Description
Technical field
The utility model relates to urban track traffic, particularly a kind of urban track traffic track structure suppressing ripple to grind.
Background technology
In urban track traffic, because being subject to urban architecture, passing round the impact of the factors such as pile foundation, curve circuit design radial is less, minimum only about 300m, after new steel rail laying uses, along with the raising of passenger flow, the increasing of vehicle density, small radius location rail contact surface has slowly occurred resembling undate uneven wear, i.e. Rail corrugation (being called for short ripple mill).
The existence of rail corrugation will cause the vibration of vehicle, track structure fierceness, produces noise, affects passenger's ride quality, too increase maintenance load and the maintenance cost of maintenance department, and serious rail corrugation may cause the generation of great derailment accident.
One of technical problem that Bo Moshi railway circle does not thoroughly solve so far.People are to its observation and study oneself and have history for many years.Although people are by theory and numerical method is initially formed rail corrugation and the understanding of development mechanism has had very large progress, a kind of effective theoretical model of unification of extensive approval is not also had to grind initial formation mechenism to explain ripple and affect the factor that ripple grinds development up to now.
Railway track is longitudinally supported on railway roadbed and roadbed, bridge, tunnel by each sleeper, and like this, rail is discrete support, then vertical the and lateral stiffness of track and impedance are longitudinally uneven, are into periodically variable.Find according to a large amount of theoretical researches, the discrete support of sleeper or the impact of sleeper pitch on the initial formation and development of rail corrugation are one of very important factors.Also find according to on-the-spot a large amount of investigation both at home and abroad, ripple mill mainly appears on the rail in the middle of every two sleepers, and its vibration frequency is generally sleeper pitch/speed of service.
Relevant railway department was by test afterwards, inserted a sleepers between two sleepers, found that this ripple mill makes moderate progress.Be also propose a kind of method in " the railway track with small-radius curve system that ripple can be suppressed to grind " Patent Prospectus in application number 201210571888.5, denomination of invention, between the bottom surface of rail at sharp radius curve bend place between sleeper and railway roadbed, hydraulic buffer is installed, the vibration of wheel track is decayed, thus slows down rail corrugation generation.But said method is only experimental study use, by the restriction of track structure and maintenance condition, as comparatively difficulty will be promoted the use of.
Simultaneously, the shield tunnel of city urban track traffic as Yangtze River Delta cities such as Shanghai, Hangzhou, Ningbo inevitably passes through soft soil layer location, along with the long term accumulation of train operation vibrational excitation effect, all occurred tunnel subsidence phenomenon in various degree, settling amount can reach more than 50mm.Especially at the service channel place in tunnel; general employing freezing process; namely along the freezing hole that excavated section periphery is substantially parallel with service channel direction; then circulate hypothermic saline in freezing hole; water bearing ground near freezing hole is frozen; form the Frozen Soil Cylinder that intensity is high, water shutoff is good, under the protection of Frozen Soil Cylinder, carry out passage boring construction.After treating service channel main structure construction, stop cooling, the soil body thaws naturally, can cause the sedimentation in tunnel near service channel in course of defrosting, and settling amount often can reach more than 100mm.These sedimentations will cause track irregularity, affect traffic safety.Sedimentation in a small amount, by rail clip reparation, once settling amount exceedes the adjustment capability (generally the maximum amount of heightening is 30mm) of fastener, just needs to carry out regulation reparation to ballast bed of track, could meet the requirement of orbital forcing.Railway roadbed regulation is long for repair time, and inconvenient maintenance, maintenance cost is high, even affects the normal operation of train.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of urban track traffic track structure suppressing ripple to grind, and with adjustable problem after effectively solving rail corrugation and sedimentation, is conducive to keeping orbital forcing, facilitates the maintenance of track.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
A kind of urban track traffic track structure suppressing ripple to grind of the present utility model, basic under comprising pre-stress rail plate, rail and line, pre-stress rail plate to be layed under line on basis, rail is fixed on pre-stress rail plate by fastener system, it is characterized in that: described pre-stress rail plate flushes with pre-stress rail plate upper face in the support rail face of fastener for installing position; Arrange continuous rubber pad placed under-neath rail between described rail foot surface and pre-stress rail plate upper face, continuous rubber pad placed under-neath rail extends continuously along line direction; Arrange regulatable supporter between basis under described pre-stress rail plate lower face and line, regulatable supporter is along line direction and be horizontally arranged at interval.
The beneficial effects of the utility model are, adopt pre-stress rail plate, flush with pre-stress rail plate plate face between two fasteners in the support rail face of fastener for installing position, then under rail, continuous rubber pad placed under-neath rail is laid, rail support stiffness is continuous, regulatable supporter is adopted to support under track plates, by adjusting the rigidity of regulatable supporter, with with continuous rubber pad placed under-neath rail Rigidity Matching, can avoid producing the Short wave irregularity that wavelength is rail fastening gap length, also just eliminate the wheel track Forced Frequency of this wavelength, thus reduce the ripple mill of rail; Can establish adjustment pad under continuous rubber pad placed under-neath rail, what regulatable supporter supported all can establish adjustment pad up and down, therefore has the very large amount of heightening; Maintenance is convenient, the time is short, can complete the maintenance of track, do not affect normal operation in operation maintenance Window time.
