FIELD: dredgers or soil-shifting machines for special purposes, particularly equipment for trenchless pipeline laying by driving method along with ground removal from hole. ^ SUBSTANCE: machine comprises pushing mechanism having frame on which power hydraulic cylinders, carriage with rack, ground removal mechanism, percussion mechanism with powered bogie and powered bogie movement mechanism are installed. Ground removing mechanism has annular blade. Above components are installed in pipe to be laid and made as inertioids. The inertioids include body secured to the bogie, annular running-track installed in the body and driving shaft eccentrically installed relatively the running-track. The shaft is provided with cut in which unbalance mass is freely located. ^ EFFECT: reduced metal consumption and operational costs due to simplified structure of percussion mechanism and powered bogie movement mechanism. ^ 4 dwg |
