The invention has the following beneficial effects: the sound absorption plate mounting structure adopts the eccentric block made of elastic materials to fix the sound absorption plate with a symmetrical inclined plane structure, assists the bonding mode of the back surface, and can stably and firmly fix the sound absorption plate with the support rib column; meanwhile, the structure that two eccentric blocks are arranged on the symmetrical inclined plane is adopted, and the eccentric blocks are opposite to the rotating direction of the inclined plane, so that when a possible sound absorbing plate moves, the sound absorbing plate can be balanced and stable always under the rotation of one of the two eccentric blocks, and the sound barrier has good self-adaptive stability in a complex environment. The mounting block is made of ethylene propylene diene monomer rubber with excellent performance, and is fastened on a reserved mounting hole of the sound barrier by using a stainless steel expansion bolt, and the mounting method is adopted. The invention has simple, stable and reliable mounting structure; the size adjusting range is large, and the phenomenon that the installation cannot be carried out due to size and position differences is avoided; the maintenance is convenient, and the replacement is easy.
