20100232878Universal Framed Cofferdam - Universal Framed Cofferdam has prefabricated skeletal steel space framing formed from multiple steel vertical pipes and two levels of horizontal diaphragm trusses rigidly connected to pipe columns. Beams of each diaphragm truss are attached to vertical pipes of the framing with rigid moment connections creating a rigid space frame of the perfectly round form that is used as a false work of the Cofferdam. Wales of the Cofferdam and short pieces of the flat sheet piling are attached to the vertical pipes forming a skeleton of the Cellular structure. The Skeleton of the Universal Framed Cofferdam is prefabricated in the convenience of the Dry Dock and than floated to the site. Buoyancy of the framing allows Cofferdam skeleton transportation without using the barge or otherwise necessary floating devices. Once brought to the site of installation Cofferdam skeleton is installed vertically in position and leveled on the bottom of the river bed. If necessary river silt can be jetted and pumped out of pipe annular space and pipe columns of framing can be simultaneously lowered in position by using vibro—hummer. After space framing installation, rock sockets are predrilled through the annular space of vertical pipes and rock anchors installed. Sheet pile skin of the Cofferdam installed between pipe columns concludes Cofferdam Can erection. Universal Framed Cofferdam Can than filled with compacted gravel and becomes a Hybrid Gravity Caisson/Columnar water front or marine structure that has the best features of the Conventional Cellular Cofferdam and of Columnar Dolphin structure. It has enhanced sliding and overturning stability provided by Rock anchors preloaded by Cofferdam granular fill and has effective mechanism that prevents concave or convex surface of rupture failure that may be suffered by conventional Cellular Cofferdams, and has mechanism that more effectively resists deep surface sliding failure of the Cofferdam base.09-16-2010
20100189503Coffer dam for servicing marine structures - A coffer dam for use in maintenance and repair of support pylons for marine structures such as piers, wharfs, and drilling platforms. Insulated bottom, side walls and roof members form an enclosure that can be heated, or cooled, to provide a good work environment and can protect against undesirable condensation that could adversely effect chemicals and coating materials. A grated floor member allows for debris to be collected and a vacuum system is used for proper disposal, and an improved seal protects against water leaking into the enclosure.07-29-2010
20110064520DEVICE FOR PREVENTING ICE FORMATION ON A SURFACE LAYER - The invention is concerned with an arrangement for preventing weather-induced formation of ice to a top surface (03-17-2011
20120224920COFFERDAM MODULES - A cofferdam module can include first and second side panels, outer support members that are each coupled to the outer side of one of the side panels, and two different types of inner support members that are each coupled to the inner side of each of the side panels.09-06-2012

20100119306Ground thawing mat and apparatus for making same - A ground thawing mat includes at least a flexible upper sheet overlaying a serpentine twinned array of flexible heating fluid conduits, wherein the twinned array include at least a closely adjacent and parallel pair of conduits extending from a heating fluid inlet entering the parallel pairs of conduits to a heating fluid outlet exiting the parallel pair of conduits, and wherein the parallel pair of conduits extend substantially linearly without crossing one another between opposed serpentine turns. Further, the parallel pair of conduits turn through the turns without crossing one another so that the twinned array lie substantially in a single plane overlaid by the upper sheet.05-13-2010
20090169307METHOD OF PREPARING A FOUNDATION STRUCTURE - This invention provides a method of preparing a foundation structure including the steps of forming foundation trenches in the ground; and heating the ground defining the trenches sufficiently to irreversibly change the properties of the ground defining the trenches. In the case where the ground consists primarily of clay, it is heated to a temperature above a level where the ground is baked into a brick-like consistency, wherein the structural water of crystallisation is removed and any carbonaceous material and Fe is oxidised. If the ground consists primarily of sand, it is heated to a temperature above its vitrification point wherein mullite (AI07-02-2009
20100322713MICROWAVE GROUND, ROAD, WATER, AND WASTE TREATMENT SYSTEMS - A microwave ground or road surface heating system that eliminates the need for preparation of the surface to be heated while preventing leakage of microwave radiation. The highly portable microwave heating system prevents leakage of microwave radiation via a microwave horn and sealing shroud configuration that seals the unit to the surface being heated.12-23-2010
20130094909SYSTEMS AND METHODS FOR COLLECTING AND PROCESSING PERMAFROST GASES, AND FOR COOLING PERMAFROST - Systems and methods for collecting and processing permafrost gases and for cooling permafrost are disclosed herein. A method in accordance with a particular embodiment for processing gas in a permafrost region includes obtaining a gas from a sacrificial area of a thawing permafrost region, dissociating the gas in a non-combustive chemical process, and circulating a constituent of the gas through a savable area of the thawing permafrost region to cool the savable area. In particular embodiments, this process can be used to cool selected areas of permafrost and/or create clean-burning fuels and/or other products from permafrost gases.04-18-2013

20090142145CLIP-ON CONNECTOR TO GEOGRID FOR SEGMENTAL BLOCK REINFORCED SOIL RETAINING WALL MECHANICAL CONNECTION SYSTEM - A clip-on connector adapted to be connected to a geogrid, comprising a base portion wherefrom at least one finger portion extends toward an opposite edge of the base portion, such finger portion defining, with the edge of the base portion, a clip, said clip having two arms respectively defined by said finger portion and by said base portion, the spacing between said two arms being smaller than the thickness of a portion of a geogrid whereon the connector has to be coupled, but such that said geogrid portion can be inserted between said two arms.06-04-2009
20100158618METHOD OF MODIFYING THE AXIS OF ROTATION OF THE EARTH - A method of modifying the Earth-rotation vector relative to the body of the planet or in inertial space by redistribution of the Earth's mass.06-24-2010
