The invention relates to construction and can be used in the construction of pile foundations for various buildings and structures.

A pile foundation is known, including hollow round piles, in the cavity of which the columns of the building framework are embedded when the foundation for each column is immersed in a single tubular pile, the upper cavity of which is used as a container for installation of column l.

The disadvantage of such foundations is the impossibility of embedding large piles of columns in the cavity without developing a grillage in terms of the plate, as well as low bearing capacity under the action of vertical and horizontal loads.

The closest to the invention according to the technical essence and the achieved result is a pile foundation, including a bush of hollow piles, united by monolithic reinforced concrete growth by test, 2.

The disadvantage of the known foundation is the high consumption of materials in the manufacture of the powerful plate of the grillage, the greater labor intensity in the production of works and the insufficient bearing capacity over the ground.

The purpose of the invention is to increase the carrying capacity, reduce material consumption and labor intensity in the production of works.

This goal is achieved by the fact that in the pile foundation, which includes a bush of hollow piles united by a monolithic reinforced concrete grillage, on the sides of the piles facing each other, cuts are made in the upper part, and the grillage is placed between the piles in the cut-outs zone.

FIG. 1 shows the floor of the pile with a cutout; in fig. 2 shows a piling scheme with a notch; in fig. 3 - described foundation, section; in fig. 4 is a section A-A in FIG. 3

The foundation includes hollow piles 1 with b1 cut 2 in the upper part. In the cavity of the pile 1, a grillage 3 with concrete 5 plugs 4, with reinforcing mesh 5, welded to the mortgage parts m 6 floor piles i, and glass 7, in which the column 8 is monolithic, is welded.

The pile foundation is carried out as follows.

A hollow pile 1 with a cutout 2 in the upper part is immersed in the ground with the help of a special head cover 9, which closes its cavity to a height of the grillage 15 3 and concrete plug 4. Then the next pile is immersed close to the previously clogged one with cutouts facing each other, or displaced by the size of the head cover 9, sufficient for embedding a column of 20 to 8. After this, an armature grid 5 is installed, attached to the mortgage parts 6 m 1 of the pile 1 by welding, and concrete blocks 4, which rest on the ground plugs 10, simultaneously with a stove grillage 3 in the limits of the cut-outs of 2 piles, forming a cup 7. Then, installation of columns 8 is carried out with concrete grouting it in glass 7 of the grillage 3., 30

Concrete plugs 4 are made, if necessary, at such a height that, under the action of a bending momeit, they can take out pulling forces. headband 9.

When using the described foundation, an increase in the load bearing capacity of the pile is achieved: the foundation by putting the grillage into operation while reducing the material and labor-intensiveness of making the foundation by eliminating the ground, formwork and concrete works on the grillage of significant dimensions and reducing the basic materials of hollow piles with cutouts .
