[0029] The slurry dripping mechanism 3 includes a horizontal guide tube 31, a vertical guide tube 32, a liquid outlet hose 33 and a slurry dripping head 34. The horizontal guide tube 31 is horizontally connected to one side of the base 1 and can move in the horizontal direction on one side of the base 1. The vertical guide tube 32 is vertically connected to one end of the horizontal guide tube 31 and can move in the vertical direction at one end of the horizontal guide tube 31. The bottom end of the vertical guide tube 32 is connected to the slurry dripping head 34; one end of the liquid outlet hose 33 is connected to the liquid outlet pipe of the grouting bucket 2, and the other end of the liquid outlet hose 33 is connected to the slurry dripping head 34.

[0030] Next, the grouting device for the construction of the water-stabilizing structure layer of the pavement according to this exemplary embodiment will be further described.

[0031] In some embodiments of the present application, the grouting device includes a base 1, a grouting bucket 2 and a grouting mechanism 3. The base 1 is a square base 1, and the base 1 is mounted on the flat plate of the water-stable paver by bolts, which is convenient for disassembly and assembly. The grouting bucket 2 is arranged on the base 1, and the grouting mechanism 3 is arranged outside the grouting bucket 2, corresponding to the edge of the cement-stabilized gravel, so that the grouting device can be driven to drip grout on the edge of the structural layer gravel while the water-stable paver is working to increase the quality of the water-stable edge construction.

[0032] In some embodiments of the present application, the above-mentioned slurry dripping mechanism 3 includes a horizontal guide tube 31, a vertical guide tube 32, a liquid outlet hose 33 and a slurry dripping head 34. The above-mentioned horizontal guide tube 31 is horizontally connected to one side of the base 1 and can move in a horizontal direction on one side of the base 1. The above-mentioned vertical guide tube 32 is vertically connected to one end of the horizontal guide tube 31 and can move in a vertical direction at one end of the horizontal guide tube 31. The bottom end of the vertical guide tube 32 is connected to the slurry dripping head 34; one end of the liquid outlet hose 33 is connected to the liquid outlet pipe of the grouting bucket 2, and the other end of the liquid outlet hose 33 is connected to the slurry dripping head 34. When dripping slurry on the edge of the water-stabilizing structure, the horizontal guide tube 31 is moved left and right to a suitable horizontal position, and the vertical guide tube 32 is moved up and down to a suitable vertical position, so as to adjust the dripping head 34 to a suitable horizontal position so that it corresponds to the edge of the water-stabilizing structure, and adjust it to a suitable dripping height to facilitate dripping and prevent splashing; the cement slurry in the grouting barrel 2 flows out from the dripping head 34 through the liquid outlet pipe and the liquid outlet hose 33 to the gravel of the water-stabilizing structure edge layer, thus completing the edge grouting.

[0033] As a preferred embodiment, a plurality of T-shaped first fixed sleeves 35 are provided on one side of the base 1, and the horizontal guide tube 31 is inserted into the first fixed sleeve 35 and locked by a fastener 36; a T-shaped second fixed sleeve 37 is provided at one end of the horizontal guide tube 31, and the vertical guide tube 32 is inserted into the second fixed sleeve 37 and locked by a fastener 36. That is, the horizontal guide tube 31 can move horizontally in the plurality of first fixed sleeves 35 to adjust its horizontal position, and can be locked by a fastener 36 after being adjusted to a suitable position; the fastener 36 can be a hand wheel fastening bolt for easy operation. Similarly, the vertical guide tube 32 can move up and down in the second fixed sleeve 37, and can be moved to a suitable position and fixed by a hand wheel fastening bolt. The above simple structure can be used to adjust the position of the drip head 34, so that it is located at a suitable dripping horizontal position and height, thereby improving the dripping quality.

[0034] As a preferred embodiment, the liquid outlet pipe is arranged at the lower part of the side wall of the grouting bucket 2, and an electric valve 38 and a manual valve 39 are connected between the liquid outlet hose 33 and the liquid outlet pipe. By setting the electric valve 38 and the manual valve 39, the grout dripping can be realized by electric or manual operation. When the grout dripping position is reached, the electric valve 38 or the manual valve 39 can be opened to realize the grout dripping. The manual valve 39 can prevent the grout dripping from failing when the electric valve 38 fails.

[0035] As a preferred embodiment, the dripping head 34 includes a shell 341 with an opening at the bottom, and the side wall of the shell 341 can be designed to be sloped, so that the slurry can slide down the slope. The vertical guide tube 32 is connected to the top of the shell 341, and the dripping head 34 is adjusted and supported by the vertical guide tube 32. The liquid outlet hose 33 is connected to the liquid inlet on one side of the shell 341, and a splash-proof rubber block 342 is provided at a position relative to the liquid inlet on the inner wall of the shell 341, which is fixed to the shell 341 by bolts. By arranging the splash-proof rubber block 342 on the opposite side of the liquid inlet of the shell 341, it can be avoided that the dripping slurry flows too fast and the impact force is too large to cause splashing at the dripping head 34, thereby causing the slurry to splash to the edge of the structural layer, affecting the edge grouting quality.

[0036] As a preferred embodiment, the grouting bucket 2 comprises a bottom plate 25, a barrel body 26 and a stirring mechanism 23. The barrel body 26 is arranged on the bottom plate 25, and the stirring mechanism 23 is arranged inside the barrel body 26. A feed port 21 is provided on the top of the barrel body 26, and a protective cover 24 is provided on the top of the barrel body 26. A handle 22 is provided on the side wall of the barrel body 26. A certain proportion of mud is added through the feed port 21, and then stirred through the internal stirring mechanism 23 to prevent mud from segregating. The protective cover 24 is used to prevent splashing when mud is added. The handle 22 can be provided to facilitate installation or disassembly of the grouting bucket 2.

[0037] As a preferred embodiment, the bottom plate 25 is connected to a sewage pipe 4 which is in communication with the interior of the barrel body 26 , and the remaining mud or cleaning waste water after the daily construction is completed is discharged through the sewage pipe 4 at the bottom.

[0038] As a preferred embodiment, the stirring mechanism 23 includes a driving motor, a worm gear reducer and an agitator. The driving motor and the worm gear reducer are both mounted on the bow-shaped fixing seat at the top of the barrel 26. The input end of the worm gear reducer is connected to the output end of the driving motor. The agitator is located inside the barrel 26 and connected to the output end of the worm gear reducer. The agitator is driven to rotate by the worm gear reducer to stir the slurry inside the grouting barrel 2 to avoid mud segregation. Specifically, the agitator includes a stirring shaft and stirring blades. The stirring shaft is connected to the output end of the worm gear reducer. The stirring blades are welded to the stirring shaft in four layers from top to bottom.

[0039] Working principle: A certain proportion of mud is added through the feed port 21, and then stirred through the internal stirring system (to prevent mud segregation). When the water-stabilized paver drives to the road surface and adjusts the drip head 34 to correspond to the water-stabilized edge, the mud is released along the liquid outlet hose 33 and then through the drip head 34 by opening the electric valve 38 or the manual valve 39. After the daily construction is completed, the remaining mud or cleaning wastewater is discharged through the drain pipe 4 at the bottom of the barrel 26, that is, the cement slurry is dripped on the edge of the cement-stabilized gravel quickly and efficiently, thereby improving the construction quality of the water-stabilized edge.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
