Rusanov V. Substantiation of rational technological regimes shock-vibration drilling of submarine holes

The shock-vibration sampler. Investigate the conformites to action of sampler, ground the the parameters of drilling used for taking soil samples. Apparatus of mechanics, hydro-dynamics, experimental planning. The mathematical descriptions of working cycle hydro-shocking mechanism is made. The model of liquid movement in cylinder of pump block is elaborete. The rational technological parameters of drilling holes in loose soil are established. The results of theoretical researches were confirmed during the laboratory tests. The technological parameters were tested in indystrial conditions. Quality and productivity of taking samples is raise. Drilling of holes.
