  • Patent number: 10253907
    Abstract: A fluorine gas functionalized surface of a fixture is chemically bonded to a fiberglass sump using a resin. The resin chemically reacts with the functionalized surface creating a strong, chemical bond between the fixture, which penetrates the shell of the sump, and the fiberglass shell of the sump. For example, the surface of the fixture is functionalized by a fluorine-containing gas mixture in an autoclave at a temperature, pressure and duration that creates C?O double bonds at the surface of a polyethylene fixture. The resin chemically reacts with the C?O double bonds and bonds with a fiberglass transition fitting capable of being joined to the shell of the sump.

  • Patent number: 9101968
    Abstract: A landfill soil cover system is proposed for preventing water infiltration into a landfill and gas emission from the landfill under all weather conditions. The landfill cover system comprises three soil layers; namely, a clay layer, a gravelly sand layer and a silt layer, compacted successively from the bottom to the top of the system. The clay layer is compacted immediately above an optional gas collection layer and landfill waste at an optimum water content. Additionally, a trench for water drainage may be constructed, for example, every 20-40 m in the horizontal direction. Water infiltration and landfill gas emission can be prevented effectively by this landfill soil cover system under any humid, semi-arid and arid climates.

  • Publication number: 20140154013
    Abstract: A wet well design that utilizes recycled material in sectional components to construct wet wells on site is disclosed. Traditional wet well components are made of pre-cast concrete. Green Recycled Material Component Wet Well components are constructed using recycled plastic, recycled steel and recycled Styrofoam. The method described herein for constructing the components and assembling the wet well on site addresses several logistical problems associated with the pre-cast concrete design including reducing project start to completion time, delivery costs, large crane rental costs and power line relocation costs. This design also enables construction of oblong wet wells in medians and other restricted areas as components can be straight or curved sections. Finally, this design eliminates the shifting of traditional cement well components due to uplift from underground water pressure through the use of a new anchoring system. Shifting can result in groundwater intrusion into the well.

  • Patent number: 7014391
    Abstract: A temporary berm or bin system, easily transported, erected without tools, and easily dismantled. A set of panels or planks is joined with sliding clips to form a bin having vertical or near vertical sides. The bin is lined with an impervious sheet of geocloth to form a containment berm for use in controlling the dispersal of hazardous material spilled from storage or work facilities. Spring loaded clamps hold the geocloth securely to the uppermost plank without nailing, sewing, or other labor consuming and/or tear prone methods. The berm is particularly suited to protect oil well drilling sites in environmentally sensitive environments such as arctic tundra. No excavation or other disturbance of the soil is required to erect the protective berm. The berm is secured to the ground by spiking through triangular support gussets. In the arctic, securing may be accomplished by freezing ice or mud as an “ice mortar” over the gusset feet and along the lower edge of the planking.

  • Patent number: 6896446
    Abstract: An advanced containment system for containing buried waste and associated leachate. A trench is dug on either side of the zone of interest containing the buried waste so as to accommodate a micro tunnel boring machine. A series of small diameter tunnels are serially excavated underneath the buried waste. The tunnels are excavated by the micro tunnel boring machine at a consistent depth and are substantially parallel to each other. As tunneling progresses, steel casing sections are connected end to end in the excavated portion of the tunnel so that a steel tube is formed. Each casing section has complementary interlocking structure running its length that interlocks with complementary interlocking structure on the adjacent casing section. Thus, once the first tube is emplaced, placement of subsequent tubes is facilitated by the complementary interlocking structure on the adjacent, previously placed, casing sections.
