Description
Technical field
The utility model relates to ballastless track of high-speed railway, particularly a kind of ballastless track on bridge structure.
Background technology
Existing ballastless track on bridge structure is divided into vertical linking-board type, the unit is board-like and three kinds of two piece sleeper flush types; Wherein the unit is board-like adopts segmented base and track plate or road bed board with the double-block type ballastless track structure on bridge; 5～7m is provided with the shrinkage joint of a disconnection, and base and bridge are consolidated into one.Because bridge and rail are along with the active force of the variation generation of external conditions such as temperature; Can produce considerable influence each other; Therefore calculate under the situation about can't pass through in the inspection of gapless track beam rail active force at special long-span bridge, must adopt rail overlapping device to discharge the active force between the beam rail.The setting of rail overlapping device can have a strong impact on the stationarity and the comfortableness of driving again, and the speed that hinders train simultaneously promotes, so in the railroad track design, all avoid being provided with rail overlapping device as far as possible.And vertical linking-board type non-fragment orbit adopts beam rail isolating construction; Bridge is separated with the rail active force with the active force that conditions such as ambient temperature produce; Influencing each other between the beam rail can be reduced greatly, rail overlapping device can be cancelled thereby on the speciality bridge, lay.
But owing to indulge all more complicated of the design of linking-board type non-fragment orbit, construction technology; And investment is high than other non-fragment orbit structure; So present many rail tracks all adopt the double-block type ballastless track structure; Special long-span bridge (particularly mountain railway) is arranged in these circuits unavoidably, if still adopt double-block type ballastless track, then inevitably wanting the steel rail laying expansion and cotraction regulator or adopting has tiny fragments of stone, coal, etc. track structure.If only on a bridge, lay vertical linking-board type non-fragment orbit, all can bring many difficulties then for design, construction, operation maintenance, and increase bigger investment.
The utility model content
The utility model technical problem to be solved provides a kind of ballastless track on bridge structure, applies to the special bridge of growing up and can reduce beam rail active force greatly, keeps the unity of track structure completely.
It is following that the utility model solves the technical scheme that its technical problem adopted:
A kind of ballastless track on bridge structure of the utility model; From bottom to top comprise bridge beam body, reinforced concrete footing, steel concrete road bed board; It is characterized in that: said reinforced concrete footing is the overall structure along the continuous cast-in-place formation of overall length of bridge; The bridge beam body top is provided with the sliding layer platform, between reinforced concrete footing bottom surface and sliding layer platform end face, lays sliding layer; Said steel concrete road bed board is imbedded prefabricated sleeper member by constituting along the cast-in-place segmented road bed board that forms of overall length of bridge segmentation in segmented road bed board; Said reinforced concrete footing, segmented road bed board connect through connecting elements, perhaps are provided with location structure; The fixed end of said bridge beam body, reinforced concrete footing is fixed through syndeton and bridge beam body; Said reinforced concrete footing, bed board direction across bridge both sides, segmented road are provided with the spacing member that limits its direction across bridge displacement on bridge beam body.
The beneficial effect of the utility model is; Utilization both can reduce beam rail active force greatly on the special bridge of growing up; Keep the unity of track structure completely, make things convenient for design, construction and operation management greatly, can save construction investment than laying vertical linking-board type non-fragment orbit simultaneously.
