Patent ID: 6986624

Claim:
A porous tubular windblown particle control device for attachment to a surface of the earth to stabilize particle cover and to control deposition and retention of windblown particles, comprising: a sheet of netting material formed from a plurality of webs linked together to define apertures between the webs and through the sheet, the netting sheet having a longitudinal dimension and a transverse dimension; a plurality of frame structures, each frame structure including at least one anchor element to connect the frame structure to the earth surface, each frame structure defining a closed geometric configuration having an open center with horizontal and vertical dimensions across the open center and an outer peripheral shape circumscribing the open center; and netting connectors connecting the sheet of netting material to the plurality of frame structures with the plurality of frame structures positioned in a longitudinally spaced apart relationship along the longitudinal dimension of the sheet of netting material and with the outer peripheral shape of each frame structure extending in the transverse dimension of the sheet of netting material; and the sheet of netting material assuming a generally tubular cross-sectional shape generally corresponding to the outer peripheral shape of the plurality of frame structures when connected to the frame structures; the transverse dimension of the sheet of netting material is sufficient to extend the sheet of netting material over a substantial majority of the outer peripheral shape of the frame structures to a location adjacent the earth surface; and the sheet of netting material has sufficient inherent strength in the longitudinal dimension to maintain substantially the same generally tubular cross-sectional shape between the longitudinally spaced apart frame structures upon connecting the frame structures to the earth surface at the anchor elements.
