    Abstract: A pipe cluster unit comprises a plurality of plastic pipes arranged parallel to one another and being in mutual engagement with one another along longitudinal lines of contact to form a pipe cluster and a cover layer bonded to external surface portions of the pipes. The cover layer connects adjoining pipes to one another by bridging the adjoining pipes at locations spaced from respective lines of contact between adjoining pipes.

    Abstract: This invention provides apparatus and a method for laying flexible irrigation tubing underground, the apparatus comprising a plow attached to a frame, means located on the frame to support and unreel a spool of flexible tubing, a rigid tube affixed to the frame adapted to accept the flexible tubing at its upper end and bent so that its lower portion extends rearward of the plow generally parallel to the ground and in the trench dug by the plow, hillers affixed to the frame adapted to force the dirt plowed by the plow back into the formed trench immediately behind the rigid tube, and a compacting means attached to and trailing the hillers to compact the dirt into the trench, provided that the trailing end of the rigid tube extends rearward to a point behind the point of compaction of the compacting means such that, in operation, as the apparatus is pulled across the ground and the flexible tubing is drawn into the rigid tube, the flexible tubing exits the trailing end of the rigid tube and is laid into the underground tunnel which is formed by operation of the component parts of the apparatus.

    Abstract: The invention is a method and apparatus for the trenchless laying of pipe underground, in which a mole plough is forced through the ground by means of a tractor or winch to form an underground tunnel, and a continuous length of flexible sleeving, for example made of polythene, is fed down through the hollow coulter of the advancing mole plough and is laid in the newly formed tunnel behind the mole; and at the same time a length of rigid pipe is thrust forwards lengthwise into the tunnel and within the sleeving laid behind the advancing mole plough, by means of a driving machine including sets of pneumatic-tiered driving rollers between which the pipe is frictionally engaged. The pipe length is forced forwardly within the sleeving from the start of the underground tunnel at a speed which is coordinated with the speed of travel of the mole plough, for example by means of a trailing marker, so that the leading end of the pipe length follows closely behind the rear of the advancing mole. In this way the pipe length is pushed into its final position enclosed in the protective sleeving which protects it against corrosive attack by soil water. If desired cement grout may be injected into the sleeving to form an auxiliary protective coating around the pipe. The specification also describes a modified form of mole plough designed to be used in a submerged position for pipe laying by the described method in a river bed or estuary bed, and to be rendered buoyant by means of compressed air for navigation purposes. This mole plough has a hollow framework and pivoted front and rear undercarriages with pivoted hollow rollers which also act as floats.

    Abstract: AN APPARATUS FOR INSTALLING A SUBTERRANEAN PIPELINE IN AN ELONGATED EARTHEN TRENCH. THE APPARATUS INCLUDES A MOBILE HOUSING OPERABLE TO BE MOVED ALONG AND WITHIN THE TRENCH. STRUCTURE IS PROVIDED FOR GUIDING INDIVIDUAL SECTIONS OF PIPE INTO LONGITUDINAL ALIGNMENT WITH THE PIPELINE AND MECHANISM IS PROVIDED FOR SHIFTING THE SECTIONS INTO ABUTMENT WITH THE PIPELINE AND FOR MAINTAINING THE PIPELINE IN COMPRESSION TO PREVENT THE INDIVIDUAL SECTIONS FROM MOVING SUBSTANTIALLY AFTER THEY ARE EMPLACED. THE STRUCTURE AND THE MECHANISM ARE MOUNTED FOR RECTILINEAR VERTICAL MOVEMENT WITHIN THE HOUSING SO THAT THE GRADE OF THE PIPELINE MAY BE CLOSELY CONTROLLED IRRESPECTIVE OF THE GRADE OF THE BOTTOM OF THE TRENCH. ALSO INCLUDED IS MEANS FOR PREVENTING DEVELOPMENT OF SUCTION BETWEEN THE HOUSING AND THE TRENCH WHEN THE LATTER IS MOIST.

    Abstract: A method of laying lengths of underground pipe, for example drainage pipes, by forming an underground tunnel by means of a mole plough, and drawing a length of pipe into the tunnel into its required final position, characterized in that a liquid slurry is injected into the tunnel formed by the mole before the pipe length is drawn into the tunnel, the slurry serving to lubricate the pipe during its travel along the tunnel. Preferably the principal ingredient of the slurry is Bentonite. The pipe may be towed directly behind the mole and drawn progressively into the tunnel as it is formed or the pipe may be drawn into the slurry-filled tunnel after the mole plough has completed its traverse.
