ABSTRACT:
A machine for compressively applying an outer cementitious coating received from a pressurized source on a continuous pipeline as well as on pipeline segments includes a cementitious material accumulating chamber with an aperture for receiving the pipeline thereinto. An injection manifold is in flow communication with the pressurized cementitious coating source and is oriented about and in flow communication with the accumulating chamber for evenly delivering the cementitious coating about the pipeline in the accumulating chamber. A frustoconical compression chamber having a wide and a narrow diameter concentrically joins the accumulating chamber at its wide diameter for receiving the pipeline and compressing the cementitious coating about and onto the pipeline. A forming chamber is concentrically oriented and adjoining the compression chamber at its narrow diameter for troweling and finishing the cementitious coating also having a coated pipeline exit aperture.
