Technical Field

Background

Compared with underground lines and ground lines, the construction cost and the operation energy consumption of the urban rail transit overhead lines have great advantages, so that the overhead line laying mode is adopted by many urban traffics in China, such as overhead roads, overhead rails, overhead bridges and the like. Because no obstacles such as trees and the like exist around the track bridge erected at the high position, noise generated by the train running on the overhead line is easier to spread, and noise pollution is caused.

At present, in order to solve the problem of noise pollution, the problem of noise pollution is solved to a certain extent though the problem of noise pollution is solved by installing the sound barrier plates on the two sides of the overhead line, but does not consider that no trees or other buildings block the periphery of the high-rise track, the crosswind airflow on two sides of the overhead line is larger, particularly, for coastal areas with frequent strong wind weather, the crosswind airflow at two sides of the overhead line impacts vehicles in a driving area, especially the airflow impact force is maximum when the direction of the crosswind airflow is vertical to the vehicle body surface, the driving safety and the comfort are reduced, because the sound barrier is a wind-proof plate-shaped structure, although the air flow at two sides of the elevated line is blocked to directly act on the vehicle, however, the airflow impacts the sound barrier plate, and simultaneously increases the wind load borne by the overhead line, so that the stability of the overhead line structure such as an overhead road, an overhead rail, an overhead bridge and the like is influenced.

As shown in fig. 1, the frame 2 is a field-shaped frame 2 composed of a horizontal frame 21 and a vertical frame 22.

The sound absorption layer 102 is formed by combining quadrilateral structures and mainly plays a role of absorbing noise, and a panel on one side close to the rail is provided with a plurality of irregular tiny holes which are arranged below each quadrilateral structure, so that the sound absorption layer can play a role of absorbing noise and can prevent rainwater from gathering in the structure.

The stabilization layer 101 makes full use of the stability characteristics of the triangle, the layer structure is formed by the triangle, the effect of stabilizing the internal structure of the sound insulation board 1 is mainly achieved, and the deformation of the sound insulation board 1 due to wind load in the installation and later-stage use processes is avoided.

The deformable layer 105 utilizes the easy deformable feature of the parallelogram, and the layer can deform under the action of wind load to change the flow direction of wind and reduce the load of the side wind on the sound barrier 100. The connection mode of each corner of the quadrangle in the layer structure is fixedly connected, so that the deformation of the deformation layer is avoided from being too large, and certain deformation capacity is ensured.

The frame 2 is a load-bearing structure of the baffle 1 and is a framework of the sound barrier 100. The acoustic panels 1 are mounted on a frame 2, which together form a complete acoustic barrier 100. In order to fully exhibit the characteristics of the deformation layer in the present invention and enable the present invention to exert a better noise protection effect, the frame 2 in the present invention is an optimized arc-shaped frame 2 (refer to fig. 11). The shape can effectively surround noise on a track line, has a good air guiding effect, avoids overlarge deformation of a deformation layer caused by side wind, and reduces the load of the side wind on the sound barrier 100.

The noise protection of the present invention is mainly based on the transmission and absorption in the life cycle, and mainly plays a role of the acoustic panel 1 of the present invention. The sound absorbing layer 102 of the baffle 1 mainly functions to absorb noise transmitted from the rail, and absorbs the noise by the small holes in the surface layer on the side facing the rail. When the first sound absorbing layer 102 of the sound insulation panel 1 cannot completely absorb noise, the stable layer 101 and the deformation layer 105 of the sound insulation panel 1 can effectively block the noise from propagating outside the protection range of the sound barrier 100 and absorb the noise in the internal structure thereof by using the structural material and the internal cavity thereof.

As shown in fig. 1, the soundproof panel 1 is mounted in a framework 2 of a shape like a Chinese character tian composed of vertical frames 22 and horizontal frames 21, and constitutes a sound barrier 100 together.

The invention is a modularized combination, can be manufactured in a factory firstly and then assembled on site, and the specific assembling degree and the installation procedure are comprehensively considered by combining the actual situation and the transportation condition on site.

The present invention has a certain deformation capability, and therefore requires that the material can endure repeated deformation, especially the deformation layer 105 of the sound barrier 100 unit, and the connection node between the materials needs to endure multiple deformation. The stable layer 101 of the sound barrier 100 of the present invention needs to ensure the structural stability of the whole sound barrier 100 unit, so the strength of the material should be high. In addition, the material of the invention also has the characteristics of light weight, durability, environmental protection and the like so as to ensure the safety and the economical efficiency of the invention.

The sound insulation board 1 comprises three layers of structures, namely a sound absorption layer 102, a stable layer 101 and a deformation layer 105, wherein the three layers of structures are all realized by an organic arrangement geometric structure, and other geometric forms or materials meeting the performance requirements of the layers of structures can achieve the same effect as the sound insulation board.

The invention can be expanded to a double-sided sound absorption and insulation barrier, and the sound absorption layers 102 are arranged on both sides of the sound insulation board 1 in the invention, so that both sides of the sound insulation board 100 can simultaneously absorb noise, thereby reducing the outward transmission of the noise.

The sound absorption and insulation of the invention are realized by the characteristics of the structure, and in order to improve the sound absorption and insulation effect, a filling material with light weight and good sound absorption and insulation effect can be added into the structure layer.

All the components of the invention can be made of the same material.

The invention is formed by organically arranging and combining regular geometric shapes, and is a highly compact composition structure.

The sound absorption and sound insulation of the invention are realized by the structural characteristics of the whole structure, and do not depend on other materials.

In addition, the invention also provides a track system, which comprises a sound barrier and a track, wherein the sound barrier is arranged on two sides or one side of the track, and the sound absorption layer 102 of the sound barrier is arranged facing the track, wherein the sound barrier can be the sound barrier in the previous embodiment.
