  • Patent number: 10337168
    Abstract: A trenching assembly used to cut a narrow trench in the ground surface. The trenching assembly comprises an attachment frame connected to a hood assembly via a linkage assembly. The attachment frame may be attached to the rear end of a work machine. A rotatable blade is disposed within a cavity defined by the hood assembly. The hood assembly may rotate about two different axes relative to the linkage assembly, and the linkage assembly may rotate about two different axes relative to the attachment frame. The trenching assembly uses a pair of accumulators to hydraulically rotate the linkage assembly about a horizontal axis relative to the frame in response changes in depth of the ground surface being cut by the blade. The linkage assembly may be hydraulically rotated using the accumulators without input from the operator.

    Abstract: A method is disclosed for installing a pipeline made up of a plurality of pipe lengths or sections to extend along a predetermined underground grade in a trench. Pillow blocks are secured to the underside of the pipe lengths at predetermined intervals and the pipe lengths are respectively lifted with the pillow blocks suspended thereunder and sequentially placed in the trench with the blocks positioned thereunder on the grade surface in the trench. The pipe sections are then secured together to form a pipeline and the trench is backfilled. The pillow blocks may be adhered to the underside of the pipe sections or the pillow blocks may be loosely secured to the underside of the pipe lengths whereby the blocks will maintain a position by force of gravity under the respective pipe sections to which they are attached when the respective pipe sections are suspended in the air above ground.

  • Patent number: 8974147
    Abstract: A device for controlling buoyancy of a buried pipeline, the device comprising a form placed atop the pipeline and a flexible strap extending around the form adjacent its top. The form may comprise a first trough located adjacent the first side of the pipeline, a second trough located adjacent the opposing second side of the pipeline, and a middle section with an inverted-U-shaped cross section such that the middle portion fits over the top of the pipeline and joins the first trough and the second trough. The troughs are filled with backfill when the pipeline is buried. Thus, when fully installed, the device may comprise the slot form, the strap, and the backfill. As the pipeline tends to rise, the straps deform, bringing the sides of the troughs inward and compressing the backfill therein. This prevents further upward movement of the pipeline.

    Abstract: The invention includes a method of making and using a flowable thermal backfill. The flowable thermal backfill has a low thermal resistivity, useful for filling trenches containing electrical cables and other lines that generate heat. The method includes process steps of blending ingredients of stone, sand and fly ash, making a flowable thermal fill by mixing the blended stone, sand and fly ash with Portland cement and water, and pouring the flowable thermal fill in an excavation containing heat generating lines, immediately after mixing the flowable thermal backfill.

  • Publication number: 20090185865
    Abstract: A method and apparatus for locating an underground object. The apparatus comprises an excavation head, a wave emitter, a receiver, and a processor. The excavation head is adapted for soft excavation of soil. The excavation head may use mechanical means to dislodge soil, pressurized air or water, or a combination of methods. The wave emitter, located proximate the excavation head, transmits waves into the soil. The receiver receives waves reflected by underground objects. Information about the reflected waves is processed by the processor to determine the location of the underground object.

  • Patent number: 7367748
    Abstract: A method of installing a non metallic pipeline segment along with a tracer wire segment using a horizontal directional drilling process includes positioning a horizontal directional drilling machine in a selected position on one side of the obstacle. A drill bit is attached to an end of a flexible steel pipe. The flexible steel pipe engages and is driven by the horizontal directional drilling machine that forces the drill bit and the flexible pipe from the first side of the obstacle to a second side of the obstacle thereby drilling a bore underneath the obstacle. The drill bit is removed and a reamer is attached to the end of the flexible pipe. An end of a pipeline segment along with an end of a tracer wire segment having a high carbon steel core and a copper cladding with a high density polyethylene jacket is attached to the reamer.

  • Patent number: 7351009
    Abstract: A fiber optic installation structure and method therefor includes a duct having an inner tube, at least one optical waveguide, and a jacket and is disposed within a channel of a paved surface. The jacket generally surrounds the inner tube. When the duct is disposed within a channel defined by a paved surface, a friction fit is created between the duct and the channel for holding the duct in place. Thereafter, a filling material is used for overlying the duct and at least partially filling the channel. In other embodiments, the jacket is capable of being compressed when installed into the channel. The duct may include an armor layer disposed between the inner tube and the jacket for protecting the inner tube. Moreover, at least one optical waveguide may be disposed within at least a portion of the inner tube of the duct and may be introduced after the duct is installed in the paved surface.

  • Patent number: 7246971
    Abstract: A stabilization system (10) for a section of submarine pipeline (11) comprising an end restraint (15) at each end of the section of pipeline and intermediate restraints (20) between the two end restraints (15) for limiting lateral movement of the pipeline (11) at the location of the restraints (15, 20). Each end restraint (15) is adapted to be secured to the pipeline (11) to transfer axial tension generated by lateral movement of the pipeline (11) to the seabed or ground on which the end restraint is installed. Each restraint (15, 20) comprises a pair of restraint faces (21) spaced apart to define a gap (23) through which the pipeline (11) can extend. Each restraint face (21) is configured to control curvature of the pipeline (11) during lateral movement thereof. A restraint device and a method of stabilizing a submarine pipeline is also disclosed and claimed.

  • Patent number: 7150116
    Abstract: An indicator device is used for locating an underground object, for example an underground pipeline, prior to surrounding excavation by a bucket excavator. The device generally comprises a panel member buried in the ground directly above the object. The panel member includes a distance marker mechanism indicating distance to a bottom end of the panel member to provide an indication to an operator of a bucket excavator. The panel member is formed in vertically stacked sections permitting individual sections to be removed sequentially as digging progresses. Each section is formed of folded tearable material which can be both unfolded to produce an elongate visible banner or torn to provide further indication to the excavator operator with regard to distance to the object to be avoided.

  • Patent number: 7070360
    Abstract: The invention provides a protective structure for a subsea installation. The protective structure comprises first and second body portions and a hinge member. The body portions are pivotally mounted to the hinge member such that at least one of the body portions may pivot relative to the other body portion. The body portions occupy a first configuration which facilitates transportation and/or deployment to the seabed and a second configuration in which the body portions are arranged to substantially enclose the subsea installation when the structure has been positioned over it. First and second locking means can lock the structure in the first and the second configuration respectively. Additionally the protective structure can allow access to the subsea installation when in use, by provision of a closable opening.
