The closest technical solution known to the invention is a method for soil compaction, which perform SL is blowing procedure: a hollow casing pipe and tapering to the tip, which contains the petals, hinged to the hollow casing pipe, plunge into the ground to a predetermined depth, fall asleep protoplasts mixture into the internal cavity of the tube and tapering tip, raise the hollow casing pipe and thereby provide disclosure of hinged petals, after removing the casing from the ground provide a folding hinged lobes tapering tip (see SU 723026 And, E02D 5/46, 01.03.1978).

When soil compaction, have a stronger interlayers, hinged petals tip may be damaged.

The objective of the invention is to increase the strength of the tip and its petals.

This technical result is achieved by the fact that according to the method for soil compaction, which perform the following actions: a hollow casing pipe and tapering to the tip, which contains the petals, hinged to the hollow casing pipe, plunge into the ground to a predetermined depth, fall asleep protoplasts mixture into the internal cavity of the tube and tapering tip, raise the hollow casing pipe and thereby provide disclosure of hinged petals, after removing the casing from the ground provide a folding hinged petals in narrowing the different head, tapering head is equipped with at least one blade fixed on the hollow casing pipe, after the first dive into the ground casing with cap and extract perform at least one subsequent immersion so that the cross-sectional area protoplasma mixture obtained after the first dive, overlaps in any way the subsequent dive.

Through supply of tapering of the tip, at least one blade fixed on the hollow casing pipe, increases the strength of the tip and its petals. This allows you to compact the soil with a stronger interlayers, as well as to re-seal the previously compacted soil.

Subsequent immersion can be performed with an eccentricity from the axis of the first dive is less than the lateral dimension of the cross section, for example less than the diameter of the cross section, this dive.

Suitable two subsequent dives to do with the formation of the hive from protoplasma mixture.

It is possible to perform the immersion of the casing with the tip in the center of the formed Bush.

Axis dives casing with the tip can be positioned at equal distance from each other and at a distance equal to their radius from the center of the Bush.

At least one subsequent immersion of the casing with CSOs is Ofcom it is acceptable to perform at the same place, that first dive.

The invention is illustrated by drawings, which depict: 1 - installation for compaction of soil, petals tip are in the folded position; figure 2 is a view of a hollow casing with open petals tip; figure 3 is a top view of the formed piles of protoplasma mixture.

Installation for soil compaction includes a hollow casing pipe 1 (see figure 1) and tapering head 2, for example a conical tip. The hollow casing may be made cylindrical, prismatic, and may consist of several series-connected parts of the same or different forms. Made conical tapering head 2 contains a triangular hinge installed petals 3 (see figure 2), each of which is fixed by means of the hinge 4 on the hollow casing pipe 1, so the petals 3 may be disclosed, as shown in figure 2, and formed in a conical tip. Tapering head 2 (see figure 1) equipped with at least one blade fixed on the hollow casing pipe 1. In addition, the tapering tip 2 only part of the petals can be fixed hinge, and the other part is fixed. For example, the end of the hollow cylindrical pipe can be made in the form of a prism or parallelepiped, this kantserova can be fixed movable hinged petal and fixed rigidly fixed petal, together forming a tapering head 2.

The described apparatus is used in the method for soil compaction, which perform the following actions: a hollow casing pipe 1 and a narrowed tip 2, which contains a hinged petals 3 and is rigidly fixed to the petals, plunge into the ground to a predetermined depth, fall asleep protoplasts mixture 5 in the inner cavity of the tube and tapering tip, raise the hollow casing pipe 1 to the level covered a mixture of 5 and thereby provide disclosure of hinged petals 3. Protoplasma mixture 5 is poured into the vacant cavity.

Operation filling protoplasma mixture 5 and lifting the casing 1 is repeated as many times as necessary for the formation of piles.

After removing the casing 1 from the soil provide a folding hinged petals 3 in a narrowed tip 2.

After the first dive into the ground casing 1 with a head 2 and extract perform at least one subsequent immersion so that the cross-sectional area protoplasma mixture obtained after the first dive, overlaps in any way the subsequent dive.

The operation of immersion and extraction of the casing 1 with filling protoplasma mixture 5 is performed in sequential matching is Telenesti, defined design features constructed of a building or structure and characteristics of soils. For example, subsequent immersion comply with eccentricity from the axis of the first dive is less than the lateral dimension of the cross section, for example less than the diameter of the cross section, this dive. It is advisable the subsequent dive to do with the formation of the pile cluster ABC (see figure 3) from protoplasma mixture of 5 by immersing the casing 1 in the center of the Bush for the formation of the Central piles D. Axis dives casing with the tip can be positioned at equal distance from each other and at a distance equal to their radius from the center of the Bush ABCD (see figure 3). Perhaps the subsequent immersion of the casing with the tip to perform in the same location as the first dive.

Through supply of tapering tip 2, at least one blade fixed on the hollow casing pipe, increases the strength of the tip and its petals. This is because when submerged casing pipe with tip load from the ground is transmitted through the fixed petals directly on the casing 1, while having smaller strength of the hinges 4 are discharged, which increases the strength of the tip.

All this allows to compact the soil with a stronger seams, and re-seal previously upl is tennage soil.
