Description
Technical field
Line area is put the invention belongs to middle low speed magnetic suspension is low, more particularly, to middle low speed magnetic suspension traffic engineering
It is low to put circuit single line location support rail beam internode position limiting structure.
Background technology
Middle low speed magnetic suspension rail traffic belongs to a kind of novel traffic mode, and current achievement in research both domestic and external is less, entirely
The circuit that the world opens operation is even more minority.The middle low speed magnetic suspension railway quotient that only in March, 2005, Japan's construction was opened at present
The middle low speed magnetic suspension railway business operating line that industry runs line-the East Hillside Line and in June, 2014, South Korea opened.And in China
Low speed magnetic suspension traffic only has National University of Defense technology's test wire, Green City Mountain test wire, Tangshan experiment line at present, but without input fortune
The formal circuit of battalion, it is rarely seen in relation to the low research and application put in terms of circuit support rail girder construction and based on elevated structure.
In conventional general speed wheel rail railway, circuit is big to the adaptability of deformation, and phase is required to the settlement Control standard of roadbed
To more loose, thus there is a large amount of circuit to be built on fill subgrade；Current non-fragment orbit high-speed railway, although to roadbed under line
