Embodiment Construction

[0020] see figure 1 , showing the prefabricated track slab structure of the present invention with absorbing wheel-rail noise.

[0021] The prefabricated track slab structure with absorbing wheel-rail noise comprises a prefabricated slab 11, the structure and shape of the prefabricated slab 11 can be of a conventional type, the upper surface of the prefabricated slab 11 is provided with a steel rail 12, and the prefabricated slab 11 11 is integrally arranged in a groove of a base 13 , and a vibration damping pad 14 is provided between the prefabricated plate 11 and the groove of the base 13 .

[0022] Vibration between the prefabricated slab 11 and the abutment is eliminated comprehensively through the setting of the vibration damping pad 14. Optionally, the vibration damping pad 14 is located in the middle of the interval between the groove and the prefabricated slab 11, The two ends of the interval are provided with sealing devices to avoid the entry of external rainwater o...

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 [0001] The invention relates to the field of vibration and noise reduction of track structures of rail transportation, in particular to a prefabricated track plate structure capable of absorbing wheel-rail noise. Background technique [0002] During the operation of rail transit trains, vibrations are generated between the wheel and rail due to reasons such as uneven lines and uneven wheels. This part of the vibration is transmitted from the rail to the ballast bed, then to the civil structure, and then to the soil around the structure. Delivered and consumed in the different structures and media mentioned above. [0003] The damping track generally uses elastic elements in the lower part of the track structure to separate the track plate from the lower foundation, thereby reducing the transmission of vibration energy to the lower foundation. After adopting the damping track, part of the vibration energy originally transmitted to the tunnel structure needs t...
