    摘要: A non-woven mat of randomly oriented thermoplastic or polymeric fibers defining interstitial gaps that form interference pathways for non-direct water flow therethrough, whereby the mat being disposed on a ground surface moderates a rate of flow of environmental water for increased seepage of the environmental water into a subground and resists rapid lateral flow of environmental water across the ground cover, and with a stabilization layer in a bottom surface portion of the mat or optionally secured with staples to the ground. A method of forming a stabilized water flow control ground cover is disclosed.

    摘要: A near-surface wellhead for extracting sub-surface gas from beneath a geomembrane includes a plenum defining an enclosure with an upper portion. A conduit extends upwardly from the upper portion of the plenum, the conduit communicating with the interior volume of the plenum and has external threads for receiving a threaded nut thereon. The conduit is adapted and provided for extending through an aperture in the geomembrane for withdrawing sub-surface gas from within the interior volume of the plenum and through the geomembrane. A gasket having an opening formed therein is slipped over the conduit and above the geomembrane so that the geomembrane is sandwiched between the gasket and the upper portion of the plenum. A threaded nut is fitted to the conduit and above the gasket for securing the gasket against the geomembrane, thereby sealing the geomembrane to the upper portion of the plenum.

    摘要: A tufted geotextile cover system, comprising a backing sheet tufted with first tuft lines of tufts on a first spacing and second transverse tuft lines of tufts on a second spacing greater than the first spacing to dispose the second tufts intermediate opposing pairs of the first tuft lines that define interstices for receiving infill, the tufts in the second tuft lines increasing resistance of the infill to displacement and dry flow movement in response to loading on the geotextile overlying a surface for covering a ground site. A closure system is disclosed using the tufted geotextile as a component overlying an impermeable geomembrane for resisting inflow of water below the ground surface.

    摘要: A geoturf tube for stabilization of erodible ground surfaces said geoturf tube formed of a geotextile fabric in a tubular shape and configured to contain sands but allow water to pass through and a tufted tensile elements cover attached to at least a portion of the geotextile fabric. Alternatively, a geoturf cover of a geotextile and a plurality of tufted tensile elements installed as a separate layer above a geotube to serve as a protective barrier and extend the service life of the geotube. A method of stabilization of erodible surfaces with a geoturf tube or a geoturf cover is disclosed.
