FIELD: construction engineering; erection and repair of pipe lines. SUBSTANCE: cleaning unit is moved inside pipe line forming jets of liquid over periphery which act as electrohydraulic or pneumohydraulic impact. Products of cleaning are mixed with mortar and after application of mortar on inner surface of pipe line, screened hose is forced into mortar. Invention contains recommendations for technological modes and choice of materials. EFFECT: enhanced reliability of pipe line due to application of storage and elastic coat. 23 cl, 10 dwg
