SUBSTANCE: invention relates to laying of main lines in settlement soils. According to proposed method, trench is dug out and artificial base is formed after which pipeline is laid and trench is filled with soil. When preparing the base, widenings are dug out at designed pitch at level of trench bottom symmetrically relative to longitudinal axis of pipeline. Prior to laying pipeline, load-bearing diaphragm made in form of plate is placed on bottom of each of widenings with overlapping trench bottom in cross direction. Longitudinal edges of said diaphragm are furnished with anchoring members. Filling of trench is carried out without displacement of anchoring members of load-bearing diaphragms towards pipeline. For this purpose filling of widenings is done starting from ends of pipelines remote from pipeline and symmetrically relative to pipeline. Load-bearing diaphragm is manufactured of cloth durable in soil, and its edges longitudinal relative to pipeline are furnished with eyes. Anchoring members are made of rot-resistant materials in form of stretched articles fitted in eyes of load-bearing diaphragms. Invention provides description of pipe laying method depending on level of ground water in trench.

EFFECT: improved reliability of pipeline.
