Abstract: A system for covering (i.e., closing) various types of sites where waste is deposited comprises a composite of one or more geotextiles that are tufted with synthetic yarns and an impermeable geomembrane, which is comprised of a polymeric material. The geotextiles can comprise polypropylene or polyethylene. The cover can include wind-resistant textured synthetic blade-like elements, such as vertical filaments, secured over a low-permeable polymer liner backing. Advantageously, the system does not rely on piled-on weight to resist wind forces and the cover can be deployed over a large area with little or no ballasting or anchoring. Optionally, the cover includes vertical filaments attached to the liner to break the wind aero-dynamics on the exposed cover. With this system, it is believed that the wind velocity on the impermeable surface (membrane) now becomes turbulent near the surface of the cover, thus greatly reducing the actual wind velocity at the liner surface and decreasing associated uplift.

Abstract translation: 用于覆盖（即关闭）废弃物的各种类型的场所的系统包括由合成纱线簇绒的一种或多种土工织物和由聚合材料构成的不渗透土工膜的复合材料。 土工织物可以包括聚丙烯或聚乙烯。 盖可以包括固定在低渗透性聚合物衬里背衬上的防风纹理合成叶片状元件，例如垂直细丝。 有利地，该系统不依赖于堆积的重量来抵抗风力，并且盖可以在很小或没有压载或锚定的大面积上展开。 可选地，盖子包括附接到衬套的垂直细丝，以将暴露的盖子上的风力动力学打破。 使用该系统，认为不透水表面（膜）上的风速现在在盖的表面附近变得湍流，从而大大降低了衬套表面处的实际风速并减少了相关联的隆起。

Abstract: A synthetic turf cover system for covering various types of ground where water and wind erosion protection are needed includes a non-woven synthetic textile drainage layer and a woven textile layer positioned beneath and adjacent the non-woven synthetic textile drainage layer. A plurality of synthetic grass blades extend above the non-woven synthetic textile drainage layer and through the non-woven synthetic textile drainage layer and the woven textile layer, and the synthetic grass blades are tufted into the woven textile layer. The non-woven synthetic textile drainage layer can comprise a needle punched synthetic non-woven fabric or an air-laid synthetic non-woven fabric.

Abstract: 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.

Abstract: 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.

Abstract: 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.
