Description
Technical field
The utility model is related to non-fragment orbit fields, more particularly to a kind of position limiting structure of non-fragment orbit.
Background technology
Ending for the end of the year 2016, China express railway operating mileage is more than 2.2 ten thousand kilometers, and China has become in the world at present
High-speed railway operation overall trip speed is most fast, operating mileage longest, the maximum country of building scale.China express railway track structure
Ballastless track structure form is mainly used, using the in the majority of plate-type ballastless track form wherein in non-fragment orbit, major families have
I types of CRTS, II type and III plate-type non-fragment orbit etc..
Field research shows under the repeated action of train load and temperature load, plate-type ballastless track multilayer structure making
Stress deformation, state parameter of system etc. relative to design at the beginning of changed, disease occurrence frequency, type is more and more, example
Gap disease problem such as between track plates arch, quadrangle buckling deformation and screed and base board, track plates.Multilayer track
Structure causes temperature stress in track plates to be unevenly distributed under Complex Temperature ringing, causes the concrete at plate seam
Repeatedly tension and compression stress and it is damaged, track plates arch up.In addition, when bed joint quality dissatisfaction or it is defective when, can cause
There is interlayer gap in track structure, aggravation track plates arch, make track plates be difficult keep vertically and horizontally with vertical track geometry.One
Denier track plates cannot keep its track geometry, and upper part structure rail will be caused irregularity, the appearance of Rail irregularity occur
It is light then lead to train speed limit, it is heavy then lead to safety accident.
Currently, for the limit problem of track plates, studies in China has proposed some limit measures, and there are commonly track plates ends
Implantation position-limitting pin pours track plates and laterally withholds block etc..But track plates end is implanted into position-limitting pin commonly used in arch disease
Passive regulation, the quantity for being implanted into pin is larger and indefinite, due to track plates arch gap be happened at summer high-temperature season, plant
Muscle scheme easily causes track plates tension hurt under worst cold case；Track plates laterally withhold the entirety that block affects track structure
Aesthetics so that total seems redundancy, and is limited by construction condition and place, and the concrete poured withholds block
Also easily cracking, damaged etc. the secondary disease under Complex Temperature load action.
Accordingly, it is desirable to provide a kind of limiting device or structure for track plates limit, can effectively limit track
Vertically and horizontally and vertical deviation, and there is certain adjustment effect, prevents the generation of secondary disease.The utility model proposes one kind
Grout hole is implanted into the position limiting structure of rod iron, solves problem above well；And relative to existing limit measure, has and apply
The advantages that work is simple, stress is clear, solid and reliable, cost is relatively low, and existing rail can be repaired as passive limit measure
The problems such as guidance tape arch, interlayer gap, and track structure optimization design can be used for as a kind of new track structure limit method
In.
