Abstract:
A fluid device housing includes a lower fluid device housing portion and an upper fluid device housing portion each formed with mating members. Each of the mating members of the lower fluid device housing portion mate with a corresponding mating member of the upper fluid device housing portion to form an inclined channel. A connector member is arranged to fit at least partially around peripheries of the lower and upper fluid device housing portions. The connector member includes lugs that are received in the inclined channels.
Abstract:
Devices, apparatus, systems and methods for forming rolled up spiral shaped tubular inserts of interlocking seams of elongated strip material and for inserting the inserts into damaged channels such as culverts, sewer lines, pipes, and the like. The inserts are released to expand outward and unravel until the walls of the unraveling insert abut against interior walls of the damaged channel forming a protective interior wall for the damaged channel. One side of the insert strips can have a hook, and an opposite side of the strips can have a longitudinal groove wherein the hook attaches to and slides within the groove. Slidable surfaces such as bushings, Teflon coatings and O-rings can be used along the interlocking seams to allow for reduced friction as the strip materials are rolled into contracted positions and later expanded out.
Abstract:
The present invention relates to a conduit repairing material, repairing structure, and repairing method thereof, and particularly provides a repairing method for an existing conduit characterized by comprising using a plurality of reinforcing members capable of being carried in the existing conduit, assembling said reinforcing members into a hollow skeleton-like reinforcing body extending substantially along the inner surface of the existing conduit, attaching a plurality of inner face bars to the inside of the reinforcing body to assemble them into a tubular form along the lengthwise direction of the conduit, and injecting a curable infilling into the gap between the inner face bars and the inner surface of the existing conduit.
Abstract:
A plastic profiled strip (10) is provided for producing helically wound tubes or pipes, the strip (10) having female and male joint formations (13, 14) extending along opposite longitudinal margins thereof and arranged so that upon spirally winding the strip into a tubular form, the joint formations (13, 14) can be interlocked to thereby lock adjacent windings of the strip together, the male joint formation (14) comprising a hinged flap (15) which is flexibly connected to the strip (10) for hinging movement between a disengaged or unlocked position displaced from the plane of the strip (10) and a locking position wherein it interlocks with the female joint formation (13) of an adjacent winding of the strip (10).
Abstract:
A quick connector for forming a joint in a fluid line consists of a female connector body having a bore which receives a male member. A sleeve surrounds and is secured on the male member in close fitting relation with the male member and with the female connector body. A retainer extends between the sleeve and a radial face formed in the connector body to secure the male member in the connector body. A secondary retainer provides enhanced retention capability. An optional plug may be positioned in the bore entrance to prevent introduction of external contaminants.
Abstract:
A relining pipe for insertion inside sewer lines to repair them. The relining pipe is made up of a number of substantially rigid pipe elements (1), which are interconnected by pipe couplings, the pipe coupling including a female sleeve part (2) and a male locking part (3), at least one of these having a circumferential shoulder surface and the other having a stop surface pressing against the shoulder surface when the pipe elements are pressed against each other, and in the female part and the male part counterparts (5, 16) which snap-lock to each other in order to prevent the pipe elements from becoming detached from each other. The pipe element (1) has, as an extension of the male part (3) towards the female part (2), a shoulder ring (6) which is integral with the element and the outer diameter (D3) of which is approximately the same as the outer diameter (D2) of the female part. This shoulder ring has a shoulder surface (7) against which the stop surface of the outer edge of the female part (2) presses when the pipes are pressed together.
Abstract:
Underground frangible pipe replacement apparatus and methods for replacing an existing unserviceable pipe by first crushing the existing pipe entirely inwardly, or imploding it, to destroy it. The resulting shards are then forced outwardly into the surrounding soil, creating a bore large enough to accommodate a replacement pipe at least as large as, or large than, the old pipe. The new pipe is pulled into place substantially simultaneously with the expansion of the bore. The crushing tool includes a generally tubular main body and a plurality of longitudinally extending, tapered blades circumferentially disposed about the ID of the main body of the crushing tool. The blades taper outwardly and forwardly from near the midportion of the crushing tool. The crushing tool has a connecting rod at its center, including means for connecting the crushing tool to a motive force at one end and means for connecting the crushing tool to the expanding plug at the other end. A plurality of bell-engaging knuckles are disposed around the ID of the main body of the crushing tool between the blades. The rear end of the crushing tool is tapered inwardly and rearwardly. The expanding plug connects to the trailing end of the crushing tool, and includes a conical nose for expanding the crushed pipe fragments into the surrounding soil. The plug is pulled through the ground behind and along with the crushing tool, pulling with it the new pipe.
Abstract:
A utility bridge suitable for connecting offshore facilities such as offshore platforms is disclosed in which a plurality of helical pipelines provide flow communication between the facilities and relative movement of the facilities in response to environmental forces is provided for by helical pipelines with torsion expansion loops supported by a substantially rigid frame of the utility bridge which has means to prevent coupling of dynamic forces between the respective offshore facilities.
Abstract:
Method and apparatus for working on submerged pipeline means where multiple forces are exerted on each of a plurality of disconnected pipeline sections to effect alignment of these sections. On at least one section one of the forces functions as a fulcrum or restraining force while another force is operable to effect alignment inducing movement of a free end of the one section. Method and apparatus for effecting the laying of a pipeline where laying is implemented in conjunction with a transportable, submerged enclosure. The enclosure provides a gaseous environment for pipeline section joinder operations and may be at least partially flooded to facilitate the moving of the enclosure away from an already laid pipeline area.

[Also in Divisions F1 and F2] The delivery pipe 18 from a concrete or like pump 10 is connected to a conduit 30b forming part of a boom comprising sections 30 connected together. The boom may be raised and lowered and angularly adjusted by hydraulic means. As shown the pump and boom are mounted on a motor vehicle which has detachable hydraulic supporting struts 21. The first section 30 is permanently mounted on the vehicle and its conduit 30b may be bushed if subsequent conduit sections are of reduced diameter.
