[0024] Figure 3 It is a top view of the filter plate in the present invention. DETAILED DESCRIPTION

[0025] The features of the present invention and other related features are further described in detail below through embodiments in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art:

[0026] like Figure 1-3 As shown in the figure, marks 1-24 respectively represent: grouting device 1, slurry delivery pipeline 2, grouting device 3, connecting bolt 4, rotating bolt 5, central axis 6, filter plate 7, filter port 8, center rod 9, lifting bottom plate 10, lifting handle 11, lifting elastic body 12, reaction top plate 13, slurry outlet 14, clearing rod 15, force handle 16, clearing elastic body 17, ejector pin 18, fixing bolt 19, slurry isolation spring piece 20, filter residue funnel 21, hanging rod 22, lifting area 23, hook 24.

[0027] Example: Figure 1 As shown, the zoned grouting device for prefabricated component connection in this embodiment consists of three parts: a grouting device 1, a grouting pipeline 2, and a grouting device 3. The grouting device 1 is used as a grouting area to receive the grouting slurry for prefabricated component connection and to perform pressure grouting and stirring on the slurry. The grouting pipeline 2 is used to transport the slurry from the grouting device 1 to the grouting device 3, and the grouting device 3 is used to improve the density and quality of the grouting.

[0028] Specifically, if Figure 1As shown, the grouting pipeline 2 is detachably fixedly connected to the lifting area 23 at the bottom of the grouting device 1 by connecting bolts 4, and the other end of the grouting pipeline 2 is detachably fixedly connected to the grouting device 3 by rotating bolts 5. The grouting device 1 can be horizontally rotated around the rotating bolts 5 together with the grouting pipeline 2. When in use, the grouting device 3 is placed at the connection position of the assembled component, that is, in the area to be grouted. By rotating the grouting device 1 and the grouting pipeline 2, the lifting device for upper pressure injection can be placed in an area that is more convenient for operation, avoiding site constraints at the construction site. After use, the three parts of the grouting device 1, the grouting pipeline 2, and the grouting device 3 can be detached and separated for easy storage and transportation.

[0029] like Figure 1 As shown, the grouting device 1 is provided with a central axis 6, and the upper area along the central axis 6 is surrounded by filter plates 7 that gradually slope downward. The central axis 6 can be stabilized inside the grouting device 1 by the support of the filter plates 7. Figure 3 As shown, a plurality of filter ports 8 are distributed on the filter plate 7, which are used to filter the residue in the slurry, ensure the purity of the slurry flowing into the grouting device 3, and improve the grouting quality. The central axis 6 is a hollow structure, and a central rod 9 that can move up and down is arranged inside it. The central rod 9 passes through the central axis 6 and passes through the reaction top plate 13 located at the bottom of the central axis 6. A lifting bottom plate 10 is connected to the bottom of the central rod 9, and a lifting handle 11 is connected to the top. The lifting bottom plate 10 and the reaction top plate 13 are both concave structures facing the slurry delivery pipeline 2, that is, the concave openings of both are facing the slurry delivery pipeline 2, and the maximum contour of the lifting bottom plate 10 is smaller than the minimum contour of the reaction top plate 13. At this time, when the lifting bottom plate 10 moves up and down with the central rod 9, the reaction top plate 13 sets an upper limit on the lifting bottom plate 10, that is, the lifting bottom plate 10 cannot continue to move up when it moves up to the reaction top plate 13.

[0030] When in use, the center rod 9 is moved up and down by the lifting handle 11. When the center rod 9 is moved downward, the lifting bottom plate 10 can generate a downward thrust on the slurry, which is conducive to the slurry to smoothly pass through the slurry delivery pipe 2 into the grouting device 3, and realize a certain degree of pressure grouting; when the center rod 9 is moved upward, the reaction top plate 13 can buffer the upward force on the slurry caused by the upward movement of the lifting bottom plate 10, and play a role in stirring the slurry by dispersing the force to the surrounding area, thereby ensuring the uniformity of the slurry; on the other hand, the concave structure can also prevent the slurry from splashing out of the grouting device 1 upward. In general, the upward and downward movement of the center rod 9 in this embodiment plays two different roles, among which the downward movement mainly plays the role of pressure grouting, while the upward movement plays the role of stirring the slurry. In addition, the inclined filter plate 7 plays a certain guiding role on the slurry, improving the slurry stirring efficiency and quality achieved by the cooperation of the lifting bottom plate 10 and the reaction top plate 13.

[0031] like Figure 1As shown, the bottom of the grouting device 1 is a lifting area 23 for lifting the bottom plate 10 to move up and down. Between the lifting handle 11 and the central axis 6, there are lifting elastic bodies 12 distributed around the central rod 9. When a downward force is applied to the lifting handle 11, the lifting elastic body 12 is compressed and drives the central rod 9 and the lifting bottom plate 10 to move downward, thereby realizing pressure grouting; and when the downward force is released, the lifting elastic body 12 stretches by relying on its own tension as a rebound force and drives the central rod 9 and the lifting bottom plate 10 to move upward automatically, thereby realizing slurry stirring. The lifting elastic body 12 can also prevent the slurry from entering the area around the central rod 9 in the central axis 6, ensuring that the central rod 9 can move freely.

[0032] like Figure 1 As shown, the bottom of the grouting device 3 is a slurry outlet 14, and the slurry finally enters the prefabricated component connection area through the slurry outlet 14. A dredging rod 15 is arranged inside the grouting device 3. During the grouting process, the dredging rod 15 can drive the ejector pin 18 arranged at the bottom thereof to extend out of the grouting device 3 from the slurry outlet 14 and repeatedly insert into the grouting liquid flowing out from the slurry outlet 14. The insertion of the ejector pin 18 can release the air wrapped in the slurry on the one hand, and enhance the density and quality of the grouting on the other hand. A force-applying handle 16 is arranged at the top of the dredging rod 15. A dredging elastic body 17 is distributed around the dredging rod 15 between the force-applying handle 16 and the grouting device 3. The working principle of the dredging elastic body 17 is the same as that of the lifting elastic body 12. The dredging elastic body 17 is compressed as the dredging rod 15 moves downward and drives the dredging rod 15 to move upward through its tension.

[0033] like Figure 1 As shown, the clearing rod 15 is located in the top area of ​​the rotating bolt 5, and is connected to the slurry isolation spring piece 20 fixedly connected to the inner wall of the grouting device 3 through the fixing bolt 19. The slurry isolation spring piece 20 can move up and down with the clearing rod 15 and freely expand and contract through its own elasticity. The slurry isolation spring piece 20 is mainly used to prevent the slurry from entering the grouting device 3 above the slurry isolation spring piece 20, and to avoid the slurry from overflowing through the top of the grouting device 3, thereby ensuring that the slurry outlet 14 is the only slurry outflow channel.

[0034] like Figure 2 As shown, a filter residue funnel 21 is provided near the contact position between the filter plate 7 and the grouting device 1. The filter residue funnel 21 is embedded in the grouting device 1 through a hanging rod 22 and a hook 24, and can be used to collect the residue filtered out by the filter plate 7, which is easy to operate.

[0035] In practical application, this embodiment includes the following steps:

[0036] (1) The grouting device 1, the grouting pipeline 2 and the grouting device 3 are connected in sequence, and the grouting outlet 14 is placed at the connection position of the assembled component, that is, in the area to be grouted. The rotating bolt 5 is adjusted so that the grouting pipeline 2 and the grouting device 1 are placed in a position that is convenient for operation.

[0037] (2) Slurry is poured into the grouting device 1. The slurry flows into the bottom of the grouting device 1 through the filter port 8 on the filter plate 7, and then flows into the grouting device 3 through the slurry delivery pipe 2.

[0038] (3) As the amount of grouting increases, downward pressure is applied to the center rod 9 through the lifting handle 11, prompting the lifting bottom plate 10 to press the slurry downward for pressure grouting. The lifting handle 11 is then released, and the center rod 9 drives the lifting bottom plate 10 to move upward under the tension of the lifting elastic body 12. The upward force exerted by the lifting bottom plate 10 on the slurry is dispersed by the reaction top plate 13 at the bottom of the central axis 6 to stir the slurry.

[0039] (4) Repeat step (3). The downward thrust facilitates the slurry to enter the grouting device 3 smoothly. The upward and downward pulling can ensure the uniformity of the slurry by stirring, and can also prevent the slurry from splashing out of the grouting device 1.

[0040] (5) Apply downward pressure to the dredging rod 15 through the force-applying handle 16 to cause the ejector pin 18 to be inserted into the injected grout. Then release the force-applying handle 16, and the dredging rod 15 drives the ejector pin 18 to move upward under the tension of the dredging elastic body 17.

[0041] (6) Repeating step (5) can release the air trapped in the grouting liquid and enhance the density and quality of the grouting. In this way, the grouting of the connection area of ​​the prefabricated components is completed, the grouting quality is improved, and the connection strength and integrity between the prefabricated components are ensured.

[0042] In the specific implementation of this embodiment: the grouting device 1, the grouting pipeline 2, the grouting device 3, etc. can be made of composite plastics or metals with light weight, good rigidity, good corrosion resistance, and easy cleaning. The filter plate 7, the central axis 6, the central rod 9, the reaction top plate 13, the lifting bottom plate 10, etc. can be made of composite plastics with light weight, good rigidity, good corrosion resistance, and easy cleaning. The dredging rod 15, the ejector pin 18, etc. can be made of metals with light weight, good rigidity, good corrosion resistance, and easy cleaning.

[0043] Although the above embodiments have described in detail the concepts and embodiments of the present invention with reference to the accompanying drawings, ordinary technicians in this field can recognize that various improvements and changes can still be made to the present invention without departing from the scope of the claims, so they are not described one by one here.
