Elevated highway noise reduction and sound absorbing panels can also protect the environment and reduce noise pollution, which is of great benefit to residents along the route and road users.

[0003] When vehicles are traveling on urban elevated roads, they will generate airflow. The continuous airflow will constantly impact the noise reduction and sound-absorbing panels, which can easily cause the surface of the noise reduction and sound-absorbing panels to wear and deform, thereby reducing the service life of the noise reduction and sound-absorbing panels. When vehicles are traveling on elevated roads, the dust diffusion range on the road is increased, making the dust easier to spread, thereby reducing the surrounding environmental quality.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1 - Figure 4 As shown, in this embodiment, an elevated highway noise reduction and sound absorbing board includes a fixed base 3, a fixed rod 1 is respectively provided on the left and right sides of the fixed base 3, and the inner side of the fixed base 3 is hollow, a plurality of mounting plates 2 are fixedly installed in the middle of the fixed rod 1, a plurality of noise reduction rods 9 are embedded and installed in the middle of the mounting plate 2, and the inner side of the noise reduction rod 9 is filled with carbon ceramic particles 901, a noise reduction plate 8 is fixedly connected to one side of the noise reduction rod 9, a plurality of connecting sleeves 7 are provided on one side of the noise reduction plate 8, and the connecting sleeves 7 are all fixedly connected to the noise reduction plate 8, a sound absorbing board 5 is provided on one side of the connecting sleeve 7, and the sound absorbing board 5 is fixedly connected to the connecting sleeve 7, the inner side of the fixed rod 1 is hollow, and the fixed rod 1 is through-connected with the fixed base 3, and fixing bolts 4 are embedded and installed on both sides of the fixed base 3;

[0023] Specifically, through this arrangement, during installation, the fixed base 3 is placed on both sides of the elevated highway, and the fixed base 3 is fixedly installed by the fixing bolts 4, and the noise reduction rod 9 is embedded between the mounting plates 2 to install the noise reduction rod 9 in the middle of the fixed rod 1 for use, and at the same time, it is convenient to replace the noise reduction rod 9. When in use, the noise on the road is absorbed through the sound-absorbing holes 6 and transmitted to the noise reduction board 8 for silencing treatment to reduce noise. When a vehicle passes by, airflow is generated. When the airflow hits the sound-absorbing board 5, the buffer rod in the connecting sleeve 7 is used to relieve and dissipate the thrust of the airflow, so as to improve the stability of the fixed rod 1 and the overall service life of the elevated highway noise reduction and sound-absorbing board.

[0024] like Figure 1 - Figure 4 As shown, in this embodiment, the mounting plate 2 is obliquely symmetrically arranged in the middle of the fixing rod 1, the mounting plates 2 are staggered and equidistantly arranged, and the inner side of the mounting plate 2 is arranged in an arc shape, the inner side of the sound-absorbing plate 5 is equidistantly provided with sound-absorbing holes 6, and the inner side of the connecting sleeve 7 is provided with a buffer rod, the inner side of the carbon-ceramic particles 901 is provided with herbaceous plant seeds, and the seeds are non-vine and woody plant seeds, the outer side of the noise reduction rod 9 is provided with holes, and openings are provided on both sides of the fixing rod 1, and the openings are arranged corresponding to the inner side of the mounting plate 2;

[0025] Specifically, through this arrangement, when the noise reduction rod 9 is inserted into the mounting plate 2 for use, the carbon ceramic particles 901 are moistened by sprinkling water to facilitate the germination and growth of grass seeds. Since herbaceous plants (such as grasses) are a type of plant with a fast growth period, tender plants, thin rhizomes, and no wood, through the growth of herbaceous plants, their rhizomes are intertwined and connected between the mounting plate 2 and the noise reduction rod 9 to strengthen the overall stability of the elevated highway noise reduction sound absorbing board. At the same time, the plants grow from the gap between the mounting plate 2 and the noise reduction rod 9 to the sound absorbing board 5. Growing out, the herbaceous plants growing toward the sound-absorbing board 5 form a plant wall of a certain density. When vehicles on the elevated highway pass by, the plant wall can improve the effect of sound absorption and noise reduction, and at the same time reduce the dust when the vehicles are driving, so as to carry out urban greening. In the daily growth of the plants, they are nourished by rainfall, and at the same time, the rainwater is collected from the openings through the mounting plate 2 to the inside of the fixed pole 1 and the fixed base 3, so as to provide moisture for the plants in weather with less rain, and the plants can also be watered when watering the highway for maintenance.

[0026] It should be noted that when using the utility model as an elevated highway noise reduction and sound absorbing board, first place the fixed base 3 on both sides of the elevated highway, and fix the fixed base 3 with the fixing bolts 4, and embed the noise reduction rod 9 between the mounting plates 2 to install the noise reduction rod 9 in the middle of the fixed rod 1 for use, so as to facilitate the replacement of the noise reduction rod 9. When in use, the noise on the road is absorbed through the sound absorbing holes 6 and transmitted to the noise reduction board 8 for noise reduction treatment to reduce noise. When a vehicle passes by, airflow is generated. When the airflow hits the sound absorbing board 5, the thrust of the airflow is relieved and dissipated through the connecting sleeve 7 to improve the stability of the fixed rod 1 and the service life of the elevated highway noise reduction and sound absorbing board. When the noise reduction rod 9 is inserted into the mounting plate 2 for use, the carbon pottery particles 901 are moistened by sprinkling water to facilitate the germination and growth of grass seeds. Since herbaceous plants (such as grasses) are a type of plants with a fast growth period, tender plants, thin rhizomes, and no wood lemma, through the growth of herbaceous plants, their rhizomes are intertwined and connected between the mounting plate 2 and the noise reduction rod 9 to strengthen the overall stability of the elevated highway noise reduction and sound-absorbing panel. At the same time, the plants grow from the gap between the mounting plate 2 and the noise reduction rod 9 toward the sound-absorbing panel 5. The herbaceous plants growing toward the sound-absorbing panel 5 form a plant wall of a certain density. When vehicles on the elevated highway pass by, the plant wall is used to improve the sound absorption and noise reduction effect, and at the same time, dust is reduced when vehicles are driving, so as to carry out urban greening. During the daily growth of the plants, they are nourished by rainfall. At the same time, the mounting plate 2 collects rainwater from the opening to the inside of the fixed rod 1 and the fixed base 3 to provide moisture for the plants in weather with less rain. At the same time, the plants can also be watered when watering the highway for maintenance.
