Abstract
The invention discloses a prefabricated track plate structure capable of absorbing wheel track noise. The prefabricated track plate structure comprises a prefabricated plate. Steel tracks are arranged on the upper surface of the prefabricated plate. The prefabricated plate is integrally arranged in a groove of a base platform. An anti-vibration pad is arranged between the prefabricated plate and the groove of the base platform. A noise absorbing plate is further arranged in the position, between the steel tracks, of the upper surface of the prefabricated plate. The noise absorbing plate is made of porous spherical particles. The two sides of a base body are provided with retaining walls. Thus, the prefabricated track plate structure capable of absorbing the wheel track noise is simple in structure, the vibration damping requirement and the noise reduction requirement are both met, the demand for the strength is also met, and meanwhile the firefighting evacuating function is achieved.
Description
Technical field
The present invention relates to the track structure vibration and noise reducing field of track traffic, particularly relate to a kind of prefabricated track plates structure having and absorbing wheel-rail noise.
Background technology
In track traffic train operation, due to guideway irregularity, wheel out of round along etc. reason, make between wheel track produce vibration, this partial vibration is transferred to railway roadbed from rail successively, it is delivered to civil engineering structure again, then to the structure periphery soil body, transmission and consumption in above-mentioned different structure and medium.
Damper rail is usually and adopts in track structure bottom flexible member to be separated with infrastructure by track plates, thus the transmission reduced between vibrational energy lower portion basis. After have employed damper rail, the partial vibration energy demand originally passing to tunnel structure consumes by increasing the vibration of road bed board, thus bringing the noise of low frequency, due to the narrow space in tunnel, this part acoustic energy needs could eliminate through reflection repeatedly, refraction, resonance. So at train through damper rail location, internal car noise can substantially increase, the especially noise of low frequency, cause that comfort of passenger reduces.
For this, the designer of the present invention is because the problems referred to above, and by concentrating on studies and designing, comprehensive experience and the achievement being engaged in related industry for a long time for many years, research design goes out a kind of prefabricated track plates structure having and absorbing wheel-rail noise, to overcome drawbacks described above.
Summary of the invention
It is an object of the invention to provide a kind of prefabricated track plates structure having and absorbing wheel-rail noise, it is provided with vibration and noise reducing structure in track plates, overcomes the defect of prior art, high practicability.
For solving the problems referred to above, the invention discloses a kind of prefabricated track plates structure having and absorbing wheel-rail noise, comprise precoated plate, the upper surface of described precoated plate is provided with rail, and described precoated plate is wholy set in the groove of a base station, it is characterised in that:
It is provided with vibration damping bed course between described precoated plate and the groove of base station, between precoated plate and rail, is provided with labyrinth type sound absorption structure.
Wherein: the centre at described cushion blocking interval between described groove and precoated plate, and the two ends at interval are provided with sealing device.
Wherein: described cushion blocking comprises substrate and the vibration damping projection upwards arranged from substrate in array, and the preferred cone rubber material of described cushion blocking or microporous polyurethane expanded material are made, and its face rigidity is 0.005～0.2N/mm3, to meet rigidity and the requirement of strength of vibration damping.
Wherein: the upper surface of described precoated plate is additionally provided with sound absorption structure between rail, described sound absorption structure adopts porous spherical granule to make, and the diameter of described porous spherical granule is preferably 2-18mm.
Wherein: described matrix both sides are provided with barricade.
By said structure it can be seen that the prefabricated track plates structure absorbing wheel-rail noise that has of the present invention has the effect that
1, simple in construction, had both met vibration damping demand, met again noise reduction demand, also met strength demand, was provided simultaneously with the function of fire-fighting evacuation.
2, sound absorption structure and vibration-proof structure can realize once-combined molding, and operation simplifies, and make simple.
3, cushion blocking is beneficial to draining, with low cost.
The detailed content of the present invention can be obtained by explanation described later and institute's accompanying drawing.
