[0002] Noise not only affects people's daily life and work, but also may pose a potential threat to residents' health. Therefore, in order to reduce the impact of viaduct noise on the surrounding environment and residents, sound insulation devices need to be installed.

[0003] At present, the announcement number CN209760005U discloses a sound barrier for an urban traffic viaduct, which is provided with a supporting base; a vertical sound insulation board is installed on the upper end of the supporting base by cement pouring, and a number of noise absorbing holes are opened on the front of the sound insulation board, and a curved noise reflection board is installed on the upper part of the sound insulation board by bolts, and the surface of the curved noise reflection board is provided with wavy patterns; a noise absorption chamber is fixed by bolts behind the sound insulation board and the curved noise reflection board, and noise absorbing cotton is pasted inside the noise absorption chamber. The above technology can change the direction of noise propagation through the curved noise reflection board, prevent noise from spreading to the outside of the sound barrier, effectively attenuate noise, and reduce the size of the viaduct echo. The noise absorption chamber allows the transmitted noise sound waves to be absorbed by the noise absorbing cotton after multiple reflections, reducing the occurrence of noise sound wave diffraction, thereby greatly reducing the impact of noise on surrounding residents and blocking the spread of noise.

[0004] However, the above technology still has the following problems:

[0005] The existing viaduct sound insulation devices often require a lot of manpower and material resources during the installation process, and the stability after installation is poor, which affects the sound insulation effect. It is also inconvenient to transport the viaduct sound insulation devices. The installation process is too complicated, and it is not easy to replace some sound insulation panels when they are damaged. Summary of the invention

[0023] The utility model is a conveniently installed viaduct sound insulation device similar to the existing urban traffic viaduct sound barrier structure, such as the announcement number CN209760005U discloses an urban traffic viaduct sound barrier. The main improvement of the utility model is that the complete viaduct inverted L-shaped sound insulation mechanism 1 is divided into several parts for assembly, which is convenient for the staff to transport and install it. Figures 1 to 6 As shown, the utility model is an easy-to-install viaduct sound insulation device. During installation, the staff first fixes the support frame 2 on both sides of the viaduct road surface by bolts, and then places the first sound insulation board 4, the second sound insulation board 5 and the third sound insulation board 6 in the slide groove 3 in turn. The groove 9 on the bottom surface of the second sound insulation board 5 is sleeved on the upper end of the first sound insulation board 4, and the groove 9 on the bottom surface of the third sound insulation board 6 is sleeved on the second sound insulation board 5. Then, the arc sound insulation board 7 is placed on the upper end of the third sound insulation board 6. Similarly, the groove 9 on the bottom surface of the arc sound insulation board 7 is sleeved on the upper end of the third sound insulation board 6, and the arc sound insulation board 7 is fixed to the fixing block 8 with bolts, and the inverted L-type sound insulation mechanism 1 can be assembled.

[0024] like Figure 2 , Figure 3 or Figure 5 As shown, a fixing block 8 is fixedly connected to the upper end of the support frame 2, and a circular hole is opened on the surface of the fixing block 8.

[0025] Specifically, the arc-shaped sound insulation board 7 is fixedly connected to the fixing block 8 by bolts, and the arc-shaped sound insulation board 7 is connected to the third sound insulation board 6 to be in a stable state, forming a complete sound insulation barrier, thereby ensuring that it can block noise from all directions.

[0028] like Figure 2 or Figure 5 As shown, the sum of the heights of the first sound insulation board 4 , the second sound insulation board 5 and the third sound insulation board 6 is lower than the height of the support frame 2 .

[0029] Specifically, due to the influence of the width of the support frame 2, the width of the uppermost arc-shaped sound insulation board 7 is larger than the width of the third sound insulation board 6 below. The height difference facilitates the positioning of the arc-shaped sound insulation board 7 so that the threaded hole 10 on the arc-shaped sound insulation board 7 can be in the same position as the circular hole on the fixing block 8, thereby facilitating the fixing of the arc-shaped sound insulation board 7 on the fixing block 8.

[0030] like Figure 3 or Figure 6 As shown, threaded holes 10 corresponding to the circular holes are provided on the surface of the arc-shaped sound insulation board 7, and the arc-shaped sound insulation board 7 is fixedly connected to the support frame 2 by bolts.

[0031] Specifically, the threaded hole 10 corresponds to the circular hole on the fixing block 8, and the arcuate sound insulation board 7 is connected to the fixing block 8 by bolts, so that the arcuate sound insulation board 7, the third sound insulation board 6, the second sound insulation board 5 and the first sound insulation board 4 together form a complete sound insulation barrier.

[0032] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
