FIELD: construction; applicable in repairs of floated and curved on float main pipelines. SUBSTANCE: method includes preparation of way along pipeline, filling of ground embankments on both sides of pipeline, laying of geotextile panels between embankments to overlap pipeline, filling of ballast on panels with their ends connected with each other. Ground humus containing layer is filled over panels. Preparation of way along pipeline located on side of chord contacting axis of curved pipeline and moved to calculated position is combined with ground filling, layer-by-layer compaction of ground between pipeline and way on calculated length with ground moving to under pipeline. Filling of ground embankment from opposite side of pipeline is carried out until reaching the calculated position. EFFECT: higher reliability of pipelines. 3 dwg
