacts the surface of another circular culvert. The mold convex plate 13 is arranged between the first side plate 11 and the second side plate 12 and is directly opposite to the gaps between the two circular culverts. A mold cavity is formed between the mold convex plate 13 and the two circular culverts 7. Figure 8 As shown, the mold cavity is directly opposite the area to be coated.

[0050] The smear plate 2 is arranged inside the mold cavity, and a smear cavity is formed between the smear plate 2 and the two circular culverts. The smear cavity is suitable for controlling the thickness of the smear strip 8 formed by the smear plate 2 applying mortar to the gap between the two circular culverts.

[0051] The hand grip 6 is arranged outside the mold body 1 to facilitate holding by hand.

[0052] The above-mentioned circular culvert tape smearing tool saves labor costs, has high efficiency, avoids the problem of uneven tape thickness on site and inability to form in one step, and provides a strong guarantee for the quality of engineering construction. The first side plate 11, the mold convex plate 13 and the second side plate 12 are bent integrally. Because the smear plate 2 is set inside the mold cavity, when mortar is applied, the first side plate 11 contacts the surface of one circular culvert, and the second side plate 12 contacts the surface of another circular culvert. At this time, the mortar is applied by the smear plate 2. The thickness of the tape 8 is determined by the position of the smear plate 2. Therefore, the use of this tool can realize the control of the thickness of the tape 8, so that the thickness of the formed tape 8 is more uniform.

[0053] It should be noted that the mold body 1 in this embodiment is made of a stainless steel plate. According to the curvature of the circular culvert, a slightly curved steel plate is processed and made, which is bent to both sides (the first side plate 11 and the second side plate 12). The bent surface is in contact with the circular culvert. At the same time, according to the thickness of the mortar, a stainless steel plate (applying plate 2) is welded inside the mold convex plate 13 to maintain the height and flatness control during the smearing process. That is, the first side plate 11, the second side plate 12 and the applicator plate 2 are respectively set to arc plates, so that the first side plate 11 can better fit the circular culvert, the second side plate 12 can better fit another circular culvert, and the smearing strip formed after the applicator plate 2 applies the mortar is arc-shaped.

[0054] In some embodiments, the smear plate 2 is fixed inside the mold cavity by welding, and the welding position of the smear plate 2 inside the mold cavity can be adjusted according to different needs. The specific installation process is: bend the stainless steel plate into a specific shape, connect the movable shaft with the smear plate 2, and finally weld the smear plate 2 into the mold cavity.

[0055] As a replaceable embodiment, the circular pipe culvert smearing tool further includes an adjustment structure 3, one end of the adjustment structure 3 is connected to the smear plate 2 and the other end is connected to the inner wall of the mold convex plate 13, and the adjustment structure 3 is suitable for adjusting the height position of the smear plate 2 in the mold cavity. The adjustment structure 3 is a telescopic rod 31. In this embodiment, the smear plate 2 is not fixed inside the mold cavity, but is adjusted in height by the telescopic rod 31, thereby adjusting the thickness of the smear cavity, so that the device can meet the formation of smearing tapes of various thicknesses.

[0056] At present, when a trowel is used to apply mortar to the gap between two circular culverts at the joint, the mortar needs to be poured into the gap between the two circular culverts each time before the mortar can be applied. In the process of applying the mortar, the mortar needs to be poured and applied multiple times, which is time-consuming, labor-intensive and very inconvenient. In order to solve this technical problem, in some embodiments, a slurry feeding structure 4 is provided at the front end of the mold body 1, and the slurry feeding structure 4 is suitable for conveying the mortar to the coating cavity, so that the device can realize both mortar conveying and mortar coating, and the mortar feeding and coating are combined, so that the generation of the smearing belt is very convenient.

[0057] More specifically, the slurry feeding structure 4 includes a slurry feeding box 41. The slurry feeding box 41 is arranged at the front end of the mold body 1, and a slurry feeding port 42 is arranged on the slurry feeding box 41, and the interior of the slurry feeding box 41 is connected to the coating cavity. A rotating shaft 44 is arranged at the slurry feeding port 42, and the rotating shaft 44 is rotatably arranged on the slurry feeding box 41. A rotating plate 43 suitable for controlling the opening and closing of the slurry feeding port 42 is connected to the rotating shaft 44, and a spring 45 is arranged between the rotating plate 43 and the side wall of the slurry feeding box 41. In this embodiment, the slurry feeding structure 4 is arranged to facilitate timely filling according to the amount of mortar, and the slurry feeding port is arranged in a movable manner. When the mortar moves to the position of the slurry feeding port 42, the mortar will squeeze the rotating plate 43 to rotate, and then the mortar enters from the slurry feeding port 42, and then the mortar enters the coating cavity through the slurry feeding box 41, so as to realize the transportation of the mortar.

[0058] In some embodiments, a coating structure 5 is also provided inside the mold cavity, and the coating structure 5 is suitable for coating the formed smear tape, so that the device integrates the transportation, application and coating of mortar, and there is no need for additional manual coating of the formed smear tape, which greatly reduces the amount of manual labor.

[0059] More specifically, the coating structure 5 includes a smooth roller 51 and a rotating hand wheel 53. The smooth roller 51 is rotatably set on the mold convex plate 13, one end of the smooth roller 51 extends out of the mold convex plate 13, and a curing film 52 is wrapped around the smooth roller 51. The smooth roller 51 with the curing film arranged near the slurry inlet has the effect of compacting the mortar and performing one-time curing. The rotating hand wheel 53 is connected to the end of the smooth roller 51 extending out of the mold convex plate 13. In this embodiment, the smooth roller 51 is flush with the smear plate 2 in the height direction, and then when the mold body 1 moves, friction is generated between the formed smearing belt and the curing film 52 on the smooth roller 51, and the curing film 52 is released onto the formed smearing belt under the drive of the friction force, thereby completing the coating of the smearing belt.

[0060] On the other hand, when the curing film cannot be released well, the curing film 52 can be released by manually rotating the hand wheel 53, which is very convenient.

[0061] The construction process of the utility model is as follows:

[0062] After the installation of the circular culvert is completed and the concrete pouring of the base is completed, the range of the smear tape at the interface of the circular culvert is roughened and moistened, and the circular culvert smear tape tool is used to fill the qualified mortar into the circular culvert smear tape tool. The front end of the circular culvert smear tape tool (the position of the slurry inlet structure 4) is facing upward, and the rear end is facing downward, and it is moved from bottom to top along the gap between the two circular culverts. The mortar entering the smear structure 4 will fall into the coating cavity under the coating plate 2. The coating plate 2 will apply and compact the mortar to form a smear tape. When the smear tape moves to the position of the smooth roller 51, it is compacted by the smooth roller 51, and drives the smooth roller 51 to rotate, and the curing film 52 is released onto the smear tape. After completion, after reaching final setting, the mold is removed in time.

[0063] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
