Description
Technical field
The present invention relates to urban track traffic, more particularly to a kind of urban track traffic track structure for suppressing ripple to grind.
Background technology
In urban track traffic, because by urban architecture, passing round the factors such as pile foundation and being affected, curve circuit design radial is less, minimum only 300m or so, after new steel rail laying use, with the raising of passenger flow, the increasing of vehicle density, minor radius location rail contact surface is slowly occurred in that as undate uneven wear, i.e. Rail corrugation (abbreviation ripple mill).
The vibration that the presence of rail corrugation will cause vehicle, track structure fierce, produces noise, affects passenger's ride quality, also increases the maintenance load and maintenance cost of maintenance department, and serious rail corrugation may cause the generation of great derailment accident.
Bo Moshi railways circle are so far without one of thorough technical problem for solving.People are to its observation and study oneself and have history for many years.Although rail corrugation is initially formed by theoretical and numerical method for people and the understanding of development mechanism has very big progress, explain that ripple mill is initially formed mechanism and affects the factor of ripple mill development so far also without a kind of effective theoretical model of unification of extensive approval.
Railway track is to lean on each sleeper along longitudinal supporting on railway roadbed and roadbed, bridge, tunnel, and so, rail is discrete support, then the vertical and lateral stiffness of track and impedance is uneven along longitudinal direction, is into periodically variable.Found according to substantial amounts of theoretical research, the discrete support of sleeper or sleeper pitch is initially formed to rail corrugation and the impact that develops is one of very important factor.According to the substantial amounts of investigation in domestic and international scene, it was also found that ripple mill is mainly appeared on the rail in the middle of every two sleeper, its vibration frequency is generally sleeper pitch/speed of service.
Later relevant railway interests inserted a sleepers by test between two sleepers, it is found that this ripple mill makes moderate progress.It is also proposed that a kind of method in application number 201210571888.5, entitled " the railway track with small-radius curve system that ripple can be suppressed to grind " Patent Prospectus, hydraulic buffer is installed between the bottom surface and railway roadbed of the rail between sleeper of sharp radius curve corner, the vibration for enabling wheel track decays, and occurs so as to slow down rail corrugation.But said method is only that experimental study is used, and is limited by track structure and maintenance condition, such as to promote the use of more difficult.
Simultaneously, the shield tunnel in the city urban track traffic such as Yangtze River Delta city such as Shanghai, Hangzhou, Ningbo inevitably passes through soft soil layer location, with the long term accumulation that train operation vibrational excitation is acted on, different degrees of tunnel subsidence phenomenon is occurred in that, settling amount is up to more than 50mm.Especially at the service channel in tunnel; typically adopt freezing process; arrange the freezing hole substantially parallel with service channel direction along excavated section periphery; then hypothermic saline is circulated in freezing hole; the aquifer water-bearing stratum near freezing hole is set to freeze; formation intensity is high, the Frozen Soil Cylinder that water shutoff is good, and row of channels boring construction is entered under the protection of Frozen Soil Cylinder.After service channel main structure construction is finished, stop cooling, soil body naturally to thaw can cause the sedimentation in tunnel near service channel, settling amount to tend to reach more than 100mm in course of defrosting.These sedimentations will cause track irregularity, affect traffic safety.The sedimentation of a small amount of can by rail clip reparation, once settling amount exceedes the adjustment capability (the general maximum amount of heightening be 30mm) of fastener, it is necessary to regulation reparation is carried out to ballast bed of track, the requirement of orbital forcing could be met.Railway roadbed regulation repair time is long, and inconvenient maintenance, maintenance cost is high, or even affects the normal operation of train.
The content of the invention
The technical problem to be solved is to provide a kind of urban track traffic track structure for 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.
The technical solution adopted for the present invention to solve the technical problems is as follows：
A kind of urban track traffic track structure for suppressing ripple to grind of the present invention, including basis under pre-stress rail plate, rail and line, pre-stress rail plate is layed under line on basis, and rail is fixed on pre-stress rail plate by fastener system, be it is characterized in that：The pre-stress rail plate is flushed in the support rail face of fastener for installing position with pre-stress rail plate upper face；Continuous rubber pad placed under-neath rail is set between the rail foot surface and pre-stress rail plate upper face, and continuous rubber pad placed under-neath rail continuously extends along line direction；Regulatable supporter is set under the pre-stress rail plate lower face and line between basis, and regulatable supporter is along line direction and is horizontally arranged at interval.
The invention has the beneficial effects as follows, using pre-stress rail plate, pre-stress rail plate plate face is flushed between the support rail face of fastener for installing position and two fasteners, then continuous rubber pad placed under-neath rail is laid under rail, rail support stiffness is continuous, supported using regulatable supporter under track plates, by the rigidity for adjusting regulatable supporter, with with continuous rubber pad placed under-neath rail Rigidity Matching, can avoid producing Short wave irregularity of the wavelength for rail fastening gap length, also the wheel track Forced Frequency of the wavelength is eliminated the need for, so as to the ripple for reducing rail grinds；Adjust pad can be set under continuous rubber pad placed under-neath rail, what regulatable supporter was supported can set up and down adjust pad, therefore with the very big amount of heightening；Maintenance is convenient, the time is short, and the maintenance of track can be completed in operation maintenance Window time, does not affect normal operation.
