Abstract

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.

Dependent claims

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 first and second parallel rows thereof defining a length of the sound attenuation barrier;
installing headers at intervals along said first course, perpendicular to said concrete stretchers, said headers each being of equal length to position said stretchers in a vertical plane for each of first and second sound attenuation faces of said sound attenuation barrier;
repeating the steps of installing the course of concrete stretchers so that said first and second rows thereof are positioned and separated by said headers and placing the headers perpendicular to said first and second rows to form a vertical array until a height for each of said first and second sound attenuation faces of the vegetated sound attenuation barrier is achieved;
configuring a plurality of said headers each with a respective internal portion, a first stretcher engagement portion between a first end of said internal portion and a first indexing key, and a second stretcher engagement portion between a second end of said internal portion and a second indexing key, wherein said first and second indexing keys are positioned at respective ends of said header to engage and prevent outward movement of a respective one or more of said stretchers, wherein each of said first and second stretcher engagement portions have a first height that separates respective upper and lower weight-bearing stretcher engagement surfaces, wherein each of said first and second indexing keys has a height greater than said first height, and wherein each of said internal portions has a height less than said first height;
placing soil inside said sound attenuation barrier;
and,
planting appropriate plants in the exposed soil positioned between the courses of the concrete stretchers and between successive ones of the headers at each end of said sound attenuation barrier.

5 more elements

A vegetated noise barrier for placement on a horizontal surface and extending substantially vertically upwardly therefrom with both sides thereof exposed for growth of plants to aid in sound attenuation and provide a pleasing aesthetic surface comprising:

a plurality of stretchers extending end to end in two parallel rows;
a plurality of headers extending perpendicular to said stretchers and defining the distance between said two parallel rows of stretchers;
a second plurality of stretchers positioned vertically above said first plurality of stretchers;
a second plurality of headers positioned vertically above said first plurality of headers to define rectilinear structure;
and,
further pluralities of headers and stretchers positioned vertically above to define the vertically disposed rectilinear structure of the desired height including headers that each have a respective internal portion, a first stretcher engagement portion between a first end of said internal portion and a first indexing key, and a second stretcher engagement portion between a second end of said internal portion and a second indexing key, wherein said first and second indexing keys are positioned at respective ends of said header to engage and prevent outward movement of a respective one or more of said stretchers, wherein each of said first and second stretcher engagement portions have a first height that separates respective upper and lower weight-bearing stretcher engagement surfaces, wherein each of said first and second indexing keys has a height greater than said first height, and wherein each of said internal portions has a height less than said first height, all of said headers being of equal length;
soil to fill the void formed by said pluralities of stretchers and headers with exposed portions there of extending between said pluralities of stretchers and headers;
wherein a sound attenuating structure having soil accessible through vertical sides and ends thereof is formed and wherein said height of each of said internal portions being less than said first height results in a vertically expanded plantable gap between successive ones of said headers at each end of said sound attenuation barrier.
