In this embodiment, the vibration insulator is made of a polyurethane elastomer. The polyurethane elastomer is a synthetic polymer material between rubber and plastic, has the characteristics of isotropy, large deformation and high elasticity, is a typical super-elastic material, and is widely applied to the fields of automobiles, aerospace, medical treatment, national defense and the like. The density of the vibration isolator made of polyurethane elastomer is generally 1.1-1.25 kg/m3。
In the application of the vibration isolator, the vibration isolator is arranged at the periphery of a dynamic compaction construction area and in a position where vibration isolation is needed. Usually, the vibration isolator is arranged around the periphery of a dynamic compaction construction area, and the cross section of the vibration isolator is in a closed belt shape. For example, vibration insulators having a rectangular band-shaped cross section are provided around a dynamic compaction construction area. The vibration isolator is arranged in the vibration isolation groove on the periphery of the dynamic compaction construction area.
