[0020] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] Please refer to Figure 1-6 A soundproof wall for municipal engineering includes four corner columns 1, each column 1 having a cavity 11, each cavity 1 having two extension plates 13, the two extension plates 13 being vertically arranged within the cavity 11, and a support rod 2 being provided between two adjacent columns 1, the support rod 2 having a detachable soundproof plate 3.

[0022] The soundproof wall is rectangular in shape, with four pillars 1 at the four corners. A support rod 2 is provided between each pair of adjacent pillars, and the soundproof panel 3 can be installed and removed from the support rod 2. The whole structure can be used as an outdoor construction soundproof enclosure. When used outdoors, it can be used to enclose the construction site, such as to enclose drainage wells or road maintenance barriers. Indoors, it can also be used as a soundproof wall by fitting it against the wall. The overall structure is stable and has a good sound insulation effect.

[0023] Specifically, the top and bottom walls of the cavity 11 are provided with bases 12, the two ends of the extension plate 13 are fixed on the bases 12, the upper and lower sides of the extension plate 13 are provided with steps 14, and the surface of the steps 14 is provided with countersunk holes 15.

[0024] Each extension plate 13 corresponds to two upper and lower support rods 2. The support rods 2 cooperate with the extension plate 13 at the step 14. The support rods 2 are fixedly connected to the extension plate 13 at the countersunk hole 15 by bolts 5. The sound insulation plate 3 is located between the two support rods 2.

[0025] That is, the two support rods 2 are connected to the extension plate 13 at the step 14 by bolts 5. At this time, the two support rods 2 are parallel to each other, and the sound insulation plate 3 is installed between the two support rods 2; the length of the support rod 2 can be determined according to the distance between two adjacent columns 1.

[0026] In this embodiment, the sound insulation panel 3 is connected to the support rod 2 by a pin 4, and the pin 4 extends into the sound insulation panel 3 through the support rod 2.

[0027] In this embodiment, the sound insulation board 3 includes a perforated aluminum plate 31, a glass fiber sound insulation cotton 32, and a glass fiber sound absorption cotton 33. The perforated aluminum plate 31 is disposed on the inner side of the wall, and the glass fiber sound insulation cotton 32 is disposed between the perforated aluminum plate 31 and the glass fiber sound absorption cotton 33.

[0028] The surface of the perforated aluminum plate 31 is uniformly provided with multiple through holes, which can refract noise. In addition, the glass fiber sound insulation cotton 32 and glass fiber sound absorption cotton 33 can isolate and absorb noise, thereby increasing the sound insulation effect. Furthermore, there are gaps between the perforated aluminum plate 31 and the glass fiber sound insulation cotton 32, and between the glass fiber sound insulation cotton 32 and the glass fiber sound absorption cotton 33. That is to say, the three are not in contact with each other. The gaps can achieve sandwich sound insulation treatment, further improving the sound insulation effect.

[0029] In this embodiment, the perforated aluminum plate 31 has a perforation rate of more than 20% and a thickness of 2mm, the glass fiber sound insulation cotton 32 has a density of 60kg / m³, and the glass fiber sound absorption cotton 33 has a density of 48kg / m³.

[0030] Based on the above embodiments, when the soundproof wall is used indoors, sound-insulating sponge can be inserted into the gap between the upper and lower parts of the support rod 2 to increase the noise insulation area.

[0031] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
