The track structure of bridge.
Background technology
Non-fragment orbit refers to the track knot for replacing shot ballast bed using mass-type foundations such as concrete or asphalts
Construction system, sleeper are formed by concreting in itself.China uses till now in a large number from first bar Ballastless Track Experimental Section, so far
More than 10 years, also present III template of CRTS has been developed into from I template of CRTS, II template of CRTS in version, except these
Also streamed just like non-master such as monoblock type road bed board outside classical field formalism.
With respect to the development of non-fragment orbit, the railroad bridge for carrying basis as non-fragment orbit does not have too big tune
Whole, the railroad bridge of prior art is generally only that corresponding adjustment secondary dead load is matched.For changing in the interaction of beam rail
If philanthropist's track is in effort, the actual scale of construction for getting on the right track all too for bridge is little, is improving the relation between two
On be no doubt that to be conceived to big person more effective.
Though existing non-fragment orbit technology has many advantages, bridge does not inherently carry out interaction, simply on load
Reflect, so also there are some shortcomings：1st, non-fragment orbit cost is high, can only be from having with respect to the economic benefit of Ballast track
Tiny fragments of stone, coal, etc. track needs increased maintenance cost to obtain, and this point be supported seldom by the dimension of non-fragment orbit premised on；2nd, concrete nothing quarrel
Track is rigid bearing bed, will produce fracture when the bearing strength limit is reached, and causes the suddenly change of Rail inspection；
3rd, there is the deficiency of nature in non-fragment orbit to the adaptability for lifting the temperature difference, and such as terminal spine is easily cut up, and is difficult to overcome.
Engineering disease problem is the ripe necessary process of new technology, and actual improving countermeasure is also in process always.For
The railroad bridge non-fragment orbit of prior art, the construction under existing rail between back are excessively complicated, multiple multiple between layers
The systematic function discreteness brought by miscellaneous and unstable contact relation is necessarily bigger than normal, can if deviation is beyond preset range
Cause engineering disease, this is sure.
