[0033] Example 2

[0034] Based on the structure of Example 1, Figure 3-4 As shown, the main body 41 includes an upper main body and a lower main body that are assembled. The upper main body includes a filter plate 411 and an upper cylinder 412 that are sequentially arranged from top to bottom.

The water on the top of the main wall can be drained to the bottom of the wall through the setting of the filtering holes 71; in addition, in order to facilitate drainage, a drainage pipe groove (not shown in the figure) can also be arranged at the bottom of the keel frame 3.

[0039] The working principle of the lightweight spliced ​​composite sound insulation wall described in the utility model is:

[0040] The noise first passes through the sound-absorbing board 2 and the sound-proof cotton 1, and the micropores in the sound-absorbing material can convert the noise into heat energy, thereby reducing the noise. Then, the noise passes through the main wall and multiple cavities inside the main wall, and the noise is reduced through space and distance. In addition, it can also play a role in heat preservation. Finally, it passes through the second layer of sound-absorbing board 2 and the second layer of sound-proof cotton 1 to further reduce the noise. In addition, the internal material of the wall unit 4 is mainly PP material, which is light in weight and easy to assemble. It can be prefabricated in advance, saving construction costs and construction time. At the same time, PP material can be recycled and is green and environmentally friendly; the wall unit 4 itself is simple and convenient to assemble, and the splicing combination method makes maintenance convenient and easy to replace damaged parts. At the same time, the wall unit 4 has a void structure composed of cavities, and a water filter hole 71 connected to the cavity is provided, which can drain water, prevent wind, reduce wind resistance, and further reduce noise.

[0041] During assembly, first fix the keel frame 3 to the ground to increase stability, and then install the wall unit 4; evenly fill the high-density sound insulation cotton 1 on the main wall surface and gaps to achieve better sound insulation effect; then install the sound-absorbing panel 2 on the main wall surface and fix it on the keel frame 3 to ensure that there is no gap between the sound-absorbing panel 2 and the sound insulation cotton 1; finally, grind the entire wall surface and apply waterproof and moisture-proof paint to complete the production of the sound insulation wall, which is easy to implement and low in cost.
