Description
Technical field
The invention belongs to ballastless track of high-speed railway structure repair technical field, and in particular to one kind is for settling roadbed
CRTSI plate-type non-fragment orbit lifting method for correcting error.
Background technology
Non-fragment orbit is a kind of reduced-maintenance track structure, and it replaces ballast aggregate using reinforced concrete footing plate, by wheel track
Power is distributed and is delivered on foundation of road bed.Non-fragment orbit has good track stability, continuity and ride comfort, service life
Long, structure durability is good, and the features such as maintenance load is few, therefore most of our high-speed railways built at this stage are with without tiny fragments of stone, coal, etc. rail
Based on road.The rigidity of non-fragment orbit is very big, causes its plastic deformation small.The sinking once basis below track deforms, repaiies
Multiple difficulty, improved possibility is restricted.When the basis of non-fragment orbit bottom occurs uneven sedimentation, may result in
Non-fragment orbit circuit shifts on roadbed.When side-play amount exceedes certain value, it will have a strong impact on the safety of train driving
Property, comfortableness and ride comfort.Because track panel stiffness is big, adjustment capability is poor, when there is track irregularity, it is difficult to as there is tiny fragments of stone, coal, etc. rail
Road equally adjusts the skew of rail height and level by changing railway ballast thickness, making the means such as railway ballast firm by ramming.
Traditional is to adjust rail using adjustment fastener system to non-fragment orbit Track Settlement skew restorative procedure on roadbed
Road height and level, but the adjusted value that rail height and horizontal offset are adjusted with fastener system is limited, when deviant is big
The effect of fastener system is limited when its adjusting range.When using " one kind is entangled for settling non-fragment orbit midline shift
Folk prescription method " (201410394616.1), the method is directly using the slip-casting lifting correction in roadbed, the now difficult control of lifting correction amount
System, the ride comfort on track plates can produce influence, and chemical pulp is noted in addition has change to roadbed material characteristic.When using " for soft
The method for correcting error of soil area ballastless track of high-speed railway roadbed " (201410070311.5), the method makes roadbed there occurs movement,
Change soil structures proterties and be only adapted to soft clay area.
The invention provides CRTSI plate-types non-fragment orbit lifting deviation correcting device and method on a kind of high-speed railway subgrade,
Using installing lifting frock on bedplate, using hydraulic system by bedplate (including track above plate) entirety lifting, flat
Move, solve the problems, such as that fastener system adjusted value is limited, can be in high-speed railway Window time to non-fragment orbit circuit on roadbed
Sedimentation skew disease completes to repair and ensure the ride comfort of circuit.
