A method and apparatus for constructing a tubular assembly 40 comprising an inner portion (24) and a further portion (23) surrounding the inner portion. The inner portion (24) comprises reinforcement (37) and the further portion (23) being formed from a strip (50) of material comprising two opposed longitudinal marginal side portions (53). The apparatus comprises an assembly station (220) comprising a wall (253). The apparatus comprises means for advancing the inner portion (21) along a first path (231) extending passed the wall (253), and means for advancing the strip (50) along a second path (232) and causing the strip to encircle the wall (253) and thereby wrap about and surround the inner portion (21). The apparatus further comprises means (321) for introducing resinous binder into the reinforcement (37) as the strip (50) is being wrapped about the inner portion (21).

Techniques for implementing and/or operating a pipe deployment system that includes pipe deployment equipment, in which a pipe drum having spooled thereon a pipe segment is to be loaded on the pipe deployment equipment, and a pulling device to be secured to an unspooled section of the pipe segment. The pulling device includes a device body having a first body arm and a second body arm, in which the device body is to be disposed around the unspooled section of the pipe segment, the first body arm is to be secured to a first cable branch, and the second body arm is to be secured to a second cable branch. The pulling device includes a first pipe grabber secured to the first body arm and a second pipe grabber secured to the second body arm such that the second pipe grabber and the first pipe grabber open towards one another.

The present application relates to a cable laying device. The cable laying device is used for transporting and laying a cable, and comprises: a base section and an extension section with adjustable length, wherein the extension section and the base section are connected to each other at their longitudinal ends and are moveable relative to each other, the base section is configured to include one elongated cable carrier, and the extension section is configured to include at least one elongated cable carrier, wherein for the base section and the extension section, the cable carrier a carrying portion for holding the cables, wherein the carrying portion enables the cables to move along with the cable carriers of the base section and the extension section, and wherein the height of the base section and/or the extension section can be adjusted.

A pipe retrieval machine includes a frame defining a decoupling region and a travel axis and a transporting mechanism supported on the frame. The transporting mechanism has a first gripping structure adjacent an infeed end of the machine and a second gripping structure adjacent an outfeed end of the machine. The decoupling region is between the first and second gripping structures. The machine has a drive system to move the first and second gripping structures at a steady state speed to direct a pipe along the travel axis. The pipe retrieval machine includes one or more safety features to stop the drive system either automatically or through manual action, one or more safety features to inhibit or prevent damage to components of the decoupling region in the event of a malfunction, or both. Methods of operating a pipe retrieval machine include any of the operation procedures, method steps, safety features, and/or functions as described and in any combination.

A segmental tube section structure having a length and a circumference, the segmental tube section structure including, a plurality of tube segments extending the length in a longitudinal direction of the segmental tube section structure and extending in a circumferential direction of the segmental tube section structure, wherein each tube segment of the plurality of tube segments extends in the circumferential direction to span an arc of the circumference of the segmental tube section structure, wherein each of the plurality of tube segments is connected to adjacent tube segments of the plurality of tube segments in the circumferential direction to form the segmental tube section structure, wherein at least one of the plurality of tube segments comprises an attachment structure to accommodate a vehicle track assembly, and wherein each of the plurality of tube segments is formed of a steel plate.

A hose stand assembly includes a plurality of rings that is each positionable around a fuel hose. A plurality of legs is each of the legs is pivotally disposed on a respective one of the first portion and the second portion of a respective one of the rings. Each of the legs is positionable in a deployed position having each of the legs extending downwardly from the respective ring. In this way each of the legs can support the respective ring above a support surface. Thus, the rings and the legs support the fuel hose above the support surface when the fuel hose is extended through the respective ring. Moreover, each of the legs associated with each of the rings has a unique length with respect to each other to orient the fuel hose at a downward slope for enhancing the flow of fuel in the fuel hose.

A pipe loosening device and methods are shown. In one example, the pipe loosening device enables a method wherein a pipe to be replaced is deformed but not burst, and a portion of a sidewall of the pipe is forced outward into the surrounding soil to compact a local region of the surrounding soil and loosen the existing pipe. The pipe may then pulled from the ground along an axis of the pipe.
