摘要： A gas vent for a landfill includes a sub-surface gas collection manifold for collecting sub-surface gas from beneath a geomembrane. Preferably, the collection manifold includes a plenum for receiving sub-surface gas. A conduit is connected to and extends upwardly from the plenum, with the conduit communicating with the interior volume of the plenum and having an upper discharge end. The conduit is adapted and provided for communicating sub-surface gas from within the interior volume of the plenum through the geomembrane. A low-pressure relief valve is operative for opening when positive pressure exists within the conduit. The low-pressure relief valve comprises a valve membrane normally resting upon a seat and which is lifted off the seat by low positive pressure.

摘要： A relief valve for extracting sub-surface gas from beneath a geomembrane includes a valve body for permitting gas to flow therethrough and includes an inlet, an outlet, a vertical run communicating with the inlet, and a lateral run communicating with the vertical run and the outlet. A ball valve comprising a ball seat is positioned within the vertical run. A lightweight valve ball positioned within the vertical run. The valve ball is movable therewithin between a lowered position against a ball seat and an elevated position distal therefrom. The valve ball is lightweight enough that minimal upward gas flows within the vertical run cause the valve ball to rise and become unseated from the ball seat such that stoppage of such vertical flows or reverse flows cause the valve ball to drop back to its ball seat and seal against reverse flows through the ball valve.

摘要： A fail-safe gas collection system for collecting waste gas from a waste pile having an impermeable membrane covering substantially all or part of the waste pile. The fail-safe gas collection system includes an anti-lift topping for biasing the membrane to remain in place in the presence of winds. A network of conduits is positioned beneath and extends beneath the membrane. A plurality of collection nodes are positioned at spaced-apart positions on the network of conduits. A negative pressure pump is provided for drawing gas through the collection nodes of the network of conduits. An adjustable control valve is positioned between the network of conduits and the negative pressure pump. At least one pressure relief valve is provided to prevent the membrane from ballooning in the event that the negative pressure pump stops operating for a time.

摘要： A method for covering a site with synthetic turf includes laying down a first elongate strip of synthetic turf, laying down a second elongate strip of synthetic turf, with the second elongate strip of synthetic turf is laid down substantially adjacent to the first elongate strip of synthetic turf in a manner such that a portion of the second elongate strip partially overlays a portion of the first elongate strip forming a lap joint. The method also includes the step of applying heat and/or pressure to weld the first elongate strip of synthetic turf to the second elongate strip of synthetic turf along the lap joint.

摘要： A gas collection grid for use at landfills having a gas-producing waste pile, including a lower geocomposite positioned over the gas-producing waste pile, a protective layer of soil is positioned over the lower geocomposite. An upper geocomposite is positioned over the protective layer of soil such that the protective layer of soil is positioned between the lower and upper geocomposites. An impermeable geomembrane is positioned over the upper geocomposite. A cruciform gas collector conduit grid is positioned within or atop the protective layer of soil and has a plurality of collection orifices formed adjacent the vertical openings formed in the protective layer of soil. The impermeable geomembrane is non-perforated adjacent the collection orifices and the cruciform gas collector conduit grid is adapted for delivering collected gas laterally from beneath the geomembrane rather than vertically through the geomembrane.

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.
