| 20090185865 | SOFT EXCAVATION POTHOLING METHOD AND APPARATUS - 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. | 07-23-2009 |
| 20100074690 | SYSTEMS FOR THE SUBTERRANEAN SUPPORT OF UNDERGROUND CONDUITS - The present invention relates to a support system for supporting a conduit. In one exemplary embodiment, the system includes support beams extending across an excavated opening. For example, a pair of beams may be positioned to span the excavated opening with the opposing ends of the beams supported on the ground above the excavated opening. Support rods may be positioned to extend through and/or from the beams and into the excavated opening. In one exemplary embodiment, the support rods include a J-hook configured for receipt within an opening in sections of curved sheet pile positioned beneath a conduit. By using a plurality of rods, the individual sections of curved sheet pile may be connected to the beams to provide a support structure for the curved sheet pile and, correspondingly, the conduit extending above the curved sheet pile and below the beam. | 03-25-2010 |
| 20100080656 | SYSTEMS AND METHODS FOR PROTECTING SUBTERRANEAN STRUCTURES - Systems and methods for protecting a subterranean structure are provided. The method can include, but is not limited to, removing at least a portion of earth disposed above a subterranean structure to provide a foundation; depositing an isolation layer above the subterranean structure; and depositing at least a portion of the removed earth, a fill material or both to at least partially cover the isolation layer. | 04-01-2010 |
| 20110158747 | METHOD FOR PROTECTING SUBMARINE CABLE AND SUBMARINE LONG TUBE - At a location where a submarine cable | 06-30-2011 |
| 20120020738 | Systems and Apparatus for Protecting Subsurface Conduit and Methods of Making and Using the Same - Systems and apparatuses protect subsurface conduit. Specifically, the systems and apparatuses protect subsurface conduit by disposing one or more rigid caps over a length of the subsurface conduit under a roadway for decreasing and/or eliminating impacts and/or damage to the subsurface conduit caused by automobiles and other vehicles utilizing the roadway. Methods of making and using the same are further provided. | 01-26-2012 |
| 20120224923 | DEVICE FOR COVERING AND PROTECTING BURIED PIPES OR CABLES - The invention relates to a device for covering and protecting buried pipes or cables, including a substantially planar plate ( | 09-06-2012 |
| 20120328370 | Laying Machine - The present invention relates to a laying machine for laying at least one flexible casing or tube, cable or wire including: a blade arrangement ( | 12-27-2012 |
| 20130011198 | METHOD AND DEVICE FOR INTRODUCING A PIPE FOR OPTICAL CABLES INTO A SOLID LAYING FOUNDATION - The invention relates to a method and an apparatus for introducing at least one pipe ( | 01-10-2013 |
| 20130216313 | MACHINE FOR SAWING TRENCHES AND PLACING DUCTS/CABLES - The present invention relates to a machine arranged for sawing micro trenches and placing ducts/communication cables in micro trenches, said machine comprising a saw blade arranged for sawing a micro trench in an area; said machine further comprises a stabilizing device arranged for stabilizing the walls of said micro trench when placing ducts/communication cables into said micro trench, said stabilizing device being positioned immediately behind said saw blade in said micro trench, and said stabilizing device comprising guiding means for guiding at least one duct/communication cable when placed into said micro trench. | 08-22-2013 |
| 20130315672 | METHOD AND APPARATUS FOR PROTECTING PIPE INSTALLED UNDERGROUND - A borehole pipe protection apparatus includes a sheet of material having an inner surface and an outer surface and a longitudinal direction and a width direction defined by two edges of the sheet along the longitudinal direction. A fastening structure is configured to join the two edges to form a seam as the sheet of material is wrapped in the width direction around a pipe that is configured to be installed into the borehole to form a sock along the longitudinal direction. The sock is configured to be installed in the borehole with the pipe about which it is wrapped, yet to remain for a service life in non-bonding contact with the pipe. A method for protecting pipe during and after insertion into a borehole is also described. | 11-28-2013 |
| 20140037383 | TRACER WIRE INSTALLATION DEVICES AND METHODS FOR TRENCHLESS UTILITY REPLACEMENT - Devices and methods for trenchlessly replacing an existing utility pipe with a replacement pipe and a tracer wire are described in this application. A replacement pipe may be joined to the head adaptor of a trenchless splitter tool with a tracer wire being trapped between them, resulting the tracer wire extending from within the replacement pipe through a joint to the exterior of the replacement pipe. A protective cap (or deflector) may be placed of the portion of tracer wire extending from the joint. The splitter tool may then be introduced into and travelled along the existing pipe, splitting and displacing the existing pipe, and placing replacement pipe and tracer wire along the path of the existing pipe, thereby functionally replacing the existing pipe with a replacement pipe and a tracer wire. Other embodiments are described. | 02-06-2014 |
| 20150086273 | METHOD OF INSTALLING A PIPELINE AND PIPELINE SUPPORT SYSTEM - 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. | 03-26-2015 |
| 20160025257 | Covering for Underground Pipes and Related Methods - The present invention relates to the protection of underground utilities, such as pipes and cables. The invention provides a protective coating for underground pipes and cables that is flexible, waterproof, durable, and cable of withstanding many different stresses. | 01-28-2016 |
