Description
Technical field
The utility model is related to technical field of rail traffic, more particularly to a kind of adjustable ballastless track structure and without the tiny fragments of stone, coal, etc.
Track.
Background technology
Non-fragment orbit has the advantages that high stability, few maintenance, long lifespan, at home and abroad urban rail, subway, Line for Passenger Transportation,
It is widely applied in the track traffics such as high-speed railway.Ballast track easily realizes orbit space geometric form by changing railway ballast
The adjustment of position, after current non-fragment orbit comes into operation, the adjustment of its space geometry morpheme is realized mainly by fastener, and is aided with to two
End line carries out vertical section fitting and optimized and revised, but the adjustment capability of fastener system is limited, typically heightens ability for 30mm, gauge
Adjustment capability is -12~+8mm.Even if if being adjusted using special tightening means for height-adjusting, the current maximum settlement amount of heightening can only achieve
56mm, it is overall to can adjust amount or limited even if coordinating the Profile Optimization adjustment into row line.In view of switch section backing plate
Particularity, such scheme is poor in track switch location applicability.In addition, after reaching and heightening the limit, to may in follow-up operation
The sedimentation of appearance can not carry out secondary adjustment.
Therefore, deformation of the non-fragment orbit to sub-rail foundation proposes very high request.Such as China Express Railway non-fragment orbit knot
