FIELD: construction.
SUBSTANCE: method comprises turning the hose made of fiber material impregnated with a solidified binder enclosed in the flexible polymeric shell inside out, moving the hose inside the pipeline, expanding the hose, and pressing it to the inner side of the pipeline under the action of water pressure to the inner side of the turned out hose. The water column is simultaneously affected by the pulses generated by the generator-source of the hydraulic impacts submerged in the water. The amplitude and frequency of the hydraulic impacts change by changing the air pressure at the outlet of the compressor connected with the pulse generator.
EFFECT: simplified method.
