[0001] This utility model patent relates to an assembled metal steel plate transportation system, which belongs to the technical field of high-pressure gas storage chambers in deep underground rock masses. Background Art

[0002] During the construction of deep underground high-pressure gas storage chambers, after the tunnel-type gas storage chamber is excavated, it is necessary to install sealing steel plates inside the chamber. The sealing steel plates are assembled on the outside to form a cylindrical shape. In the actual construction process, the cylindrical steel plates are transported and installed in sections. The diameter of the cylindrical steel plates is generally 10~16m, and the net distance between the steel plates and the chamber wall is 0.5~1.0m. The steel plates are heavy and the transportation space is narrow, which makes it difficult for conventional motor vehicle transportation methods to meet the steel plate transportation requirements. In order to solve the transportation problem of the above-mentioned cylindrical sealing steel plates in the tunnel-type gas storage chamber, it is necessary to develop a transportation system that is easy to assemble in the chamber, flexible to move, and does not affect the installation of the steel plates.
