Expressway sound barrier
The invention provides an expressway sound barrier which comprises stand columns, cross beams (2), a collision avoidance structure (5), a rubber vibration isolating layer (4) and a sound absorbing and isolating plates. The collision avoidance structure (5) is located at the outer side of a road. The rubber vibration isolating layer (4) is arranged at the top of the collision avoidance structure (5). The multiple stand columns are located at the outer side of the collision avoidance structure (5). The adjacent stand columns are connected through the cross beams (2) located at the same height. Each stand column is in an inverted-L shape and comprises a stand column vertical part (11) and a stand column horizontal part (12) located at the top of the stand column, wherein the stand column vertical part (11) and the stand column horizontal part (12) are fixedly connected. The bottoms of the stand column vertical parts (11) are fixedly connected with a base, and stand column corner reinforcing ribs (13) are arranged at the lower ends of the stand column vertical parts (11). The noise reducing effect of the sound barrier is remarkable, a connecting device is designed reasonably, construction is convenient, connecting strength is high, and the sound barrier can be widely applied to the field of highways and railways.
