FIELD: techniques for trench-free cleaning of inner surfaces of tubes, possibly of different-designation pipelines such as water supply conduits, sewage, pressure and gravity-flow pipelines in municipal service and also for cleaning drains of industrial plants, in oil production and other branches of industry.
SUBSTANCE: method comprises steps of mechanically separating deposits from pipeline surfaces and removing deposits out of cleaning zone. Plant for horizontally directed drilling is used for cleaning pipelines. Said plant has tie rods that are preliminarily introduced into pipeline. Expander and scraping brush are successively joined to tie rods. Then translation and rotation movements are imparted to tie rods and to devices joined with them for moving tie rods and devices joined with them in opposite direction.
EFFECT: enhanced efficiency of cleaning.
