Beschreibung
Zusammenfassung:	FIELD: pipeline construction technology. SUBSTANCE: method includes preparation of traffic way along pipeline placement area, delivery of backfilling soil to pipeline placement area, placement of geotextiles material on the pipeline and swamp surface, covering of geotextiles material with soil, overlapping of backfilling with geotextiles material, connection of geotextiles material edges and covering of geotextiles material perimeters with soil. Geotextiles material are placed with lap portions along length, backfilling is performed in separate portions, interacting along slanting surfaces of natural slants, overlapped by lap portions and longitudinal edges of geotextiles material with following connection of said portions. Backfilling height is dependent on variable swamp depth. Mathematical formula for calculating height is provided. EFFECT: increased pipeline reliability. 4 cl, 4 dwg
