Abstract
A method is disclosed for installing a pipeline made up of a plurality of pipe lengths or sections to extend along a predetermined underground grade in a trench. Pillow blocks are secured to the underside of the pipe lengths at predetermined intervals and the pipe lengths are respectively lifted with the pillow blocks suspended thereunder and sequentially placed in the trench with the blocks positioned thereunder on the grade surface in the trench. The pipe sections are then secured together to form a pipeline and the trench is backfilled. The pillow blocks may be adhered to the underside of the pipe sections or the pillow blocks may be loosely secured to the underside of the pipe lengths whereby the blocks will maintain a position by force of gravity under the respective pipe sections to which they are attached when the respective pipe sections are suspended in the air above ground.
