Kalinichenko, Registration Date 20-01-2014 Organization Donetsk National Technical University popup.description2 Proposed and experimentally proved refined analytical model of work and methods of engineering design of starting units of hydropercussion drill . An analytical model of the motion of the drill in the hole and its introduction into the face with " pecking " full-hole drilling . An analytical model and the computer modeling of the introduction into the soil of hydraulic drill with improved impact system based on its layout to a drill string . A refined method of calculating the duty cycle pile sampler with hydraulic drive. On this basis, developed new designs and hydraulic hammers drill pile sampler for sampling of soils in geotechnical drilling wells on the shelf Product Description popup.authors Калініченко Олег Іванович Каракозов Артур Аркадійович Комарь Павло Леонідович Парфенюк Сергій Миколайович Сьомка Олена Вікторівна Хохуля Олександр Володимирович popup.nrat_date 2020-04-02 Close
