Benefits of technology

[0010]In light of the problems associated with conventional silt fences, it is a principal object of the invention to provide an erosion control

Problems solved by technology

Topsoil lost from an area may have taken centuries to develop and can be exceedingly costly to replace.
Eroded soil loses its ability to retain precipitation, resulting in faster runoff and flooding.
Roadways, bridges and other structures can wash out due to flooding and undercutting.
Eroded sediment can be damaging too.
It clogs storm water drainage systems.
Also, it pollutes rivers and streams, choking aquatic life and increasing water purification costs.
Finally, it can diminish the aesthetic quality of the environment.
Properly constructed silt fences are known to fail

Embodiment Construction

[0020]Referring now to FIG. 1, an erosion control barrier in accordance with the present invention is shown at 10. Barrier 10 includes an elongated boom 12 anchored by posts as at 14 driven into the ground 16. Extending upwardly from boom 12 is an aboveground wing 18 that traps runoff that may spill over boom 12. Extending downwardly from boom 12, however, is an underground wing 20 that prevents runoff from passing beneath boom 12.

[0021]The principal features of barrier 10 are made by folding and stitching a rectangular sheet of cloth 22. As shown, the top of cloth sheet 22 is folded upon itself and stitched along the length of the overlapping parts by a plurality of laterally spaced seams 24 so as to produce a hem 26 whose interior is accessed through pockets or openings 28 provided by gaps between seams 24. Sheet 22 is also folded a second time and stitched to produce a tube 30 spaced from, and parallel to, hem 26 and a pair of wings 18 and 20 extending outwardly from tube 30. Tub...

Abstract

An erosion control barrier including a boom having a tube, formed of geotextile, that is filled with an absorbent batting. An aboveground wing, formed of geotextile, is affixed to the tube and extends along the length of the tube. The top of the aboveground wing projects above the top of the boom and is provided with a pocket. A ground-penetrating post is positioned adjacent the boom. The top of the post is inserted into the pocket for supporting the top of the aboveground wing.

Description

FIELD OF THE INVENTION[0001]The present invention relates generally to hydraulic and earth engineering and, more particularly, to apparatus for bank, shore, or bed protection purposes.BACKGROUND OF THE INVENTION[0002]Soil erosion has occurred since landmasses formed upon the earth. Prior to the industrial revolution, forests and grasses covered most of the land and protected the soil under layers of leaf litter. Erosion proceeded at a relatively slow rate and was hardly noticed by man.[0003]Accompanying widespread settlement over the last few centuries came a need to dwell upon, and derive other benefits from, large swaths of land. People purposefully removed trees, shrubs, and grasses from selected areas first to establish farms and villages and, then, to construct cities, factories, roadways, utility right-of-ways, mines, and residential subdivisions. This removal of vegetation has permitted storm runoff to erode soil more quickly and noticeably.[0004]The erosion of soil scars the...
