Abstract:
Apparatuses, systems, and methods are provided for cutting a trench in soil or earth by driving a cutter tube member through the soil or earth, injecting compressed fluid into the tube member to break up the soil and drive it through the tube member along the flow of compressed fluid, imparting dynamic vibrational forces to the tube member to assist the flow of soil therethrough, ejecting the soil from the tube member, guiding and releasing media and/or filler material into the trench, and backfilling the trench with the ejected soil.
Abstract:
The present invention relates to a method for placing at least one duct/communication cable below a road surface in an area, said area comprising a first layer (L1 and a second layer (L2), said first layer (L1) being a road layer, such as asphalt or concrete, and said second layer (L2) being a bearing layer for said first layer (L1) and being located below said first layer (L1), said method comprising the steps of: cutting a micro trench in said area through said first layer (L1) into said second layer (L2); placing at least one duct/communication cable in said micro trench so that said at least one duct/communication cable is placed below said first layer (L1); and filling said micro trench so as to restore said road surface.
Abstract:
An extractor for removing agricultural tubing from soil of a field and related methods are provided. The extractor includes a frame and a pivot frame disposed on the frame. The pivot frame can have a pivot axis around which at least a portion of the pivot frame is pivotal. The extractor can include a first roller secured to the frame and a second roller secured to the pivot frame that is moveable by the pivot frame with the first roller being positioned closer to the soil than the second roller so that a tubing to be extracted is threadable under the first roller and over the second roller.
Abstract:
A casing puller includes a body and at least one arm. The body has first and second ends, at least one end connectable to a drill pipe. The body defines a longitudinal axis and sized for insertion into a casing pipe. The at least one arm is disposed on the body and moves between a stowed position and a deployed position. The at least one arm extends away from the longitudinal axis when in its deployed position and is arranged to engage an arm receiver defined by the casing pipe.
Abstract:
Apparatus and Method for Burying Elongate Member Apparatus for laying an elongate member in a trench, the apparatus comprises a main body portion; ground-contacting apparatus on which the main body portion is mounted and by which the apparatus may in use move over the ground; an elongate member moving device configured to move the elongate member from an initial position to a elongate member laying position; and a depressor attached to the main body portion and configured to guide the elongate member from its elongate member laying position to its in-trench location, the depressor having an elongate member entry portion and an elongate member exit portion, wherein the depressor is rotatable in use about an axis which is substantially parallel to the longitudinal axis of the elongate member.
Abstract:
A plough vehicle assembly is described. The plough vehicle assembly may be able to lay pipe or cable, and include a plough vehicle and a support mounted to the plough vehicle to support a pipe to be laid. The support may include a ring.
Abstract:
This invention relates to an improved apparatus and component for removing (and perhaps replacing) pipes, in particular underground pipes, as suitable for use in trenchless pipe removal methods such as that of WO 2008/071997. The invention provides a component which is securable to a cable, and which has a sleeve for surrounding an end of the pipe. The component has an opening through which a settable fluid may be delivered into the pipe in use. A surface of the component is adapted to seal the end of the pipe so that the settable fluid may not leak from the pipe before it has set. The apparatus comprises the component, a cable secured to the component, a winch and a settable fluid.
Abstract:
The invention relates to a method and an apparatus for introducing at least one pipe (2) for at least one optical cable (3) into a solid bed with the aid of a laying device, wherein at least one groove (1) is milled or cut in the bed and the at least one pipe (2) is inserted in the at least one groove (1), wherein at least one side wall (1′) of the at least one groove (1) is configured with a step (1″) for supporting a filler material (5, 6), by which after laying the at least one pipe (2) the possibly remaining volume of each groove (1) is filled, or a pipe (2) formed according to the groove (1). Preferably both side walls (1′) of the at least one groove (1) are configured with a supporting step (1′″), resulting in a substantially T-shaped cross-section of the groove (1). In addition, the friction between the at least one pipe (2) laid in the at least one groove (1) and the side walls (1′) of the at least one groove (1) can be increased so that emergence of the at least one pipe (2) of its own accord from the at least one groove (1) is prevented.
Abstract:
Presented is an underground cable laying apparatus that leaves virtually no visible scar in the turf under which cable, wire, line, hose, etc. is laid. The apparatus utilizes a pair of angularly displaced turf slicing wheels to slice and separate the turf forming a slit into which cable may be laid. A cable guide tube and roller properly place the cable within the slit. A pair of turf closure wheels close the slit in close proximity to the release point of the cable to ensure proper placement of the cable. The slit in the turf is gently and completely closed over the cable, leaving virtually no visible scar within the turf to upset the aesthetic beauty of a lawn. Further, the configuration and rolling action of the turf slicing wheels ensures that other underground cables will not be damaged if inadvertently encountered.
Abstract:
A pushing device which includes a frame supporting at least one powered train of wheels the drive surface of which is made from rubber for driving a plastics tubing through friction and for imparting thereto a continuous motion inside of a metal piping to be renovated, the invention being applicable to the renovation of systems of fluid-conveying buried metal pipings.
