Traditional earth brick or concrete wall panels contribute significantly to the building's total weight, significantly impacting its seismic safety. These panels are heavy and offer poor seismic performance. They also suffer from poor sound insulation, thermal insulation, and heat preservation. Traditional concrete wall panels consume a lot of energy to manufacture, and once discarded, they become construction waste, making them difficult to dispose of and environmentally unfriendly.

[0003] Furthermore, the rapid development of the low-altitude economy has led to an increasing demand for terminal construction. Low-altitude aircraft continuously generate multiple vibration noises during takeoff and landing near terminals. Specifically, aircraft directly generate primary noise and vibration during takeoff and landing. Excessive vibration can also cause secondary radiated noise from the wall panels, further exacerbating the impact of the terminal's vibration noise. Currently, traditional adobe or concrete wall panels struggle to meet the high noise reduction requirements. The vibration noise issues facing terminals caused by low-altitude aircraft remain unresolved.

[0004] As can be seen from the above, developing a prefabricated, vibration-damping, noise-reducing, sound-insulating, and heat-insulating environmentally friendly wall panel is a pressing issue. Furthermore, a production process corresponding to these new prefabricated, vibration-damping, noise-reducing, sound-insulating, and heat-insulating environmentally friendly wall panels is also needed to facilitate the production of the wall panel structure and improve production quality and efficiency.

[0069] In one embodiment, the hollow cavity 11 of the bamboo wrapped cuboid 1 is further provided with a layer of polyurethane foam; the polyurethane foam is used to further improve the thermal insulation, heat insulation and sound insulation performance of the wall panel.

[0070] In one embodiment, the vertical modal natural frequency of the wall panel is set to ω n The input vibration frequency of the wall panel is set to ω; then the ratio of the input vibration frequency of the wall panel to the vertical modal natural frequency of the wall panel must satisfy: The frequency value of the vertical modal natural frequency of the wall panel can be obtained by adjusting the water level of the liquid water 3 in the hollow cavity 11 .

[0072] In one embodiment, the vertical vibration isolation performance of the novel wall panel 8 of the present invention can be qualitatively represented by a single degree of freedom vertical vibration isolation system controlled by the following equation of motion:

[0073]

[0074] Among them, m represents the mass of the wall panel, c and k represent the vertical damping ratio and vertical stiffness of the wall panel, u, and represent the vertical displacement, velocity and acceleration of the wall panel, respectively.

[0084] The acceleration transfer coefficient Tr can be solved as:

[0085]
