Description
Technical field
The present invention relates to engineering field, particularly relate to a kind of rubber spacer railway structure with vibration and noise reducing function.
Background technology
Continuous expansion along with China's city size, the strongest to the growth requirement of public transport, occurring in that the most newly-built transit's routes on city map, urban track traffic, as the most effective way of alleviation urban traffic pressure, had obtained swift and violent development in recent years.The version that current track traffic uses mainly has slab track structure, trapezoidal track structure, sleeper track structure.
Slab track globality is relatively good, and it there is the problem that concrete usage amount is relatively big, and construction costs is higher, and dead weight is relatively big simultaneously, especially for use in time on bridge, adds the deadweight of bridge top；In order to ensure the security of bridge, on bridge, other sectional dimension of members also to increase therewith, adds the cost of bridge itself accordingly.
Trapezoidal track structure has the advantage of lightness, and is easy at trapezoidal track damping element disposed below, its there is the problem that trapezoidal track structure use during the most cracking situation of connecting portion at trapezoidal track connecting rod two ends.Cracking reason mainly due to track when train passes through, the problem such as track irregularity, cause train to there is oscillation crosswise, and the connecting rod of trapezoidal track be located in the track girder centre position along short transverse.Under the effect of rail level cross force, the rod end of connecting rod produces Moment.Less due to the sectional dimension of connecting rod again, resist torque ability is the most weak, and then plastic hinge occurs in the end in connecting rod.When plastic hinge Stiffness Deterioration is more serious, the constraint rigidity that connecting rod is horizontal to track girder will be affected, jeopardize the traffic safety of train.
Sleeper track structure there is the problem that structure comparison disperses, and is unfavorable for that factory is integral prefabricated, is unfavorable for the layout of damping element.
Additionally, architecture ensemble in the past is the most sparse, the vibration that rail traffic vehicles causes does not becomes problem of concern to the impact of surrounding environment；And it is present, fast development along with urban construction, elevated rail traffic, Underground Rail Transit, rail on ground traffic gradually from underground, ground and be progressively deep into residential area, commercial center and industrial area intensive city in the air, the environmental problem that track traffic causes is more and more significant.For being chronically at the building in closely vibration and noise circumstance, and they internal residents and the work of staff and life, create the biggest impact.
Being in particular in: on the one hand along with the increase of volume of transport, ambient vibration problem is day by day serious, and on the other hand, people are more and more higher to the requirement of quality of life, and the ambient vibration problem that track traffic causes more and more causes the kickback of the public.Noise reduction technology is used in the construction of rail line, eliminate society's complaint of the ambient vibration initiation that track traffic causes as far as possible, making subway nearby residents satisfied, building the quiet track traffic of environmental protection will be demand and the inexorable trend of social harmonious development of people.Therefore, it is necessary to existing track beam structure is improved, to solve the problems referred to above.
