Soundproofing green wall structure. The structure is made up of trestles (2) positioned transversely at regular or irregular intervals (E) and connected to one another by lateral meshed surfaces (8) designed to hold a planting substrate between them. The trestles (2) are also joined together at their bottom by longitudinal ballasting elements (11), notably made of concrete, embedded in the lower part of the planting substrate. The ends of the longitudinal ballasting elements (11) rest on transverse elements (7) made of concrete, provided at the base of the trestles (2).
