[0026] Reference Figure 1 and Figure 2 The utility model provides a vertical prestressed grouting device, including a connecting end 1, a backing plate 2, an iron pipe 3, a threaded steel bar 4 and a fastening nut 5;

[0027] The iron pipe 3 is relatively long and is integrally sleeved on the outside of the threaded steel bar 4. The two ends of the iron pipe 3 are respectively connected to a connecting end 1. Since vertical prestressed grouting is performed here, the iron pipe 3 is vertically arranged, and the two connecting ends 1 are respectively located at the top and bottom in the height direction. The end of each connecting end 1 away from the iron pipe 3 is connected to a pad 2. The two ends of the threaded steel bar 4 pass through the corresponding connecting end 1 and the pad 2 and are each connected to a fastening nut 5. A guide part 11 is provided on the connecting end 1, and a guide port connected to the inside of the connecting end 1 and the inside of the iron pipe 3 is provided at the end of the guide part 11. The guide port can be connected to an external slurry supply pipeline.

[0028] When the vertical prestressed grouting device is in use, the threaded steel bar 4 forms a tensioning effect under the action of external equipment such as a jack, and then the fastening nut 5 is tightened to form a tightening, and then the external slurry supply equipment supplies slurry from the diversion port of the diversion part 11 of the connecting end 1 at the bottom through the external slurry supply pipeline. When the slurry fills the inside of the connecting end 1 and the inside of the iron pipe 3, it will flow out from the diversion port of the diversion part 11 of the connecting end 1 at the top, and then be led out through the external slurry supply pipeline. After the slurry solidifies, the external slurry supply pipelines connected to the two diversion parts 11 are directly cut off from the outside to complete the vertical prestressed grouting operation;

[0029] During the operation, by providing a connecting end 1, the connecting end 1 can form a reasonable connection between the iron pipe 3 and the pad 2, and by providing an independent guide part 11 on the connecting end 1, an effective guide can be formed, and a good seal can be formed with the external slurry supply pipeline to avoid slurry leakage, and the overall operation is more convenient and quick.

[0030] As an optional embodiment, the connecting end 1 further includes a main pipe 12, both ends of which are respectively connected to the iron pipe 3 and the backing plate 2, the guide part 11 is fixedly connected to the main pipe 12, and the interior of the guide part 11 can be connected to the interior of the main pipe 12;

[0031] The guide part 11 is a guide pipe, and there is an inclination angle between the guide pipe and the main pipe 12. The high end of the guide pipe is arranged away from the main pipe 12. Such an arrangement can form a good guide path and has a good guide effect. The tubular structure is easy to connect with the external slurry supply pipeline, and the sealing structure can make the two tightly sealed, further reducing the possibility of slurry leakage.

[0032] As an optional implementation, the guide part 11 is connected to the main pipe 12 by welding. The welding connection has good connection strength, which can ensure that the guide part 11 and the main pipe 12 are firmly connected to avoid leakage.

[0033] As an optional implementation, the end of the iron pipe 3 is connected to the end of the main pipe 12 by a plurality of connecting screws in the circumferential direction. The connection method here is easy to install, and the number of connecting screws is not specifically limited and can be selected according to actual use requirements.

[0034] As an optional embodiment, it also includes a reinforcement member 6, which is connected to the pad 2 and located on the outside of the connecting end 1. The reinforcement member 6 can improve the overall structural strength and prevent the concrete from cracking after the overall structure is formed.

[0035] As an optional implementation, the reinforcing member 6 is a spring, one end of which is fixedly connected to the backing plate 2 , and the spring is sleeved on the outer side of the connecting end 1 .

[0036] As an optional implementation, the reinforcement 6 is welded to the pad 2.
