[0002] The ultra-high-speed low-vacuum pipeline maglev transportation system is a transportation system that uses superconducting magnetic levitation technology, low-vacuum pipeline technology and superconducting synchronous linear motor technology to achieve high-speed operation of superconducting wheel-rail trains in closed pipelines. Figure 2 The system requires the laying of steel structure pipelines along the line. The bottom of the pipeline is a "U"-shaped pipe beam, the outside is a pipe shell, the inner wall of the pipe beam has a module prefabricated plate, and the bottom has a rail support platform. The pipeline is erected at a certain height from the ground, and the pipeline is in a low vacuum state. Among them, the module prefabricated plate is the bearing platform of the magnetic levitation magnetic resistance body, which is symmetrically installed on both sides of the pipe beam.

[0003] The target of the ultra-high-speed low-vacuum pipeline maglev transportation system is to achieve a maximum speed of 1000km / h near the ground, so the design requirements for steel structure pipelines are extremely high.
