At the same time, sealing strips 5 are arranged in the installation grooves 402 at both ends of the connecting plates 4 for sealing. During use, the connecting plates abut against the sealing strips, so that the sealing strips 5 are tightly attached to the inner walls of the connecting plates 4 and the lifting section 1 and the standard section 2, so that the adjacent two adjacent standard sections 2 and the standard section 2 and the lifting section 1 are connected through multiple groups of connecting plates 4 to ensure their overall air tightness.

[0021] During installation, first connect the load-bearing parts of lifting section 1 to the lifting equipment, lift the steel lined pipe lifting section 1 through the lifting equipment, and then install the standard section 2 on the lower side of lifting section 1. After the installation is completed, lift the installed lifting section 1 and standard section 2 again through the lifting equipment, and then continue to install standard section 2 on the lower side of standard section 2 connected to lifting section 1. After the installation is completed, lift the height of standard section 2 again, and continue to install, and repeat the above steps.

After tightening the nut 303, the connection can be completed. At the same time, under the pressure of the nut 303, the connecting plate 4 abuts against the sealing strip 5 and the sealing gasket 501 to ensure the overall air tightness. After the installation is completed, lift the installed lifting section 1 and standard section 2 again through the lifting equipment, and then continue to install the standard section 2 on the lower side of the standard section 2 connected to the lifting section 1.
