Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building industry technology, and specifically relates to a leak-proof grouting device. Background Technology
[0002] During grouting or injection construction, horizontal grouting is prone to problems such as grout leakage and gaps at the top, resulting in incomplete compaction. For example, when pouring lightweight concrete into a light steel keel mesh wall, the continuous pouring height of the lightweight concrete should not exceed 1.5 meters. Therefore, when the pouring height is too high, multiple grouting sessions are required. In this case, holes need to be made in the steel mesh in the wall, and the pump pipe extends into the mesh wall through the holes for pouring. However, after pouring, the pipe needs to be pulled out. When the pump pipe is pulled out, the volume of concrete occupied by the pump pipe decreases, resulting in incomplete grouting at the top. At the same time, the process of pulling out the pipe will also bring out some concrete, resulting in grout leakage and incomplete compaction. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0028] Example 1
[0029] See Figures 1-4This embodiment discloses a leak-proof grouting device, including a chassis, a fixing frame 8, a grout-blocking component, and a turntable. The chassis is provided with a grouting port 9, and the grout-blocking component seals or opens the grouting port 9 by rotating. The fixing frame 8 is set on the chassis and is used to fix the position of the pump pipe 11 and align the pipe opening of the pump pipe 11 with the grouting port 9.
[0030] In this embodiment, the fixing frame 8 is circular and coaxial with the grouting port 9. Several connecting parts 12 are connected between the fixing frame 8 and the chassis, and an installation gap is left. The grout-blocking part is embedded in the installation gap.
[0031] The grout-blocking component of this embodiment includes multiple petal-shaped rotating plates 7. When all rotating plates 7 rotate inward toward the grouting port 9, they can close and seal the grouting port 9. When all rotating plates 7 rotate outward toward the grouting port 9, they can open the grouting port 9. Among them, the connecting parts 12 between the fixing frame 8 and the chassis are arranged at equal intervals along the circumference of the fixing frame 8. A rotating plate 7 is provided between each pair of connecting parts 12, and one corner of each rotating plate 7 is rotatably connected to each connecting part 12.
[0032] In this embodiment, the grout-blocking component is positioned between the fixed frame 8 and the chassis. This makes the connection between the fixed frame 8, the grout-blocking component, and the chassis more compact and reliable. In particular, after the fixed frame 8 is connected and assembled with the pump pipe 11, it can better connect with the grouting port 9, effectively preventing grout leakage. In this embodiment, the inner hole of the annular ring of the fixed frame 8 can be set to match the size of the grouting port 9. On the other hand, the connecting piece 12 between the fixed frame 8 and the chassis can be used to set various rotating pieces 7. The rotating pieces 7 are not affected by the pump pipe 11 or the fixed frame 8 when rotating, realizing the rotation to close or open the grouting port 9. The design is ingenious and easy to use. Furthermore, in this embodiment, the grout-blocking component is divided into multiple petal-shaped rotating pieces 7, and the grouting port 9 is blocked or opened by rotating and cutting in and out, which can more conveniently and quickly block the grouting port 9 to prevent grout leakage.
[0033] Furthermore, the connector 12 in this embodiment can be a rivet or a pin. For example, a rivet can be used to fix the frame 8 to the chassis, and the rivet can also be used as a rotation center to movably rivet the rotating piece 7 to it, so that the rotating piece 7 can rotate.
[0034] In this embodiment, the turntable is annular; the grouting port 9, the fixing frame 8, and the grout-blocking component are all located in the inner hole of the turntable; each rotating plate 7 is provided with an intermediate connecting plate 10 between itself and the turntable. The intermediate connecting plate 10 is arc-shaped, with one end of the intermediate connecting plate 10 rotatably connected to one corner of the rotating plate 7, and the other end of the intermediate connecting plate 10 rotatably connected to the turntable; when the turntable rotates, it synchronously drives all the intermediate connecting plates 10 and the rotating plates 7 to rotate, thereby controlling each rotating plate 7 to rotate inward or outward towards the grouting port 9, thereby sealing or opening the grouting port 9. This embodiment achieves synchronous rotation of each rotating plate 7 through the setting of the turntable and the intermediate connecting plate 10, which is convenient to operate and can quickly seal or open the grouting port 9, providing good convenience.
[0035] Furthermore, in this embodiment, the rotating plate 7 and the intermediate connecting plate 10, as well as the intermediate connecting plate 10 and the turntable, can be riveted together to achieve rotatability. Of course, other implementation methods can also be adopted with reference to the prior art.
[0036] In this embodiment, the chassis is provided with several limiting members 4, and the turntable is provided with an arc-shaped limiting groove 3 extending in the circumferential direction. The limiting members 4 are embedded in the arc-shaped limiting groove 3. Through the cooperation of the limiting members 4 and the arc-shaped limiting groove 3, the rotation of the turntable can be guided and limited, making the rotation of the turntable more reliable and stable, thereby enabling the rapid rotation of multiple rotating pieces 7. In addition, the end of the limiting member 4 in this embodiment can be designed to be larger than the arc-shaped limiting groove 3, so that the limiting member 4 can guide the turntable while also appropriately fixing the turntable. The limiting member 4 in this embodiment can be a button structure, rivet, pin, etc.
[0037] Furthermore, this embodiment provides multiple arc-shaped limiting grooves 3, distributed along the circumferential direction, with each arc-shaped limiting groove 3 corresponding to a multiple limiting component 4. This structure allows the ends of the arc-shaped limiting grooves 3 to limit the rotation angle of the turntable, preventing excessive rotation angle of the turntable from damaging other components.
[0038] In addition, the turntable in this embodiment is provided with a handle 6, which extends radially outward, making it easier for workers to rotate the turntable at the construction site.
[0039] Furthermore, the mounting bracket 8 in this embodiment is provided with a connecting cylinder 13 for connecting to the pump pipe 11, and the connecting cylinder 13 extends away from the chassis. This allows for easier connection to the pump pipe 11 via the cylindrical connecting cylinder 13. For example, the port of the pump pipe 11 can be fitted onto the connecting cylinder 13, and then the port of the pump pipe 11 can be locked to the connecting cylinder 13 using an annular hose clamp 14. The operation is simple and reliable, and the assembly and disassembly are convenient.
[0040] To facilitate the fixing of the chassis to the sidewalls, this embodiment has multiple through holes 5 on the chassis, which are then connected to the sidewalls of the space to be grouted through the through holes 5. Specifically, through holes 5 can be set at the four corners of the chassis, and then steel wires can be passed through the through holes 5 and tied to the sidewalls for fixation. The structure is simple and easy to assemble and disassemble.
[0041] In this embodiment, the pump pipe 11 and the connecting cylinder 13 are connected by an annular hose clamp 14, and the chassis is fixed to the side wall. When grouting is required, the turntable is rotated to open the grouting port 9 and concrete can be poured. The pump pipe 11 does not need to be inserted into the wall, and there will be no problems such as non-compacted concrete and top settlement near the pump pipe 11 caused by the pipe pulling process. After the pouring is completed, the turntable is rotated in time to seal the grouting port 9, which can effectively prevent concrete from being brought out during the pipe pulling process and prevent grout from overflowing.
[0042] Example 2
[0043] See Figure 5 The difference between this embodiment and embodiment 1 is that the fixing frame 8 in this embodiment includes two fixing plates 15. The two fixing plates 15 are circular and coaxial with the grouting port 9. Several connecting pieces 12 are connected between the two fixing plates 15 and an installation gap is left; the grout blocking piece is embedded in the installation gap.
[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
