[0026] Reference Figure 6 As shown, a cover plate 12 is provided on the steel pipe 1 above the grouting port 11, which can cover the grouting port 11. The edge of the cover plate 12 is provided with a connection point 13, and it is rotatably connected to the steel pipe 1 through the connection point 13. When the cover plate 12 rotates around the connection point 13, it can close the grouting port 11 when it rotates to the lowest horizontal point. (See attached figure) Figure 6 Hit 6-1 and 6-2.

[0027] In this embodiment, the connection point 13 is a connection hole, and a corresponding connecting shaft is provided on the steel pipe 1. The connection hole is sleeved on the connecting shaft and can drive the cover plate 12 to rotate 360 ​​degrees with the connecting shaft as the axis. When it rotates to the lowest horizontal point, it can close the grouting port 11. The cover plate 12 is used after the grouting is completed and the concrete has reached the required setting degree. Then, the lifting component 2 is removed, the concrete at the grouting port 11 is leveled, and the cover plate 12 is rotated to close the grouting port.

[0028] Reference Figure 1-2 As shown, the grouting pipe 21 includes a first grouting pipe 211 and a second grouting pipe 212. The first end of the first grouting pipe 211 is connected to the steel pipe 1, and the second end of the second grouting pipe 212 is a free end that can be connected to a grouting source. The check valve 22 connects the second end of the first grouting pipe 211 and the first end of the second grouting pipe 212, so that the injected concrete can pass through the second grouting pipe 212, the check valve 22 and the first grouting pipe 211 in sequence, and then enter the steel pipe 1.

[0029] Reference Figure 1-3As shown, the check valve 22 includes a check pipe 221, a check sleeve 222, and a pin 223. The check sleeve 222 is a rectangular sleeve with a check pipe 221 vertically connected to each of its two sides. The two check pipes 221 can be fitted into the first grouting pipe 211 and the second grouting pipe 212, respectively. The pin 223 passes through the check sleeve 222 and can move back and forth within it. One end of the pin 223 has a through hole 224 that matches the diameter of the grouting pipe 21. When the pin 223 moves within the check sleeve 222 until the through hole 224 aligns with the check pipe 221, the grouting pipe 21 can be grouted through the check valve 22. When the other end of the pin 223 aligns with the check pipe, it stops the concrete flow.

[0030] Reference Figure 3 As shown, the check sleeve 222 is provided with a plurality of third screw holes (not shown in the figure), and a plurality of second bolts 225 are provided corresponding to the third screw holes. The second bolts 225 can be screwed into the third screw holes and lock the pin 223 passing through the check sleeve 222.

[0031] Reference Figure 1 , 2 As shown in Figures 4 and 5, one end of the grouting pipe 21 connected to the steel pipe 1 is also provided with a connecting plate 213 extending around the grouting pipe 21. The connecting plate 213 is provided with a ring of first screw holes 226, which can be connected to the steel pipe 1 by a first bolt 15, and the inner diameter of the grouting pipe 21 is connected to the grouting port 11. The steel pipe 1 is provided with a plurality of second screw holes 14 corresponding to the first screw holes 226 around the grouting port 11. The first screw holes 226 and the second screw holes 14 are connected by the first bolt 15, thereby fixing the connecting plate 213 to the steel pipe 1.

[0032] Reference Figure 1 , 2 As shown in Figure 4, a rubber ring 4 is provided between the connecting plate 213 and the steel pipe 1, which can seal the gap between the connecting plate 213 and the steel pipe 1. The inner diameter of the rubber ring 4 is adapted to the diameter of the grouting port 11.

[0033] Reference Figure 1-2 As shown, the free end of the grouting pipe 21 is also provided with a matching clamp 3, which facilitates the connection of its free end to the pipeline of the grouting source.

[0034] This utility model discloses a method of using a steel-tube concrete jacking system, as shown in the attached figure. Figure 1-3 As shown in Figure 6, the following is an example:

[0035] First, the lifting assembly 2 is connected to the second screw hole 14 on the steel pipe 1 through the connecting plate 213 to realize the connection between the grouting pipe 21 and the grouting port 11. Pull the pin 223 to adjust the through hole 224 and the check pipe 221 to be in a connected state. Then, the free end of the grouting pipe 21 is connected to the supply pipe of the concrete source by using the clamp 3.

[0036] Next, grouting begins, and concrete is continuously injected into the steel pipe 1 through the grouting pipe 21. The concrete 5 inside the steel pipe 1 continuously overflows until it fills the entire steel pipe 1. This operation method can avoid the construction problems caused by the previous high-throw pouring.

[0037] Finally, the cover plate 12 seals the grouting port 11. After the grouting in the steel pipe 1 is completed, the pin 223 is pulled to align the other end of the pin with the check pipe 221, forming a stop for the concrete in the grouting pipe 1. The other end can be disconnected from the concrete source by removing the clamp 3. After the concrete reaches the setting requirement, the lifting component 2 is removed, and the excess concrete at the grouting port 11 is removed. Then the cover plate 12 is rotated to seal the grouting port 11. The lifting component can be used for the construction of the next steel pipe, reusing the lifting component and saving materials.

[0038] In summary, the steel pipe concrete jacking system disclosed in this utility model embodiment has the following beneficial technical effects: it solves the problems of existing technologies requiring high-altitude operations during construction, which are too difficult and dangerous, and have too many uncertain factors in construction quality, making it difficult to guarantee construction quality; in particular, it is beneficial to improve construction efficiency, save labor and materials, the system is simple to operate, quick to construct, saves time and effort, improves labor efficiency, and can meet the requirements of the site according to different construction conditions.
