    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.

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: 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.

    Abstract: Irrigation apparatus comprises a movable vehicle arranged to be steered along a required ground path and carrying a pair of laterally-extending booms each of which is pivoted to one side of a rotatable turret mounted on the vehicle chassis. Each boom carries spray or sprinkler nozzles spaced along their lengths and one or more spray nozzles at its tip, all connected to a supply of water, and the spray patterns of the various nozzles overlap one another in such a way as to ensure even total dosage of water delivered per unit area of ground as the machine advances. Means is provided for angularly reciprocating the turret and booms about the vertical axis of the turret. The vehicle may be connected by a trailing flexible hose pipe to a hydrant, or may have a power-driven hose reel on which the hose is wound and by which it can can be reeled in or unreeled whilst the vehicle is moving and with the hose either empty or delivering water. The flexible hose may also be of a longitudinally-seamed construction. The vehicle may alternatively run along a water-filled canal and pick up water from the canal as it moves.
