The invention relates to the field of construction, namely, to the piles with a drop-down blades, and can be used in the construction of various structures on pile foundations.

Known pile, comprising a hollow barrel with the hole in the wall, retractable blades and accessories for the nomination of the blades, and the barrel is fitted established in its cavity transverse diaphragms with through holes, each blade installed in the cavity of the barrel freely between adjacent apertures, with each device for extension is made in the form of thrust, passed through holes in the respective apertures.

The closest technical solution design implementation of the invention is the opasti with flanges on the tail section and tapering in the leading part.

Known pile does not have sufficient operational reliability, because of the need to use passaredo for the nomination of the blades, increasing the probability of damage and deformation of the pile and its elements.

The problem to which the invention is directed, is to increase the bearing capacity of piles and its operational reliability.

The technical result from the use of the invention is effective compaction of soil in the area adjacent to the pile, corrosion resistance and high load-carrying capacity pull out.

This technical result is achieved in that the anchor pile, comprising a hollow barrel with bottom and walls having spaced tiers of Windows, and a sliding window of the blades in the form of inserts with flanges on the tail section and tapering in the leading part, according to the invention is equipped located in the upper part of the barrel, having a concave upper and lower surfaces of the base platform-collar-through socket for connection to the vacuum pump, cover, overlapping the reference area-collar on top of and connected to the bottom of the barrel by means of a cord, and is located in the cavity of the barrel IPN is kerna pile, the incision of Fig.2 is a plan; Fig.3 - section a-a in Fig.1; Fig.4 - blade insert, cut, and Fig.5 - section b-B in Fig.4.

Anchor pile contains placed at the top of the pile supporting platform-collar 1, covering the hollow shaft 2 with a bottom 3 and walls 4, in which the tiers are open 5. In the latter placed the blade inserts 6, made in the form of hollow cones with flanges 7 and projections 8. The ground-collar 1 is provided with a socket 9 for connection to the vacuum pump. Inside the barrel 2 is placed a spiral valve 10 and the tie bars 11 connected to the bottom 3 and the lid 12, overlapping on top of the pad-collar 1.

The pile is made by stamping, for example, from a polymeric material. When this tapered blade inserts 6 can be made of metal and stiffeners. To prevent soil from entering the barrel 2 box 5 before installing piles may be protected by a metal foil.

Before installing piles in the soil perform the recess under the base pad-collar 1 and drill hole to a predetermined depth. After you install support point-collar in the well is lowered pile and is precipitated by hand. Then, for example, by hydraulic manipulation is lnewt concrete, before the end of the hardening which produce the tension of the strand 11 and connect it to the cover 12. The pipe 9 is connected to the vacuum pump and create the necessary negative pressure under the reference area-collar 1, resulting in effective sealing of the soil adjacent to the pile area.
