Description
Technical field
This utility model belongs to support rail beam field, puts line more particularly, to a kind of middle low speed magnetic suspension traffic engineering is low
Road solid support rail girder construction.
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 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 S will open.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, there is no formal input
The circuit of operation.
Middle low speed magnetcisuspension suspension traffic civil engineering partly mainly comprise bridge, low put circuit, station and rolling stock section, low put circuit
It is made up of roadbed under the section of track, support rail beam and support rail beam, the support rail beam of supporting track is arranged on the roadbed being made up of earth structure

On base plate, its integral rigidity is little, in lifting, transportation, the yielding cracking of structure, and should not be applied using prefabrication mode
Work, can only be confined to field cast-in-place construction.
(3) Maglev Project track structure be located at support rail beam on, track structure can carry out small range be adapted to magnetic float
The requirement of train, but its adjustment degree is with grade precision controlling, so requiring and track requirement for meeting line position, support rail beam
Construction must controllable precise.But buttress type support rail beam is very many due to primary structural component, it is using cast-in-place form of construction work simultaneously, its
Construction precision is difficult to control, the driving safety of this construction quality directly influencing track and train.
(4) upper track version is limited to the structure of buttress type support rail beam, section of track arrangement can not arbitrarily put it is necessary to
Accurately arranged according to the position of buttress, structure transverse width.This increases difficulty for construction, especially in 3 in Curve Segment enforcement difficulty
Bigger.
(5) upper track version does not consider the temperature impact that field colds and heat succeed each other under the conditions of environment etc., easily deforms
With crack, there is potential safety hazard.
