The outdoor buried steel pipe 4 and the wall-penetrating steel pipe 2 are arranged vertically and horizontally. In this embodiment, the wall-penetrating steel pipe 2 is located above the outdoor buried steel pipe 4.

[0026] The metal flexible joint 5 is made of stainless steel and is installed in a vertical direction. However, the vertical direction here is not the same as the vertical direction. The two ends of the metal flexible joint 5 are connected to the outdoor section of the steel pipe 2 that protrudes from the wall and the outdoor buried steel pipe 4, respectively.

[0027] It is worth noting that the upper end of the metal flexible joint 5 is connected to the upper connecting pipe 7 via a flange, the upper connecting pipe 7 is connected to the upper bend pipe 8 via a flange, and the upper bend pipe 8 is connected to the outdoor section of the steel pipe 2 extending out of the wall via a flange. The lower end of the metal flexible joint 5 is connected to the lower connecting pipe 9 via a flange, the lower connecting pipe 9 is connected to the lower bend pipe 10 via a flange, and the lower bend pipe 10 is connected to the outdoor buried steel pipe 4 via a flange.
