Lowly arranged wire structure used in medium-low speed magnetic levitation traffic engineering fill section

Abstract

The invention belongs to the technical field of medium-low speed magnetic levitation traffic engineering, and in particular to a lowly arranged wire structure used in a medium-low speed magnetic levitation traffic engineering fill section. The lowly arranged wire structure comprises bearing rail beams, a soil filling roadbed structure and internode mistake-proofing bedplates, wherein the bearing rail beams comprise track and guide track bearing structures and bottom plates; a gap is formed between every two adjacent bottom plates; a lower bearing rail beam pad layer is arranged between the bottom surface of each bearing rail beam and the top surface of the soil filling roadbed structure; the internode mistake-proofing bedplates are arranged at the bottom of the gaps between adjacent bottom plates and are positioned between adjacent lower bearing rail beam pad layers; bearing rail beam refilling protection layers are arranged on the top of the soil filling roadbed structure; waterproof sealing layers are arranged on the surfaces of the bearing rail beam refilling protection layers; evacuation platforms and auxiliary construction connector systems are arranged on the tops of the bearing rail beam refilling protection layers. The lowly arranged wire structure can meet the requirements of stable operation of a magnetic-levitation train, is sufficient in strength and deformation resistance, and can ensure long-term stability of a roadbed main body below the bearing rail beams in various natural environments.

Description

technical field [0001] The invention belongs to the technical field of medium and low-speed magnetic levitation traffic engineering, and in particular relates to a low-set line structure used for filling sections of medium-low speed magnetic levitation traffic engineering. Background technique [0002] In conventional normal-speed wheel-rail railways, the lines have great adaptability to deformation, and the requirements for subgrade settlement control standards are relatively loose, so a large number of lines are built on filled subgrades; the current ballastless track high-speed railways, despite the The post-construction settlement control requirements of the subgrade are very strict, and there are still many lines built on the filled subgrade. The subgrade under the line is required to be built according to the structure, with sufficient strength and deformation resistance, and long-term stability in various natural environments. However, the maglev trains of the medium ...

Problems solved by technology

[0003] In the current research on maglev traffic engineering and related technical standards or provisional regulations, the low-set structure is defined as "the line structure with the bottom of the track beam close to the ground line and between the elevated line and the underground line", and requires " The embankment form should not be used for medium and low-speed maglev traffic subgrade projects”; in addition, the operation mode, track structure, power supply mode, and functional requirements of maglev traffic projects are different from those of wheel-rail railways. The layout of the subsidiary structures is different. Therefore, the subgrade structure of the high-speed railway cannot be applied to the maglev traffic project, and there are few studies and applications on the installation of the maglev low-lying line on the low-lying line in the filling section.
