Description
Technical field
The utility model relates to high-speed railway slag-free rail construction technology, is specifically related to the gauge means for correcting in a kind of double-blocked rail without ballast construction.
Background technology
CRTS-I type double-blocked rail without ballast is in equipment Imported From German EMH Company radar 2000 technical foundation, in conjunction with China's national situation, through the domestic ballastless track system that innovation forms again, compares with the ballastless track of other form, has the advantages such as cost is low, work efficiency is high, good endurance.After Wuhan-Guangzhou passenger-dedicated line high-speed railway (design speed 350km/h) was formally open to the traffic in 2009, again at great Xi, Lanzhou and Xinjiang, Shanghai elder brother, the blue or green High-speed Passenger Dedicated Lines such as flourish, and the tunnel of growing up, station are applied to circuits such as hair lines.At present, CRTS-I type double-blocked rail without ballast has become one of main track form of China Express Railway.The core technology of CRTS-I type double-blocked rail without ballast system is: utilize tool track to fix prefabricated double-block type sleeper; Utilize three-dimensional control survey technology by the accurate space orientation of tool track; The cast-in-place railway roadbed board concrete of formwork erection is permanently affixed at double-block type sleeper in bed board, and then changes the long rail of paving formation gapless track, according to criterion of train running, circuit is carried out to later stage adjustment, opens operation after reaching the requirement of high ferro ride comfort.
At present, the construction technology of double-blocked rail without ballast is reaching its maturity aspect the control of the orbit parameters such as height, direction, all can meet design requirement and trueness error requirement.Have gauge parameter only and be subject to sleeper steel bar girder insufficient rigidity, the impact of the factors such as sleeper alignment error, the standard that has generally exceeded allowable error (± 1mm), have to rely on gauge strut to shore at a certain distance gauge, make it reach technical requirements, but this is only superficial phenomenon, adopt after gauge strut, in fact expanding by force after gauge, owing to shoring location gap large (every 3 sleepers are installed 1 gauge strut), cause sleeper track rail cant (standard is the 1:40 that slopes inwardly) to prolong line direction irregular variation occurs, the rail gradient that makes to lay after long rail is inhomogeneous, cause gauge suddenly big or suddenly small, rail level is distortion repeatedly, have a strong impact on safety and the comfort level of driving, height to track simultaneously, other parameter such as direction also has impact in various degree, must adjust fastener by a large amount of replacing, could meet the ride comfort requirement of high speed traveling.Therefore make fastener turnover rate conventionally up to more than 30%, engineering cost is high, simultaneously for being responsible for the reserved adjustment amount deposit wretched insufficiency of works department of circuit long-time maintenance after operation, totally unfavorable to the security of operation of high ferro and long-time maintenance.
Through a large amount of experimental studies, find, in work progress, gauge has an obvious Changing Pattern, i.e. the low impact of suspension truss rigidity is raised track after (section of track is built on stilts), and truss occurs lower rich, and tool track slopes inwardly, and gauge diminishes; Build after railway roadbed concrete, under the effect of chutable concrete buoyancy, the useful load acting on truss reduces, and under truss, the rich part that obtains is recovered; At concrete, possess after certain enabling capabilities, remove in time after section of track temporary supporting system, gauge thoroughly recovers.But being subject to the impact of man-made assembly section of track error, still there is irregular phenomenon in gauge.
Therefore, making full use of under the prerequisite of gauge Changing Pattern, while solving the man-made assembly section of track gauge irregular be the key of thoroughly improving double-blocked rail without ballast gauge parameter.
By the annexation of tool track and sleeper is studied to discovery, after sleeper is connected with tool track, between tool track and gauge block, gauge block and sleeper shoulder block, leave small gap (the about 0.2mm of width), each track place has 4 minim gaps (amounting to 0.7～0.8mm), the track at every sleepers two ends has the minim gap of 1.5mm left and right altogether, during the man-made assembly section of track, cannot guarantee the uniformity of each minim gap, sometimes tool track outwards pushes, cause outside minim gap closely connected, the corresponding increase of gauge, sometimes tool track inwardly pushes, cause inner side minim gap closely connected, gauge is corresponding to be reduced, the gauge inhomogeneities causing, with rich regular the dwindling after stack of gauge causing under truss, cause constructor to be difficult to judgement, if do not examined, usually cause error in judgement, when gauge is too small, for preventing that gauge from exceeding standard, blindly use strut expansion gauge, cause the change of sleeper rail cant, caused thus the irregularity of line direction, administer to later stage Track regularity and bring a lot of drawbacks, need to adopt the method for changing gauge block to adjust, result has strengthened workload, improved construction cost.
Summary of the invention
In view of double-blocked rail without ballast construction period is manually difficult to thoroughly eliminate sleeper alignment error, affect the conforming problem of gauge, the purpose of this utility model is to provide and a kind ofly can obviously improves construction precision, completely abolish gauge strut, and there is the means for correcting of the double-blocked rail without ballast gauge that work efficiency is high, cost is low.
