Abstract: Methods and systems are disclosed for manufacturing or reinforcing of any length, shape, size, and any thickness pipe with a plurality of layers comprising at least a first reinforcement sheet, a pre-designed and localized resin-fortified Core, and a second reinforcement sheet. The Core includes “A-regions” which are designed to absorb less resin, and “B-regions” which are designed to absorb more resin. For reinforcing a pipe, a first reinforcement sheet is placed over the inside and/or the outside surface of the pipe. A pre-designed and localized resin-fortified Core is placed over and adhered to the first reinforcement sheet. Subsequently a second reinforcement sheet is placed over the surface of the Core, such that the Core stays between the first and the second reinforcement sheet. Next, the resin-saturated sheets and Core are cured—depending on the type of resin—by partial or complete exposure to ambient temperature, to heat, or to light.

Abstract: A method and an article of manufacture are disclosed for constructing, reinforcing, and repairing various structural elements such as columns, piles and the like using formworks that are reusable. The reusable articles of manufacture employed in the disclosed methods are or, if desired, may be permanently left in place. Same or similar methods and articles of manufacture may be employed to easily construct pipes of any desired diameter in a very short time.

Abstract: Methods and systems are disclosed to transfer forces on a damaged pile to the lower part of the pile, bypassing the damaged area. Rings of various materials are tightly wrapped around the pile or clamps are attached to the pile, above and below the damaged area, causing calculated friction between the pile and the rings and/or clamps. Subsequently the damaged area and the rings and/or clamps are encased in a curable substance, such as concrete. After curing, the rings and/or clamps above the damaged area will receive the stresses on the pile through the friction with the pile and will transfer them to the concrete which in turn will transfer the stresses to the lower part of the pile through the lower rings and/or clamps and their friction with the lower part of the pile. Nothing is welded to the pile and the pile is not altered in any way.

Abstract: A method and an article of manufacture are disclosed for reinforcing various structures with only partially accessible circumference, such as columns closely adjacent to or protruding out of a wall or beams holding a ceiling. Some of these structures may be partly or completely submerged in water, such as retaining walls on the sides of rivers and water-ways. In some embodiments a prefabricated shell will fully or partly cover the exposed and reachable part of the structure and will be secured in place by various means. The shell may hug the structure tightly or loosely and the space between the shell and the structure may be filled with such curable materials as glue, epoxy, grout, concrete and the like. In various embodiments additional reinforcement such as rebar may be placed in the space between the shell and the structure.

Abstract: Mining methods and systems are disclosed for In-Situ Leaching (ISL) of the mineral ores. ISL extraction is conducted by injecting a suitable leach solution into the ore zone below the water table; oxidizing, complexing and mobilizing the minerals; recovering the pregnant (loaded) solutions through production wells (extraction wells or recovery wells); and, finally, pumping the minerals bearing solution to the surface for further processing. In these methods strips of fabrics saturated with resin are helically or non-helically wrapped around desired shape vertical mandrels, located over the wells, and the partially cured pipes are lowered into the wells to line the wells. These onsite manufactured pipes/linings are used to pump chemical solutions into the ores and subsequently to recover the pregnant (loaded) solutions.

Abstract: Methods and apparatus for transporting cool water from the deep regions of the oceans to the shallow waters of the shoreline by a network of, for example, onsite manufactured FRP (Fiber Reinforced Polymer) pipes and pumps. This water displacement lowers the temperature of the shallow water region to a desired level. To implement this method, a long pipe is laid over the seabed, extending from the shallow regions to a desired depth of the ocean where the water is cooler and cleaner than the shallow waters. A mechanical and/or an electrical water pump is then attached to either end of the pipe. The water pump, preferably energized by the water surface waves, will constantly pump the cooler and cleaner water from the depth of the ocean to the shallow waters, reducing the temperature and contamination of shallow waters.

Abstract: Methods are disclosed for on-site construction of continuous concrete pipes. In some embodiments a tunnel is bored in the ground instead of traditional excavation of a ditch for the pipe. At least one layer of concrete or other similar materials is sprayed/applied on the wall of the tunnel. Optionally a mesh of reinforcement material is laid over the concrete layer(s). Subsequently additional layer(s) of concrete is sprayed on the previous layers. The spraying process in these methods may be manual or mechanized. In other embodiments the soil removed from the tunnel may be used to mix the concrete. Utilizing the disclosed methods, new continuous pipes may be formed within old pipes or damaged pipes.

Abstract: The present invention is a method for strengthening a vertical column, such as piles under piers and docks and for columns in bridges and buildings. A coiled FRP laminate is provided and wrapped in a helical fashion around the column, with the laminate overlapping itself. An epoxy resin coating is applied between the overlapping portions. The epoxy resin will then cure to form a substantially water tight shell. A plurality of spacers may be fixed to the column and adapted to hold the laminate a set distance away from the column. A plurality of sealing means is provided to seal the space between the shell and the column. A filler material may be pressurized to fill the space, penetrate cracks in the column, and displace water. Also, a plurality of rigid strengthening rods may be added between the column and the shell to further strengthen the column.

Abstract: Method and article of manufacture are disclosed for on-site manufacturing of any length, any shape, size, and any thickness pipe. Sheets of materials fulfilling the requirements of the inner surface of the pipe is first wrapped around a mandrel of a desired size and cross-section to form a pipe-liner. As described, the pipe-liner can also be manufactured by spraying fast-setting materials on the mandrel or injecting desired materials into a form surrounding the mandrel. Afterwards, fabrics saturated with resin are wrapped around the manufactured pipe-liner. Completed pipe section is partially pushed off the mandrel and another similar partial pipe is manufactured around the mandrel as a continuation of the previous partial pipe section. This process is repeated to manufacture a seamless pipe of any desired length. Disclosed pipes eliminate almost all weaknesses of plastic, metal, and concrete pipes and noticeably reduce costs of transportation and manufacturing.
