The steel pipe 16 to be installed is placed in position using a crane or pipe-lifting machine, and the construction workers manually clamp and limit the steel pipe using the clamping ring. The L-shaped positioning plate 3 is connected to the positioning plate 2. The L-shaped positioning plate 3 slides through its bottom slide groove and the top slide rail of the positioning plate 2. The hydraulic jack 52 enables the L-shaped positioning plate 3 to move horizontally perpendicular to the steel pipe axis, thereby driving the upper hydraulic jack 53, support plate 9, clamping ring 4, and steel pipe to move synchronously in the same direction, completing the vertical alignment of the two pipes, the steel pipe 16 to be installed and the steel pipe 10 already installed. Positioning plate 2 slides on the four rails corresponding to the four grooves on its bottom surface of the steel plate support 1. Driven by hydraulic jack 51, positioning plate 2 slides axially along the steel pipe, thereby causing the upper L-shaped positioning plate 3, hydraulic jack 53, support plate 9, clamping ring 4, and the steel pipe 16 to be installed to move axially towards the other installed steel pipe 10, fulfilling the design weld width requirements for the two steel pipe ends. Clamping ring 4, driven by hydraulic jack 53 and supported by support plate 9, moves vertically within a U-shaped groove via its hinge shaft 15, aligning the axis of the steel pipe 16 to be installed with the axis of the installed steel pipe 10, thus completing the pipe end connection. After the construction workers verify that the axial and radial dimensions of the two steel pipe ends, as well as the weld width error, meet the design requirements, the welders perform spot welding on the pipe ends, and then perform full welding on the pipe ends using manual or automatic welding trolleys.

[0021] likeFigure 2 As shown, at the inner corner where the L-shaped positioning plate 3 and the L-shaped positioning plate back plate 11 are connected, two ribs 13 are set to strengthen the bending deformation resistance of the L-shaped positioning plate 3, which is beneficial for the hydraulic jack 52 to transmit the pushing and pulling force to the L-shaped positioning plate 3 and the L-shaped positioning plate back plate 11.

[0022] like Figure 3 As shown, the hinge shaft 15 of the clamping ring 4 slides vertically in the U-shaped groove 12 fixed inside the back plate 11 of the L-shaped positioning plate, thereby driving the clamping ring 4 and the steel pipe 16 to be installed to move synchronously in the same direction.

[0023] like Figures 2-4 As shown, the clamping ring 4 includes an upper half-ring 41 and a lower half-ring 42. The upper half-ring 41 and the lower half-ring 42 are hinged on one side with an opening and a hinge shaft 15. The steel pipe is fastened on the other side by a fastener bolt 14. The clamping ring 4 slides vertically in the U-shaped groove 12. The steel pipe is fastened on the other side by a fastener bolt 14. A rubber pad 7 is provided on the inner side of the clamping ring 4 to prevent slipping and protect the anti-corrosion protective layer of the steel pipe. The bottom end of the clamping ring 4 is placed on the support plate 9. The support plate 9 is fixed on the hydraulic jack 53. The hydraulic jack 53 drives the support plate 9 and the moving clamping ring 4 to move vertically in the U-shaped groove to prevent the steel pipe from tilting to the side.
