FIELD: transportation.
SUBSTANCE: lengthy pipeline section with insufficient depth of embedding is opened below the lower generatrix and undermined, undermined section of pipeline is supported by pipelayers. At the bottom of trench, starting from the point of the last support of opened area, they installed supports filled with sand soil with fraction size of up to 5 mm - shells made of rot-resistant material, onto which a pipeline is laid. Height of shell supports is controlled by extent of filling and number of levels. After pipeline is laid on support shells, pipeline is padded, filling soil is padded and trench is backfilled with soil.
EFFECT: improving reliability of pipelines.
