DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the train operation system of the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] like Figure 1 、 2As shown, a train operation system comprises a ground section 2, a transition section 3, and a tunnel section 4, arranged in sequence along the extension direction of a track 1. The transition section 3 comprises a first wall 5, a second wall 6, and a cover plate 7. In a direction perpendicular to the extension direction of the track 1, the first wall 5 and the second wall are located on either side of the track 1, with their bottom ends fixedly connected to the ground surface on which the track 1 rests, and their top ends freely extending upward. The cover plate 7 has its ends fixedly connected to the top ends of the first wall 5 and the second wall 6, respectively. Together, the first wall 5, the cover plate 7, and the ground form an operating space 12 through which the track 1 passes. Along the extension direction of the track 1, one end of the first wall 5, the second wall 6, and the cover plate 7 are fixedly connected to the tunnel lip of the tunnel section 4, and the other ends extend toward the ground section 2. This technical solution can confine the noise generated by a train passing through the tunnel within the operating space 12, attenuating it within the operating space 12 before being transmitted outside, effectively controlling noise pollution to the surrounding environment. In actual production, the first wall 5 and / or the second wall 6 and / or the cover plate 7 are all integrally cast by concrete.

[0028] As an optional implementation, Figure 2 As shown, the invention further includes a first sound-absorbing component 8 and a first baffle 9. A first accommodating space 10 is defined within the first wall 5. The first sound-absorbing component 8 is disposed within the first accommodating space 10. The first accommodating space 10 forms a first opening (not shown) on the surface of the first wall 5 facing the second wall 6. The first baffle 9 covers the first opening and is fixedly attached to the first wall 5. A plurality of first through-holes 11 are provided in the first baffle 9. Sound waves within the operating space 12 are thus transmitted through the first through-holes 11 into the first accommodating space 10 and attenuated by the first sound-absorbing component 8, thereby achieving noise reduction. The first sound-absorbing component 8 can be, but is not limited to, sound-absorbing cotton and can also be any other component that achieves the objectives of the invention.

[0029] Further, if Figure 2 As shown, the first sound absorbing member 8 further includes a first metal mesh 13. The first metal mesh 13 is fixedly disposed within the first storage space 10 and extends vertically. The first sound absorbing member 8 is connected to the first metal mesh 13. This ensures that the first sound absorbing member 8 is firmly fixed within the first storage space 10 and prevents it from settling downward due to gravity.

[0030] In actual production, the cross-sectional shape of the inner surface of the first receiving space 10 is sawtooth and / or wavy. In this way, the sound waves entering the first receiving space 10 can be reflected in different directions on the inner surface of the first receiving space 10, further improving the noise reduction effect.

[0031] As an optional implementation, Figure 2As shown, the second wall 6 further includes a second sound-absorbing component 14 and a second baffle 15. A second accommodating space 16 is defined within the second wall 6. The second sound-absorbing component 14 is disposed within the second accommodating space 16. The second accommodating space 16 forms a second opening (not shown) on the surface of the second wall 6 facing the first wall 5. The second baffle 15 covers the second opening and is fixedly connected to the second wall 6. A plurality of second through-holes 17 are provided on the second baffle 15. Sound waves within the operating space 12 can be transmitted through the second through-holes 17 into the second accommodating space 16, where they are attenuated by the second sound-absorbing component 14, thereby achieving noise reduction. The second sound-absorbing component 14 can be, but is not limited to, sound-absorbing cotton and can also be any other component that achieves the objectives of the invention.

[0032] Further, if Figure 2 As shown, the second sound absorbing member 14 is further provided with a second metal mesh 18. The second metal mesh 18 is fixedly disposed within the second storage space 16 and extends vertically. The second sound absorbing member 14 is connected to the second metal mesh 18. This ensures that the second sound absorbing member 14 is firmly fixed within the second storage space 16 and prevents it from settling downward due to gravity.

[0033] In actual production, the cross-sectional shape of the inner surface of the second accommodating space 16 is sawtooth and / or wavy. In this way, the sound waves entering the second accommodating space 16 can be reflected in different directions on the inner surface of the second accommodating space 16, further improving the noise reduction effect.

[0034] As an optional implementation, Figure 2 As shown, the cover plate 7 also includes a third sound-absorbing component 19 and a third baffle 20. A third accommodating space 21 is defined within the cover plate 7. The third sound-absorbing component 19 is disposed within the third accommodating space 21. The third accommodating space 21 forms a third opening (not shown) on the floor of the cover plate 7. The third baffle 20 covers the third opening and is fixedly connected to the cover plate 7. A plurality of third through-holes 22 are provided in the third baffle 20. This allows sound waves within the operating space 12 to be transmitted through the third through-holes 22 into the third accommodating space 21, where they are attenuated by the third sound-absorbing component 19, thereby achieving noise reduction. The third sound-absorbing component 19 can be, but is not limited to, sound-absorbing cotton and can also be any other component that achieves the objectives of the invention.

[0035] In actual production, the cross-sectional shape of the inner surface of the third storage space 21 is sawtooth and / or wavy. In this way, the sound waves entering the third storage space 21 can be reflected in different directions on the inner surface of the third storage space 21, further improving the noise reduction effect.

[0036] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
