ABSTRACT:
An improved method and apparatus for covering a pipeline wherein a fluid-solid fill mixture is continuously deposited over the pipeline and at least a portion of the fluid is continuously removed from the mixture while simultaneously and continuously forming the solid fill in a predetermined contour over the pipeline. In another aspect, an improved method and apparatus is provided in which the tendencies of erosional forces to uncover a pipeline are reduced by forming a consolidated layer over the exposed surface of the said fill.
