Claims

30 A tip located in the lower part of the barrel with end-to-end zeitrg and radial channels connected to the barrel channel and placed in a spring connected to the barrel channel, at least, a spring, the camera is placed in the upper part of the barrel and equipped with a piston with a rod and installed 1 in the upper the end of the barrel is an electromagnet nit, and the spring is installed around the guitar over the piston, the end of the piece is inserted into the cavity of the electromagnet and the nozzle is equipped with a check valve. The drawing shows a driving pile, a longitudinal section. The proposed design contains a trunk 1 with a central channel 2. In the lower part of the trunk 1 there is a tip 3 with through, central 4 and 5 radial channels. In the upper part of the barrel 1, a measure b is formed with smooth, for example metal, walls in which the piston 7 is mounted and connected to the rod 8 passed through the electromagnet 9. A spring 10 is located between the electromagnet and the piston 7. The case of the electromagnet 9 is fixed on the upper end of the barrel 1, for example with the help of bolt joints. For supplying water to the barrel 1, there is a branch pipe 11 equipped with a check valve 12. The proposed construction is as follows. In the pipe 11 through the check valve 12, and then into the central to the water 2 serves to wash out the soil water. After supplying electric voltage to the windings of the electric magnet 9 and under the action of the main pressure | Lenil water in the central channel 2, the rod 8 together with the piston. 7 is drawn into the electromagnet 9. In this case, the spring 10 is compressed to a certain force, which depends on the power of the electromagnet and the magnetized pressure of water. After the current of the electromagnet 9 is relieved of an electric voltage, the spring 10 is straightened, the core 8, together with the piston 7 in the chamber b, moves downwards, the check valve 12 is closed and the water with increased pressure along the central channel 2 openings 4 and 5 of the tip 3. Through the output nozzles of the central and radial channels 4 and water flows to the outer side surface of the tip of the tip 3 and, bla-. a year of increased pressure; blurs the soil around the tip 3. Then the cycle of the supply-reliance of the electric voltage to the electromagnet 9. and the feed-off of water into the central channel 2 is repeated. In this case, the operation of the device, the immersion of the pile and the erosion of the soil are carried out in a similar way. Powerful electromagnets (on the order of several and even several tons of tons) are capable of developing enormous water pressures. If it is necessary to drive a pile, a blow to the pile head can be carried out through the inventory pipe, -split around the electromagnet, or through a special cup-shaped cap (not shown). In this case, the electromagnet, the core, the piston and the spring can be used to immerse many piles installed at different times. The cva can sink under its own weight. In this case, in addition to the trunk, all units of the device can be used repeatedly for the immersion of other piles. The water pressure for soil erosion can reach several hundreds and thousands of atmospheres. The proposed design is easy to manufacture (due to the absence of complex assemblies), effective (due to the possibility of creating and maintaining a longer time pressure of water to erode the soil), able to sink under its own weight. Formula of invention The hammer pile, including the trunk with a central channel, communicates with a pipe nozzle for connection to the source of the working medium, located in the lower part of the barrel, the nozzle with through central and radial channels connected to the barrel channel, and A spring, which communicates with the barrel bore, is made in order to simplify the design, reduce material consumption and increase the efficiency of the pile, the chamber is placed in the upper part of the barrel and equipped with a piston with a rod and an electromagnet mounted on the upper end of the barrel. around the rod above the piston, the end of the rod is brought into the cavity of the electromagnet, and the nozzle is equipped with a check valve.
