    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.
