Description

TECHNICAL FIELD

[0001] The utility model relates to railway facilities field, especially the sound barrier structure for railway existing line. BACKGROUND

[0002] The sound barrier is a kind of acoustic barrier specially designed between noise source and sound point, mainly used for sound insulation and noise reduction of railway, highway, highway, elevated composite road and other noise sources, and is widely applied.

[0003] For railway existing line, that is, the railway in the operating state, since the railway bridge does not reserve the sound barrier foundation or does not have the condition of erecting the sound barrier on the bridge body, only the independent pier outside the bridge can be newly added to increase the sound barrier foundation, to be used for sound barrier reinforcement. However, this method not only has high investment, but also has great construction difficulty, and needs to be improved. UTILITY MODEL CONTENT

[0004] In view of the deficiencies in the prior art, the utility model aims at providing a sound barrier structure for railway existing line, which can be applied to sound barrier reinforcement of existing line, has low investment cost and simple and fast construction.

[0005] The above technical purpose of the utility model is realized by the following technical scheme: a sound barrier structure for railway existing line, comprising a support frame arranged horizontally, a sound barrier plate is arranged on the side of the support frame facing the bridge body, two ends of the support frame are respectively fixedly connected with mounting frames, and the mounting frames can be connected with the pier through a plurality of fastening bolts.

[0006] In a preferred example, the utility model can be further configured as: the support frame is arranged as a truss structure, and the inner side of the support frame forms an inspection passage, and a support plate is fixedly connected to the inner side of the support frame horizontally to enable maintenance personnel to walk.

[0007] In a preferred example, the utility model can be further configured as: the mounting frame is arranged as a truss structure, and the mounting frame can be used as a pier inspection ladder, so that the maintenance personnel can climb into the inspection passage through the mounting frame.

[0008] In a preferred example, the utility model can be further configured as: the mounting frame is arranged in an inclined manner, and the distance between the bottom of the mounting frame and the bridge body is less than the distance between the top of the mounting frame and the bridge body.

[0009] In a preferred example, the utility model can be further configured as: the height of the mounting frame is 3m.

[0010] In a preferred example, the utility model can be further configured as: the height of the support frame is 3.5m.

[0011] In a preferred embodiment, the present invention can be further configured such that the distance between the upper surface of the support plate and the inner wall of the top side of the maintenance channel is 2.5m, and the width of the maintenance channel is 0.8m.

[0012] In a preferred embodiment, the present invention can be further configured such that the support frame and the mounting frame are respectively provided with a rust-proof layer.

[0013] In summary, this utility model has the following beneficial effects:

[0014] This sound barrier structure can be directly installed on railway bridge piers, making it suitable for reinforcing existing railway lines. Compared to adding independent piers on the outside of the bridge, this structure is less expensive, effectively reducing investment costs and improving construction efficiency. Furthermore, its layout avoids spatial interference with the overhead contact line supports of electrified railways, and the mounting frame can be used as an inspection ladder for the piers, offering greater versatility. Moreover, compared to cast-in-place concrete structures, this sound barrier structure can be prefabricated and assembled on-site, making construction simpler and more convenient.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Reference Figure 1 , Figure 2 A sound barrier structure for use on existing railway lines includes a horizontally arranged support frame 1. A sound barrier plate 2 is provided on the side of the support frame 1 facing the bridge beam. At the same time, mounting frames 3 are fixedly connected to both ends of the support frame 1. The mounting frames 3 can be connected to the railway bridge piers through multiple sets of fastening bolts. In other words, the sound barrier structure can be directly fixed to the railway bridge piers so that the sound barrier structure can be used for sound barrier reinforcement of existing railway lines.

[0021] Reference Figure 1 , Figure 3The support frame 1 is set as a truss structure, and the inner side of the support frame 1 forms an inspection passage 4. At the same time, the support plate 5 is horizontally fixedly connected to the inner side of the support frame 1 for maintenance personnel to walk on. That is, maintenance personnel can inspect the bridge through the sound barrier plate 2 in the inspection passage 4, making the maintenance work safer and protecting the personal safety of maintenance personnel.

[0022] Reference Figure 1 , Figure 3 The mounting frame 3 is set at an angle, and the distance between the bottom of the mounting frame 3 and the bridge beam is smaller than the distance between its top and the bridge beam, so as to avoid the bridge beam. At the same time, the mounting frame 3 is set as a truss structure, and the mounting frame 3 can also be used as a pier inspection ladder, so that maintenance personnel can climb through the mounting frame 3 to the maintenance passage 4, which not only increases the function of the mounting frame 3, but also realizes the rational use of resources.

[0023] Reference Figure 3 The mounting frame 3 is 3m high, the support frame 1 is 3.5m high, the distance between the support plate 5 and the top inner wall of the maintenance passage 4 is 2.5m, and the width of the maintenance passage 4 is 0.8m, so that maintenance personnel can pass through smoothly when carrying maintenance tools.
