The invention relates to the field of construction, in particular to pile structures.

Prismatic piles are known that are immersed in the ground by means of driving 1. However, when such piles are driven into strong soils, their heads are broken by diesel hammers, which makes it necessary to block additional piles - doublers.

Piles are also known, including a barrel with a channel and a tip with a device for feeding the working medium to the bottom 2. However, these piles are not sufficiently effective when diving, since water is used as the working medium for the development of a well.

The aim of the invention is to increase the efficiency of immersion due to the use of a supersonic gas stream as a working medium.

For this, in the pile, which includes a barrel with a channel and a tip with a device for feeding the working zone to the face, adaptations for supplying the working medium to the face are made in the form of a Lawn jets connected to the cable in the barrel rigidly connected to the shaft.

FIG. 1 shows a pile at the time of its plunging into the ground, a general view; in fig. 2 — node I in FIG. one.

Sva consists of a barrel 1 with a channel 2 and a tip 3 with a prienosobleemiey 4 for nodachi working medium on the face, with a wave in the form of a working head with Lawal 5 nozzles, connected with channel 2.

Pile diving is carried out as follows.

The pile is mounted on the slings 6, the channel 2 is connected via a hose 7 with a high pressure source (receiver) 8. After the high pressure gas is supplied from the receiver 8 through the hose 7 through channel 2 to the working head 4, the gas having flowed out of the working head acquires supersonic speed the nozzle nozzle Laval 5 and, affecting the face, destroys it. As the pile collapses, it falls to the design depth. In unstable soils, after the penetration, the gap between the pile and the wall of the formed well is drawn in by the soil. In stable rocks, this gap is covered with soil.

The use of the described pile is most expedient in those cases when it is necessary to cut through layers of strong soils.

In this case, it is possible to immerse without using shock loads and destroying the head part of the pile, and it also eliminates the need to cut the heads of the pile to the design level, since the pile is
