Description

Technical Field

[0001] This utility model belongs to the field of waterproofing engineering technology, and in particular relates to a grouting and leak-sealing device for waterproofing projects. Background Technology

[0002] In many large-scale concrete projects, due to geological conditions and the natural environment, cracks are easily generated between concrete and rock or between concrete and steel plates, and cracks also occur between concrete blocks. This affects the quality and service life of the concrete pouring project. Repairing cracks has become a common project in the construction industry, which requires the use of grouting and sealing equipment.

[0003] For example, a floor crack waterproofing grouting device according to patent application number CN202321564756.X includes a frame, a partition plate 1 set inside the frame, a rotating shaft arranged inside the frame with a crossbar on it, one end of a pneumatic impurity removal component mounted on a partition plate 2, the other end of the pneumatic impurity removal component set outside the frame, a grouting component mounted on the frame, the outlet end of the grouting component connected to the pneumatic impurity removal component via a connecting rod, a scraper also mounted on the side of the outlet end of the grouting component, the scraper abutting against the floor surface, and a directional adjustment component arranged on the frame and partition plate 1, the directional adjustment component connected to the outlet end of the grouting component, so as to adjust the position of the outlet end of the grouting component according to the position of the crack; this application can pre-blow out the impurities in the floor cracks by setting the pneumatic impurity removal component, so as to ensure the filling quality and improve the material utilization efficiency, and at the same time, the positions of the air guide pipe, the material guide pipe and the scraper can be adjusted.

[0004] Existing technology uses pneumatic debris removal components to blow debris out of the floor gaps beforehand and can scrape off and recycle excess slurry, but it still has some shortcomings in overall use: First, air bubbles are generated during the mixing and processing of the sealing grout. These air bubbles can clog the grouting pipe or hinder the flow of the grout, resulting in incomplete filling of hollow areas. At the same time, after the air bubbles solidify, they form pores through which water can penetrate, causing local failure of the waterproof layer. Air bubbles also occupy the contact area between the grout and the substrate, reducing the adhesion and easily causing hollow areas or detachment, which seriously affects the quality of sealing. Secondly, during the mortar processing and mixing process, some slurry will stick to the inner wall of the mixing drum. After the work is completed, it is usually done by manually holding a spray gun to rinse the inner wall of the mixing device. Obviously, it is difficult to completely clean the inner wall of the mixing device by manually holding a spray gun, and it also increases the labor intensity. Summary of the Invention

[0005] This invention addresses the technical problems of existing mortar mixing processes, such as air bubbles clogging the grouting pipe, hindering grout flow, resulting in incomplete filling of hollow areas, forming pore channels after curing, allowing water penetration and causing localized failure of the waterproof layer, and air bubbles occupying the contact area between the grout and the substrate, reducing adhesion and easily causing hollow areas or detachment. Furthermore, the grout tends to adhere to the inner wall of the mixing drum during mixing, forming hard lumps after curing, affecting subsequent mixing efficiency and equipment lifespan. Manual cleaning also suffers from dead spots, high labor intensity, and low efficiency. Therefore, this invention provides a grouting and leak-sealing device for waterproofing projects.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grouting and leak-sealing device for waterproofing projects, comprising a base, a grouting tank fixedly mounted on the upper surface of the base, a spraying disc fixedly mounted on the lower surface of the inner cavity of the grouting tank, a plurality of through holes opened on the lower surface of the spraying disc, a rotating shaft rotatably mounted inside the grouting tank, a plurality of stirring blades fixedly mounted on the surface of the rotating shaft, a plurality of filter holes opened inside the stirring blades, a plurality of comb teeth fixedly mounted on the upper and lower surfaces of the stirring blades, and a conveying head provided at the bottom of the inner cavity of the grouting tank, a plurality of through grooves opened on the end face of the conveying head.

[0007] Optionally, one end of the grouting tank is connected to a feed pipe, and the top of the feed pipe is threadedly sealed with a cap.

[0008] Optionally, a fixing ring is fixedly installed on the surface of the grouting tank below the spraying disc, and multiple mounting plates are fixedly installed on the outer surface of the fixing ring. A brush that abuts against the lower surface of the spraying disc is fixedly installed on the upper surface of the mounting plate.

[0009] Optionally, two symmetrically arranged brackets are fixedly installed on the upper surface of the base, and a roller is rotatably installed inside the brackets.

[0010] Optionally, a placement platform is also fixedly installed on the upper surface of the base, and an installation box is provided on the top of the placement platform, with a grouting pipe connected to one side of the installation box.

[0011] Optionally, the grouting pipe is connected to the delivery head.

[0012] Optionally, the mounting box is connected to an air pipe on the side near and below the grouting pipe, with the air pipe facing the crack.

[0013] Optionally, a scraper is provided on the side of the mounting box near and above the grouting pipe.

[0014] In summary, compared with existing technologies, the beneficial effects of this solution are as follows: This utility model, through the setting of spraying disc, stirring blade, filter hole, comb teeth and conveying head, can remove air bubbles generated in mortar during mortar preparation, avoid air bubbles clogging the grouting pipe, reduce mortar adhesion, thereby improving mortar quality and effectively improving grouting and leak sealing effect. At the same time, after the work is completed, it can be automatically cleaned by spraying water, with no dead corners, improving the cleaning effect while reducing the labor intensity of operators. This utility model, through the installation of a box, grouting pipe, air pipe, and scraper, can remove dust from cracks before and during grouting, improve the adhesion of mortar, and thus improve the sealing effect. It can also scrape off excess grout after grouting, saving subsequent processing steps and improving the aesthetics. Attached Figure Description

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1

[0018] refer to Figure 1A grouting and sealing device for waterproofing projects includes a base 10, a caster wheel 11 fixedly installed on the lower surface of the base 10, a grouting bucket 13 fixedly installed on the upper surface of the caster wheel 11, and a handrail 12 fixedly installed on one side of the grouting bucket 13. In use, workers can push the handrail 12 and the caster wheel 11 to move the base 10 and the grouting bucket 13, which is convenient for use in different locations.

[0019] Further reference Figure 1 The top side of the grouting tank 13 is connected to a feed pipe 14, which is used to feed mortar raw materials into the grouting tank 13 for preparation. The top of the feed pipe 14 is threadedly sealed with a cap 15. After the raw materials enter the grouting tank 13, the cap 15 is sealed by the feed pipe 14, thereby preventing dust from being emitted during mortar preparation and polluting the surrounding working environment. At the same time, it can prevent external air from entering the grouting tank 13, reduce the generation of air bubbles during mortar preparation, and improve the use effect.

[0020] Further reference Figure 1 , Figure 2 and Figure 3 A spraying disc 16 is fixedly installed on the lower surface of the top of the inner cavity of the grouting tank 13. Multiple through holes 17 are opened on the lower surface of the spraying disc 16. A connecting pipe 18 that penetrates the upper surface of the grouting tank 13 is connected to the upper surface of the spraying disc 16. A water pump is connected to the connecting pipe 18. When the mortar raw material is sent into the grouting tank 13, water can be slowly sprayed into the interior of the grouting tank 13 through the spraying disc 16 and the through holes 17. This can absorb the dust generated when the mortar raw material, such as cement, is put into the grouting tank 13, and further prevent the dust from being emitted. It should be noted that after the work is completed, the spraying disc 16 continues to spray water to clean the interior of the grouting tank 13 and improve the use effect.

[0021] Further reference Figure 3 and Figure 4An inclined base plate 19 is fixedly installed at the bottom of the inner cavity of the grouting tank 13. The base plate 19 is used to collect the prepared mortar for easy transportation. A rotating shaft 20 is rotatably installed between the upper surface of the base plate 19 and the top inner wall of the grouting tank 13. A motor 21 that drives the rotating shaft 20 is fixedly installed on the upper surface of the grouting tank 13. Multiple stirring blades 22 are fixedly installed on the surface of the rotating shaft 20. Multiple filter holes 23 are opened inside the stirring blades 22, and multiple comb teeth 24 are fixedly installed on the upper and lower surfaces of the stirring blades 22. When the mortar is being prepared, the motor 21 drives the rotating shaft 20 to rotate, thereby driving the connected stirring blades 22 to rotate and stir. At the same time, the through hole 17 continues to spray. Water is used to mix mortar raw materials and water to prepare mortar. Gradually adding water and stirring avoids adding too much water at once, which can cause the mortar to become too thin or clump in some areas. This ensures that cement, sand and water are fully mixed. At the same time, continuous water addition reduces the amount of air introduced during mixing, reducing the generation of air bubbles and preventing air bubbles from affecting the strength of the mortar. As the mixing blade 22 continues to rotate, some mortar can pass through the filter hole 23 to cut it and break the air bubbles. At the same time, the comb tooth 24 combs the mortar and punctures the air bubbles, further reducing the generation of air bubbles. This prevents air bubbles from forming pores after the mortar is fixed, which would reduce the quality of the mortar and improve the sealing effect in the subsequent grouting process.

[0022] Further reference Figure 3 and Figure 4 A conveying pump 25 is fixedly installed on one side of the grouting tank 13 on the upper surface of the base 10. The feed end of the conveying pump 25 is connected to the conveying head 26. The conveying head 26 is located inside the grouting tank 13 and at the inclined bottom end of the base plate 19. A through groove 27 is opened on the surface of the spraying plate 16. After the mortar is prepared, the conveying pump 25 conveys it. The through groove 27 can filter the mortar, further remove air bubbles, improve the mortar quality, and ensure the sealing effect.

[0023] Further reference Figure 1 Two symmetrically arranged brackets 31 are fixedly installed on the upper surface of the base 10 on one side of the conveying pump 25. A drum 32 is rotatably installed between the two brackets 31 for winding up the conveying pipe connecting the conveying pump 25. A rocker arm 33 for driving the drum 32 is fixedly installed on the outside of the brackets 31.

[0024] Further reference Figure 1 and Figure 6 A placement platform 34 is fixedly installed on one side of the bracket 31 on the upper surface of the base 10. An installation box 35 is placed on the top of the placement platform 34. One side of the installation box 35 is connected to a conveying pipe, and the other side is connected to a grouting pipe 36. When in use, the installation box 35 can be lifted, the grouting pipe 36 can be aligned with the leak, and grouting can be performed. The conveying pipe is wound up by the drum 32, which can be used in different height scenarios and has practicality.

[0025] Further reference Figure 6 The mounting box 35 has a built-in air pump, and an air pipe 37 is fixedly installed on the side of the mounting box 35 near the grouting pipe 36. The air pipe 37 is connected to the air outlet of the air pump and is located below the grouting pipe 36. The end face of the air pipe 37 is inclined towards the crack. Before grouting, it can blow away dust in the crack, and it can also blow away dust during grouting, improving adhesion and the grouting and sealing effect. Further reference Figure 6 A scraper 38 is fixedly installed on the side of the installation box 35 near the grouting pipe 36. The scraper 38 is located above the grouting pipe 36. During grouting, it can scrape off excess grout, improving the aesthetics of grouting and sealing. It should be noted that in this solution, the scraper 38 is telescopically installed inside the installation box 35, so that the scraper 38 can always be in contact with the crack, improving the performance. Example 2

[0026] A grouting and leak-sealing device for waterproofing projects, further illustrated in Embodiment 1, is provided for reference. Figure 3 and Figure 5 The surface of the rotating shaft 20 is attached to the spraying disc 16. A fixing ring 28 is fixedly installed below the spraying disc 16. Multiple mounting plates 29 are fixedly installed on the outer surface of the fixing ring 28. A brush 30 that abuts against the lower surface of the spraying disc 16 is fixedly installed on the upper surface of the mounting plate 29. In use, while the mortar preparation rotating shaft 20 rotates, it drives the fixed ring 28 connected to it to rotate. The rotation of the fixing ring 28 drives the mounting plate 29 and the brush 30 to rotate, which can scrape the lower surface of the spraying disc 16, prevent dust from sticking to the through hole 17 and causing blockage, and improve the spraying effect.

[0027] Finally, it should be noted that the connection and fixing methods of the various parts of the utility model grouting and sealing equipment for waterproofing projects can all be achieved by conventional mechanical connection structures. The control system and connection methods required between multiple electrical components and drive components can also be achieved by conventional means and can be equipped with corresponding sensors and detectors.
