Energy-saving and noise-reducing wall structure of green building

The invention relates to the technical field of green buildings, in particular to a green building energy-saving noise reduction wall structure which comprises an original wall and an outer wall, the original wall is arranged on a construction site, the outer wall is arranged on one side of the original wall, the green building energy-saving noise reduction wall structure further comprises a vibration starting mechanism and a noise reduction mechanism, and the vibration starting mechanism is installed in the outer wall; the noise reduction mechanism is installed above the vibration starting mechanism, a vibration transmission rack in the vibration starting mechanism moves upwards to drive a half-tooth gear of an auxiliary gear on the meshed side to rotate, a linkage gear of a linkage rotating block rotates through matched rotation of a ratchet wheel and a pawl, and contraction blocks distributed in a linear array are distributed at equal intervals from sparse to dense. The sound-absorbing blocks are arranged
