ABSTRACT:
Apparatus for and a method of laying a pipe line utilizing an advanceable shield composed of a set of parallel elongate planks supported for longitudinal movement by a frame. These planks have cutting edges and can be shifted individually or in groups by means of rams coupled between the frame and the planks. This shield serves to excavate an open-topped trench and behind the shield is a receptacle connected to move with the frame. This receptacle is a substantially closed vessel resembling a bath tub in cross-section with an open top permitting a pipe section to be lowered therein. A rear end wall of this receptacle has an opening therein which enables the pipe section to be joined up to the end of another pipe section previously installed at the end of the pipe line.
