The sound-absorbing layer 2 and the sound-insulating layer 4 are arranged between the front wall 1 and the rear wall 6. The sound-absorbing layer 2 is arranged on the rear side of the front wall 1, and the sound-insulating layer 4 is arranged on the rear side of the sound-absorbing layer 2. The positioning frame 3 is arranged between the sound-absorbing layer 2 and the sound-insulating layer 4, and the rear wall 6 is arranged on the rear side of the sound-insulating layer 4. The bottom cotton 5 is arranged between the rear wall 6 and the sound-insulating layer 4. The front wall 1 is the internal structure of the wall. , providing basic support and protection; the sound-absorbing layer 2 absorbs the energy of sound, thereby reducing the reflection and transmission of sound; the positioning frame 3 ensures the distance between the sound-absorbing layer 2 and the sound insulation layer 4 to avoid direct contact between the two; the sound insulation layer 4 blocks the propagation of sound and reduces the penetration of sound by reflecting and isolating sound waves; the bottom cotton 5 is filled between the rear wall 6 and the sound insulation layer 4 to provide additional sound insulation effect and enhance the overall stability of the wall; the rear wall 6 is the external structure of the wall, and together with the front wall 1 constitutes the main body of the wall, providing support and protection.

[0020] Connecting steel bars 7 are arranged between the front wall 1 and the rear wall 6. The main function of the connecting steel bars 7 is to enhance the connection strength and integrity between the front wall 1 and the rear wall 6. As a structural reinforcement, the connecting steel bars 7 penetrate or connect the front and rear walls 6 to tightly connect the two together to form a stable overall structure.

[0021] An anti-cracking grid 11 is arranged at the front end of the front wall 1, and latex paint 12 is arranged on the front side of the anti-cracking grid 11.
