FIELD: pipe transport.
SUBSTANCE: invention relates to construction of pipe transport and it can be used at repairs of underground pipelines. Using hydraulic excavator soil is dug out of trench: soil over buried pipe is removed, soil near buried pipe is dug out, soil under buried pipe is dug out using excavator set into operation from its own supply source or from supply source of hydraulic excavator drive. Excavator digging out soil under buried pipe is towed by hydraulic excavator. Excavator contains body, right-hand and left-hand carrying frames secured for turning on body and cutters fastened on lower ends of carrying frames. Cutters rotated by hydraulic drive are pointed to each other and provided with outer surfaces into which cutting members are fitted.
EFFECT: enlarged range of technical means.
