摘要
The noise protection wall is constructed from stacked pre-fabricated parts, e.g. concrete panels (2), which have ends born on bearings (3) between the flanges (6) of a double-T beam. The bearings have upward and downward directed side parts, serving as distance pieces between panels and flanges. They also have similar parts projecting towards center strut or narrow side of a neighboring panel. The panels have tongues and grooves on alternating sides, but not in the areas supported on the bearings.
