FIELD: machine building. ^ SUBSTANCE: procedure consists in laying pipeline into ditch, also, pipeline is laid from bundle on drum, in soil fill, and in connection of straight branch with flexible sleeve through coupling. The pipeline is directed through the straight branch on a bottom of the ditch and is transferred along the ditch by means of a device for lengthwise transfer. Soil is back filled over the place of the straight branch location; also, length L of the straight branch and diameter D of the pipeline bundle are chosen from ratio: L>1.5ÇD. ^ EFFECT: raised efficiency and reduced curves at laying pipeline in ditch. ^ 2 dwg, 1 tbl |
