FIELD: construction.
SUBSTANCE: group of inventions relates to construction work technologies and may be used for draw-in routing of underground pipelines. According of the first version of invention, the method provides for developing pilot well between operating pit and receiving pit along the design axis of the routed pipeline and simultaneous routing of drill rod inside the above pipeline. Then, the drill rod is connected with driven element. After that, the pilot well is widened to the design diameter by ground breaking up with driven element. The breakup products are transported by means of treating agent flow through the pipeline installed in the widened part of the well, which is then connected with driven element and rotated with it around longitudinal axis. The second version of the invention differs from the first one in pipeline installation inside the drill rod.
EFFECT: improvement of work performance reliability and productivity due to forced mixing of breakup products and their high concentration in treating agent.
