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.
Abstract translation: 本发明是一种用于无管道铺设地下管道的方法和装置，其中犁犁通过拖拉机或绞车被迫穿过地面以形成地下隧道，以及连续长度的柔性套管，例如由 聚乙烯通过推进的犁耕的空心仓库进料，并铺设在鼹鼠后面的新形成的隧道中; 并且同时，通过包括一组气动分层驱动辊的驱动机器将长度的刚性管子纵向推进到隧道内以及在推进的犁耕机后面的套筒内，管道摩擦接合在该套管之间。 管道长度在地下隧道开始的套管内以与犁耕的行进速度协调的速度（例如借助于拖尾标记）被迫向前，使得管道长度的前端 紧跟着前进的痣的后面。 以这种方式，管道长度被推入到包围在保护套管中的最终位置，保护套管免受土壤水侵蚀。 如果需要，水泥浆可以注入到套管中以在管周围形成辅助保护涂层。

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.
