[0003] In terms of the processing and manufacturing of lining steel pipes, the traditional process adopts a stiffened ring vertical construction method for production, which has slow work efficiency and high cost, and is prone to welding quality problems, seriously affecting the construction period. In recent years, relevant scholars have also proposed a process for horizontal processing of steel pipes, but the overall horizontal tire frame is obviously insufficient in stability, flexibility and maneuverability; in addition, in terms of the transportation of lining steel pipes, the existing technology usually uses fixed umbrella-shaped steel inner supports to solve the problem of steel pipe deformation during transportation. On-site length measurement, structural welding and subsequent cutting seriously affect the overall construction efficiency; finally, in terms of the assembly of lining steel pipes, especially for lining steel pipes with larger diameters and when the gap between the tunnel and the lining steel pipe is small, the transportation and assembly technology of lining steel pipes in long-distance tunnels is more difficult and risky.
