Description
Technical field
The utility model belongs to that middle low speed magnetic suspension traffic engineering is low to put Line technology field, low more particularly, in
Fast magnetic floating traffic engineering two-wire embankment location support rail girder construction pattern.
Background technology
Middle low speed magnetic suspension track traffic belongs to a kind of novel traffic mode, and achievement in research both domestic and external is less, the whole world
The circuit for opening operation is even more minority.The middle low speed magnetic suspension railway business that only in March, 2005 Japan's construction at present is opened is transported
The middle low speed magnetic suspension railway business operating line that line-the East Hillside Line and in June, 2014 Korea open.And the middle low speed of China
Magnetic suspension traffic only National University of Defense technology's test wire, Green City Mountain test wire, Tangshan experiment line at present, but do not put into effect
Formal circuit, and based on elevated structure, the rarely seen relevant low research put in terms of circuit support rail girder construction and applies.
The outstanding traffic civil engineering part of middle low speed magnetic suspension mainly comprising bridge, it is low put circuit, station and rolling stock section, it is low to put circuit
