Description

The invention relates to the construction and is used in the construction of pile foundations for columns of industrial agricultural and other buildings.

The purpose of the invention is to increase the bearing capacity of the pile.

FIG. 1 shows a pile, longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4-8 are the stages of pile construction.

Sva contains a reinforced concrete shaft 1, a padded shell 2 placed around the shaft and combined with it. The padded casing is made of a multilayer of concrete layers 3 spaced coaxially from each other and interlayers of bulk material 4 arranged between them (for example, soil, sand, or other similar material). Reinforced concrete barrel 1 is installed in the upper part of the inner concrete layer 3 of the shell and is separated from its lower part by a transverse concrete diaphragm 5 and a layer of bulk material 4.

The pile is erected as follows.

At the planned construction site, using a round or square hollow die 6, which is immersed in the soil by vibration, static indentation or driving, form well 7 at a predetermined depth while simultaneously creating a compacted zone 8. After the die is immersed, it is removed and the resulting hole is filled with concrete a mixture of 9 to the full depth. In the case of arranging such piles in flooded soils, a hollow die is used as a casing through which the well is filled with material from the bottom up. After filling up the well, the die is reversed into the well to its original depth. For one

5 or several passes of the stamp 6 in the soil mass form a closed shell of the concrete layer 3 and form a compacted zone 8. To create a ground or sand packed compacted layer, the cavity formed in the concrete with dimensions equal to the size of the stamp is filled with soil, sand or other similar material 10 according to the principle described above, and in one or several punch passes, an interlayer of bulk material 4 is formed, under the influence of which the concrete layer 3 is displaced into the soil mass with its simultaneous compacting, which decreasing wall thickness and increase in the volume of compacted soil. Thus, a padded casing is formed in the soil mass. The casing is made of a multi-layer concrete layers arranged coaxially at a distance from each other and interlayers of bulk material placed between them. The final stage of the pile device consists in filling the bulk material and compacting the interlayer of bulk material 4 (Fig. 1) 1 / 2-2 / 3 of its depth, filling the rest of the concrete mix into which the reinforced concrete shaft is immersed to a predetermined mark. After the concrete has set, a pile is formed

0 increased bearing capacity, which can be assigned differentiated depending on the number of concrete layers and layers of bulk material between them.
