In addition, when the sound insulation board is installed, a gap can appear between the common sound insulation board and the sound insulation board, in order to solve the problem of the gap, the gap is usually filled by using a gap filling device when the sound insulation board is installed, and the gap filling device is used for injecting a sol rod from a gun head after the sol rod is heated and melted, so that the gap is filled, and the whole filling construction process is complicated.

Aiming at the problems, the invention provides an energy-absorbing spongy composite metal and an application structure thereof.
