[0024] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0025] Embodiment 1:

[0026] A water-locking curing roll for cement-stabilized crushed stone layers, such as Figure 1-2 As shown, it includes a reel 11 and a roll body 12 wound on the reel 11, the roll body 12 includes a water-absorbing pad layer 121 and a film layer 122 bonded to the surface of the water-absorbing pad layer 121, the water-absorbing pad layer 121 is a kind of cotton cloth layer and sponge layer, and has a thickness of 2-5 mm.

[0027] After the water-locking curing roll is laid on the cement-stabilized gravel layer, the water-absorbing cushion layer 121 and the membrane layer 122 perform multiple water-locking operations to achieve a better water-locking effect and increase the curing quality. At the same time, since the water-absorbing cushion layer 121 and the membrane layer 122 are connected together, they can be laid out at the same time, making laying simple and convenient, thereby reducing construction costs.

[0028] The embodiment also relates to a laying device suitable for laying the above-mentioned water-locking curing roll, such as Figure 3 As shown, it includes a mobile frame 2, the bottom of which is provided with walking wheels, the water-locking curing roll is rotatably installed on the mobile frame 2 through a reel 11, and the mobile frame 2 is driven by an external driving device. When laying the roll body 12, the free end of the roll body 12 is pressed by a pressure object such as a stone. Through the movement of the mobile frame 2, the automatic laying of the water-locking curing roll can be realized, reducing the intensity of manual laying.

[0029] After the maintenance work is completed, the laid roll 12 generally needs to be recycled. However, the fact is that the water-absorbing cushion layer 121 in the roll 12 often still absorbs a certain amount of water, which is not conducive to the winding and recycling of the roll 12.

[0030] To this end, the laying equipment also includes a water squeezing mechanism 3, which is installed on the movable frame 2 and located on the side of the water-locking curing roll, and includes a water squeezing roller 1 31 and a water squeezing roller 2 32. The water squeezing roller 1 31 and the water squeezing roller 2 32 are rotatably installed on the movable frame 2, and the water squeezing roller 2 32 is located above the water squeezing roller 1 31, and a squeezing space is formed between the two. In addition, a vertical mounting groove 1 21 is provided on the movable frame 2, and the axial end of the water squeezing roller 2 32 is limited in the vertical mounting groove 1 21.

[0031] When the maintenance work is completed and the roll 12 is recycled, first, one end of the roll 12 laid on the cement stabilized gravel layer is lifted and passed through the space between the squeezing roller 1 31 and the squeezing roller 2 32 and then rewound on the reel 11. The squeezing roller 2 32 presses the roll 12 between the squeezing roller 1 31 and the squeezing roller 2 32 onto the squeezing roller 1 31 under the action of its own gravity. At this time, the state of the roll 12 is shown in FIG. Figure 4As shown, the mobile frame 2 is then moved by an external driving device, and during the movement of the mobile frame 2, the reel 11 is rotated so that the reel 11 winds the roll body 12. During the winding process, the squeezing roller 1 31 and the squeezing roller 2 32 cooperate with each other to squeeze out the water absorbed by the roll body 12 as much as possible, so as to reasonably and effectively recover the roll body 12. Of course, the speed during winding should be appropriate to ensure that the roll body 12 will not become loose.

[0032] The reel 11 has a reel shaft, such as Figure 5 As shown, the reel shaft includes a handle docking portion 11-1 for connecting a handle. When rotating the reel 11, an external handle is connected to the handle docking portion 11-1, and the reel 11 is conveniently and easily rotated by the handle. The handle docking portion 11-1 can be a groove portion with a docking groove.

[0033] like Figure 3 As shown, the mobile frame 2 is also provided with a leveling mechanism; the leveling mechanism includes a leveling roller 5, and the mobile frame 2 is provided with a second vertical mounting groove 22, and the shaft end of the leveling roller is limited in the second vertical mounting groove 22 and can be raised and lowered in the second vertical mounting groove 22. This structural arrangement can flatten the roll body 12 when laying the curing roll, and can adaptively change the height of the leveling roller according to the leveling condition of the cement stabilized gravel layer, so that the roll body 12 can be laid more reasonably on the cement stabilized gravel layer.

[0034] Embodiment 2: During the winding recovery process, the water-absorbing cushion layer 121 may be attached with gravel. If not processed, not only will the obtained water-locking curing roll have bulging problems, but also the gravel may lift the water squeezing roller 2 32 in the squeezing space and affect the squeezing effect.

[0035] For this purpose, the paving equipment in the embodiment is also provided with a stone-splitting mechanism 4, such as Figure 6-7 As shown, the stone-sweeping mechanism 4 includes a dusting rod 41, a swing frame 42, a driving shaft 43 and a driving motor 44, wherein the dusting rod 41 is parallel to the water squeezing roller 31, both ends of the dusting rod 41 are respectively mounted on the swing frame 42 and are located within the wrapping angle of the winding body 12 when it is wound around the water squeezing roller 31, the swing frame 42 is fixedly connected to the driving shaft 43, the driving shaft 43 is rotatably mounted on the moving frame 2, the driving shaft 43 is parallel to the water squeezing roller 31, and the end of the driving shaft 43 is connected to the output shaft of the driving motor 44, and is rotated by the driving motor 44.

[0036] When the driving shaft 43 rotates, the swing frame 42 and the duster rod 41 on the swing frame 42 are driven to rotate around the driving shaft 43 as the central axis. During the rotation, the duster rod 41 causes the roll body 12 to jump up and down, thereby dusting off the gravel on the water-absorbing cushion layer 121.

[0037] The above embodiments are only for describing the preferred implementation of the utility model, and are not intended to limit the concept and scope of the utility model. Without departing from the design concept of the utility model, various modifications and improvements made by ordinary persons in the art to the technical solution of the utility model should fall within the protection scope of the utility model, and the technical contents of the utility model for protection have been fully recorded in the claims.
