Abstract

The invention relates to a tunnel overlapping structure for vacuum magnetic levitation. The tunnel overlapping structure comprises segment bodies for splicing a shield tunnel, circular seams of every two spliced segment bodies are connected by adopting a plug-in type quick connector, and longitudinal seams of every two spliced segment bodies are connected by adopting a slide-in type quick connector; and grouting holes and caulking seams are formed in the inner arc faces of the segment bodies, the adjacent segment bodies are fastened through the plug-in type quick connectors and the slide-in type quick connectors, and the structure is firm and easy to install.

Description

technical field [0001] The invention relates to the field of tunnel construction, more specifically, it relates to a tunnel superimposed structure for vacuum maglev. Background technique [0002] Due to the limitations of air resistance, wheel-rail friction, etc., it is difficult for wheel-rail transportation to achieve a substantial increase in operating speed economically under the existing technical level. The use of magnetic levitation technology to build a vacuum operating environment can reduce air resistance and noise, and meet the needs of higher economic operating speeds, that is, vacuum pipeline maglev transportation technology. The mechanical characteristics and fidelity maintenance of the pipeline structure are one of the key technologies for building a safe vacuum pipeline environment and developing high-speed transportation. On the other hand, my country has built a subway system with a long mileage. The development of vacuum maglev tunnel with tunnel segment l...
