SOUND ATTENUATING STRUCTURE

摘要

A free standing vegetated sound attenuating structure is formed by placing multiple layers of rows of concrete stretchers on a level surface with concrete headers extending transversely thereto to form a rectilinear structure with substantially vertical sides, in which soil can be placed within the void formed by the headers and stretchers. The vegetated sound attenuating structure is positioned in a vertical array upwardly from the level surface so that both sides of the vegetated sound attenuating structure are visible. Exposed areas of soil visible between successive layers of concrete stretchers have suitable sound attenuating vegetation growing therefrom. Irrigation means, which may be powered by solar panels, provides moisture for the growing of the sound attenuating vegetation. Seed containing tiles, panels or fabric may be used in contact with the soil to promote growth of vegetation.

主权项

1. A method of providing a vegetated sound attenuation barrier for areas adjacent highways, industrial facilities and the like, comprising the steps of:
leveling a ground area; laying a first course of concrete stretchers comprising two parallel rows thereof defining the length of the desired sound attenuation barrier; installing headers at intervals along said first course, perpendicular to said concrete stretchers, said headers having weight-bearing surfaces for engaging said stretchers and stretcher engaging keys or tabs positioned at the ends of said headers to prevent outward movement of said stretchers; repeating the steps of installing the course of concrete stretchers and placing the headers perpendicular thereto to form a vertical array until the height desired for the vegetated sound attenuation barrier is achieved; placing soil inside said vegetated sound attenuation barrier; and, planting appropriate plants in the exposed soil positioned between courses of concrete stretchers.
