An example of performing the method.

To ensure the functions of lifting and lowering the drill extension rod (or breaker) on the rotary platform 4 installing the main winch with 2 drive breaker 20 (Fig.3) through a planetary gearbox, built inside of the drum. To perform auxiliary operations - installation of casing pipes and armorcast, lifting and lowering pile on the rotary platform 4 is mounted auxiliary winch 3 on designs similar principal. When using drilling equipment with an endless screw 11 auxiliary winch 3 may be used to transmit axial forces of the drill tool 10. Main and auxiliary winches, 2, 3 have the mode "free fall". In front of the turntable 4 hinged boom 7 with hydroc the mA 6 it from horizontal to vertical. Depending on the operations performed when the machine is in operation along the guide rails of the mast 5 is moved rotator 9, the transmitting torque of the drill tool 10 or breaker 20 for driving piles. Also in the guide mast 5 moves the carriage 12 by moving the rod of the hydraulic cylinder 13. Sequential movement of the cylinders of the lifting / lowering of the mast 5, lifting / lowering of the boom 7, the carriage 12 can be transferred to a mast 5 from a horizontal position (Fig. 4) in the vertical and back. The hinge faceplate 8 mast 5 by the arrow 7 allows leveling the mast 5 in the longitudinal and transverse plane through the serial or parallel displacement of the cylinders of the lifting / lowering of the mast 5. This operation allows to achieve strict verticality of constructed piles under conditions of uneven topography of the site, which is especially important in the construction of baraccuda piles.

In the case of the erection bored, baraccuda piles under the protection of the casing to the undercarriage of the truck 1 car attached casing equipment 14 to dive casing as extraction of soil boring tool 10 and sequential extraction area is South 15 telescopic drill rod 16, on the shank which is attached drill tool 10 (auger and bucket drills, core drills, pressure grapple, Widener). On rails of the mast 5 is moved by hydraulic cylinder rotator 9, for transmitting the necessary torque telescopic drill rod 16 and the drill tool 10. Through a system of locks and grooves on the key sections of the telescopic arm 5 and the torque on the spindle rotator 9 axial force of the hydraulic cylinder moving the rotator is transmitted to the drilling tool 10, which increases the efficiency of penetration of the soil. In the case of performing drilling operations using an endless screw 11, the immersion of the screw 11 into the ground at the expense of torque transmitted by the rotator 9, and an axial force that the screw 11 by means of the rotator 9, movable auxiliary winch rope 3. Filling the hole with concrete mix is in the process of extracting the screw 11 by means of reverse rotation through the hollow stem of the tool. For cleaning of the screw 11 from the soil during removal from the well at the bottom of the mast 5 is mounted device 17 cleaning of the screw 1, through which the screw 11, the received reverse rotation, osvobojdenie equipment 14 is removed; on the lower part of the mast 5 is mounted a support 19, the drill rod 16 is removed, the main winch rope fix endless screw 11, disassemble the hydraulic cylinder moving the rotator 9 and the main winch rope 2 is fixed to the rotator 9 through the block to move the rotator 9 down. In the case of pile driving equipment on the main winch rope 2 cars through the sheave pulleys hung from the hammer 20 impact mass of 4.5 tonnes, which, as the pile is moved along the guide rails of the mast 5. For pull-UPS and installation on the point of driving piles used the auxiliary winch rope 3. Verticality hammered piles is achieved by manipulation of the hydraulic cylinders 6 and is controlled by the corresponding device located in the cab.
