Abstract: To obtain horizontal wells impassable sections of diameter up to 600 mm can be applied vibro-impact methods of drilling using pneumodrilt. Operating experience these machines in the Soviet Union, Russia, the near and far-abroad countries it has shown the efficiency of the technological process of the construction of underpasses by trenchless methods. The paper considers the issues of obtaining horizontal wells by the method of vibro-impact puncturing using pneumodrilts; the technological scheme of production work and an example of its practical application. The construct of the self-propelled dragheads of cyclic action in which they are delivery to a face and soil excavation by the actuator, which applies a pneumodrilts. Developed two types dragheads with capacitive and cut-off tools. To determine the total time of excavation core by dragheads of cyclic action in the article shows the dependence of the duration of the cleaning pipe-casing from its length, which can be used in the creation of normative-technical documentation, the estimated norms and pricing rates. The spread of technology vibro-impact puncturing for performing excavating works is limited by low production volumes powerful pneumatic percussion machines, the lack of serial production tooling for clogging of pipes and equipment for soil excavation

Key words: vibro-impact puncturing pneumatic percussion machine pipe-casing remove a soil core the draghead of cyclic action
