The cross column 11 is symmetrically fixedly connected to the surface of the movable plate 9 away from the connecting plate 10 along its center. The rack 12 is fixedly connected to the surface of the cross column 11. An extension 15 is symmetrically fixedly connected to the surface of the surrounding plate 3. One extension 15 is fitted with the first base 1, and the other extension 15 is fitted with the second base 2. The surface of the extension 15... A cylinder 16 is fixedly connected symmetrically along the center of the surface. A cylinder 17 is threadedly connected to the surface of the cylinder 16. An arc-shaped block 14 is rotatably mounted on the surface of the cylinder 17. Multiple arc-shaped blocks 14 are fixedly connected to the surrounding plate 3. A transmission gear 13 is meshed with the surface of the rack 12. The transmission gear 13 is fixedly connected to the cylinder 17. Multiple racks 12 are located at the end of the surface of the horizontal column 11 away from the movable plate 9, which plays an adjustment role. As the U-shaped column 7 moves, multiple adjusting blocks 19 can contact the surfaces of the first base 1 and the second base 2. The positioning block 18 retracts and cooperates with the annular plate 8 to complete the adjustment and limit the position of the annular plate 8.

[0025] The positioning device includes a positioning block 18, an adjusting block 19, a first movable column 20, a first spring 21, a second movable column 22, a second spring 23, a first U-shaped plate 24, a second U-shaped plate 25, a first top block 26, a second top block 27, and a groove 28. The first top block 26 is symmetrically mounted on the surface of the U-shaped column 7 away from the connecting plate 10. The first movable column 20 is fixedly connected to the surface of the first top block 26. The adjusting block 19 is fixedly connected to the end of the first movable column 20 away from the first top block 26. All four adjusting blocks 19 are slidably mounted with the annular plate 8. A first spring 21 is sleeved on the surface of the first movable column 20. One end of the first spring 21 is fixedly connected to the adjusting block 19. The first U-shaped plate 24 is fixedly connected to the end of the first spring 21 away from the adjusting block 19. Multiple first U-shaped plates 24 are also present. All are fixedly connected to the annular plate 8. Positioning blocks 18 are symmetrically installed between the first base 1 and the second base 2 along the center. A second movable column 20 is fixedly connected to the surface of the positioning block 18. A second top block 27 is fixedly connected to the end of the second movable column 22 away from the positioning block 18. A second U-shaped plate 25 is slidably connected to the surface of the second movable column 22. Multiple second U-shaped plates 25 are fixedly connected to the annular plate 8.

A groove 28 is opened on the surface of the second top block 27. Multiple grooves 28 are installed in conjunction with the U-shaped column 7 to play a positioning role, which facilitates the installation and limiting of the surrounding plate 3, so that it can maintain stability during pouring.

[0026] The second spring 23 is initially compressed. The reaction force generated by the compression of the second spring 23 acts on the surface of the positioning block 18, so that the positioning block 18 can extend out of the annular plate 8 and be placed between the first base 1 and the second base 2.

[0027] The surface of the first top block 26 is provided with a sloping groove 29. The edge of the end face of the U-shaped column 7 away from the connecting plate 10 is chamfered. The chamfered surface can contact the surface of the sloping groove 29, thereby driving the first top block 26 to move.

[0028] A fixing plate 30 is symmetrically fixed to one end of the U-shaped column 7 away from the connecting plate 10 along the center. A limit strip 31 is fixedly connected to the surface of the multiple fixing plates 30 away from the U-shaped column 7. The limit strip 31 is installed in conjunction with the groove 28.

[0029] A fiber cloth 32 is installed on the surface of the annular plate 8 between the first substrate 1 and the second substrate 2. The fiber cloth 32 can contact the surface of the poured cement to avoid sticking to the cement, which facilitates the disassembly of the annular plate 8. Fiber cloth 32 can be provided on the inner wall of the surrounding plate 3 and the surface of the positioning block 18 to facilitate disassembly after the pouring is completed.

[0030] It should be noted that during implementation, circular grooves can be provided on the surfaces of the first substrate 1 and the second substrate 2, which can cooperate with one end of the cylinder 17 to ensure the stable installation of the enclosure 3.

[0031] It should be noted that the first substrate 1 and the second substrate 2 are existing reinforced concrete pipes.

[0032] Working principle and usage process of this invention:

[0033] During use, the arc-shaped limiting block is fitted with the surface of the first base 1, the surrounding plate 3 is fitted onto one end of the surface of the first base 1, the annular plate 8 is fitted with the inner wall of the first base 1, and under the elastic force of the second spring 23, the positioning block 18 can contact the end face of the first base 1. The second base 2 then fits with the annular plate 8 and also fits with the surrounding plate 3. The end face of the second base 2 close to the first base 1 contacts the surface of multiple positioning blocks 18 for initial placement and positioning. Both extension edges 15 are fixedly connected to the surrounding plate 3, and the two extension edges 15 respectively contact the surfaces of the first base 1 and the second base 2, using the friction between them and the first base 1 and the second base 2 to install and position the surrounding plate 3.

[0034] Before pouring, multiple positioning blocks 18 are positioned between the first base 1 and the second base 2 to provide initial installation positioning for the annular plate 8, while leaving a gap between the first base 1 and the second base 2.

[0035] Push the U-shaped column 7 so that it moves closer to the first top block 26. The arc-shaped limiting plate 6 and the first base 1 move relative to each other. One end of the U-shaped column 7 is chamfered. The chamfer contacts the inclined groove 29 on the surface of the first top block 26 and moves relative to each other. The first movable column 20 moves with the first top block 26. The first spring 21 is stretched. When the inclined groove 29 separates from the U-shaped column 7, all four adjusting blocks 19 are in close contact with the surface of the first base 1 to limit the installation of the annular plate 8.

[0036] Immediately afterwards, the limiting strip 31 contacts the groove 28. As the U-shaped column 7 continues to move, the second top block 27 moves along the surface of the limiting strip 31. The movement of the second top block 27 drives the second movable column 22 to move. The positioning block 18 gradually engages with the annular plate 8 and exits the gap between the first base 1 and the second base 2.

[0037] The U-shaped column 7 contacts the inclined grooves 29 on the surfaces of the other four first top blocks 26, causing the other four adjusting blocks 19 to contact the inner wall of the second base 2, further limiting the installation of the annular plate 8.

[0038] The movement of the U-shaped column 7 simultaneously drives the connecting plate 10 and the movable plate 9 to move. The rack 12 meshes with the two transmission gears 13 in sequence, driving the transmission gears 13 to rotate. The cylinder 17 rotates with the transmission gears 13. The cylinder 17 is connected to the cylinder 16 by threads. One end of four cylinders 17 is in close contact with the surface of the first base 1, and one end of the other four cylinders 17 is in close contact with the surface of the second base 2, thus limiting the installation of the enclosure plate 3 and simultaneously limiting the installation of the enclosure plate 3 and the annular plate 8.

[0039] The material is poured through the feed pipe 5 to fill the gap between the first substrate 1 and the second substrate 2, ensuring sealing and plugging effect, while also ensuring the stability of the connection between the first substrate 1 and the second substrate 2.
