Description
Technical field
The utility model relates to that medium-and low-speed maglev traffic is low puts line construction technical field, to refer in one that low speed magnetic suspension is low particularly and puts circuit continuous frame formula support rail girder construction.
Background technology
Middle low speed magnetic suspension track traffic belongs to a kind of novel traffic mode, and current achievement in research both domestic and external is less, and the circuit minority especially of operation is opened in the whole world.In March, 2005 Japan is only had to build middle low speed magnetic suspension railway comercial operation line-the East Hillside Line of opening and middle low speed magnetic suspension railway business operating line that in June, 2014, Korea S opened at present.And the middle low speed magnetic suspension traffic of China only has National University of Defense technology's test wire, Green City Mountain test wire, Tangshan experiment line at present, there is no the circuit formally put into effect.
The low circuit of putting of medium-and low-speed maglev traffic engineering is made up of roadbed under sleeper, support rail beam and support rail beam, and the support rail beam of supporting track is arranged on by the roadbed that earth structure is formed.For in the existing research of magnetic floating traffic engineering, more to the research of bridge rail beam, as all there is the rail beam of complete web the both sides such as prestressed reinforced concrete case beam, U-shaped beam, i beam.And it is little for low research of putting circuit support rail beam, existing research focuses mostly in buttress supporting construction, and as " routine conductive maglev pier bearing structure of train design search ", (article is numbered: 1006-2106 (2006) 07-0041-05).
Existing bridge rail beam is that frame stands between two bridge piers, by simply supported beam or Continuous beam design, is satisfied distortion and stability requirement, and its physical dimension is general very large, obviously can not be directly used in low putting on circuit.Existing bridge rail beam mostly is both sides and has the structures such as the case beam of complete web, U-shaped beam, i beam, the advantages such as the rail beam of this several structure, all has good stability, and rigidity is large.Low wiring board support rail of putting also makes the structures such as case beam, U-shaped beam, i beam with reference to bridge rail beam, is placed on the road bed of ground composition, then aobvious outward appearance is heavy, also unsightly; In addition, the space between web is very little, and personnel cannot carry out inspection and maintenance operation to it, and in two-wire location, and between line, water can not transverse in-line, must online between gutter is set.
Existing buttress type support rail beam, sleeper pedestal is arranged on buttress top, is born the load of track structure transmission by buttress, strengthens the stable of structure by the longitudinal and transverse binder at its top.Buttress type support rail beam has portable construction, and in two-wire location, between line, water can the advantage such as transverse in-line, but also there is following problem:
1, because sleeper pedestal is arranged on buttress top, thus, the sectional dimension of buttress, can not be less than sleeper pedestal.The position of buttress must be determined according to sleeper position, requires that construction control precision is high, and especially at 3 in Curve Segment, the construction positioning difficulty of buttress is larger.
2, for increasing the rigidity of buttress and the ability of resistance to deformation, prop up socle and be often provided with longitudinal and transverse binder, for saving engineering quantity, the sectional dimension of these longitudinal and transverse binders is less than the sectional dimension of buttress more, in construction, is difficult to make integral mold plate, buttress and longitudinal and transverse binder carry out monobloc cast, need first construct buttress more longitudinal and transverse binder of constructing, working procedure is many.
3, by the buttress type support rail beam of beam on elastic foundation design, top buttress is arranged on the armored concrete slab under it mostly, and its integral rigidity is little, and in lifting, transportation, structure is yielding, prefabrication mode should not be adopted to construct, answer field cast-in-place to construct.
