FIELD: construction engineering; erection of pipe lines in thawing permafrost soils and in flooded areas.
SUBSTANCE: proposed method includes ditching at trench with widened areas located at definite distances and pipe line is laid on bottom of trench. Pipe line is covered with flexible rugs and bottom of trench at widened areas is also covered with rugs; edges of rugs are fastened in widened areas and trench is filled. Used as anchor member are cylindrical textile containers placed in lugs of flexible rugs in parallel with pipe line and filled with soil. Prior to fastening the edge sections of flexible rugs, each of them is tightened at fixation of tension; preliminary tension of edge sections is effected during filling the widened areas and trench soil ensuring contact of flexible rugs with bottom of widened areas and trench. Filling the widened areas and trench is performed in direction towards pipe line, symmetrically relative to it.
EFFECT: enhanced reliability of attachment of pipe line at 0required marks.
