Abstract: A machine for arrangement of enlarged piles relates to civil engineering and can be used for arrangement of in situ piles. Its basic structure includes a guide frame and counterweights, and the hydro-mechanical drive of stepping operation includes the insertion and anchoring hydro-cylinders, and the piercing unit is arranged of pilot and reaming sections placed concentrically, those move together or with alternation through mechanism of alternating operation from insertion hydro-cylinder. The anchoring hydro-cylinder is connected to the anchor elements through telescopic mechanism. The pilot section includes an opening mouthpiece, its sectors are in radial-rotary way connected to the end of the tubular body and in folded state are fixed with lugs on the mouthpiece of the axial beam, and in its folded state, at its end a lifting loop is provided. The sectors are the bottom of the cavity for a portion of curing mix, to the body branches are connected, those are connected to a hook of cable-block system of load-lifting mechanism through extraction mechanism, and the axial beam is fixed to the branches in folded state of sectors through fixation mechanism, and insertion and anchoring hydro-cylinders are hinged to the body of actuator, this holds the hydro-connection discs with telescopic elements, at that the support disc is installed with possibility of connection with the guide frame, the insertion disc is attached to intermediate frame, this is hinged to the rod of hydro-cylinder, and the anchor disc is hinged to the rod of the anchoring hydro-cylinder, at that in the state of folded sections and hydro-cylinders the insertion disc rests on the branches to the body of the pilot section and is connected to the body of reaming section, the bearing disc rests on the body of reaming section, and the anchor disc is connected to the mechanism for moving out the anchor elements, those are placed in perimeter of the body of the reaming section in axial planes, beginning from the mouthpiece. To the body of actuator a mechanism is installed for restriction of moving out anchor elements, to dimension that is minimally enough for partial separation of the surface of the body of reaming section from the surface of the shall formed of compacted earth formed at driving in, and to the guide frame, near the lower end, with threaded joint clips are installed with possibility of interaction with long lugs provided on the surface of the surface of the body of reaming section for its fixation, and the guide frame, near the clips, a telescopic slide for piercing unit rest is installed, this includes folding disc the inner surface of which is arranged as a truncated cone, with possibility of folding the sectors of the mouthpiece of pilot section, and at the upper end of the guide frame a loop for lift with possibility of radial-rotary motion to the side of placement of rigidity ribs is fixed, thus to the side opposite to the side opened for removal of the actuator and the pilot section, for temporary arrangement of those, out of the boundaries of the guide frame, holders are connected to it, at that the holder of the pilot section includes folding disc as well, and on the holder to the actuator the end switch for switch off of the hydro-drive is installed, this is locked from the restrictor installed on the branch of the guide frame with possibility of motion along the deepening scale, at that the restrictor is connected to cable-clock system of its displacement and fixation at set mark of the immersion scale.
