Abstract

SUMMARY OF THE INVENTION: in a pile including a barrel with a broadening in the upper part and a one-sided socket for a supporting element, broadening is performed by a limited part of the side surface of at least one cylinder, the forming of which is located at an angle to the vertical equal to 10-15 °, the upper base of the broadening is located horizontally at the level of the soil surface, and the lower one is no less than at the level of the boundary of seasonal freezing and thawing of the soil, at a downward angle to the surface of the trunk and has a diameter larger than the diameter upper base and equal to 0.5-1.0 bore diameter. A piling may be provided with at least one additional broadening located asymmetrically or symmetrically to the main broadening. The broadening can be located at two levels. 3 s.p. f-ly, 9 ill.

Description

The invention relates to piles, in particular to bored piles, and can be used in the construction of spacer structures on them.

The aim of the invention is to reduce the material consumption while increasing the operational efficiency on the effect of horizontal loads and frost heaving forces.

Figure 1 shows the described pile, side view; figure 2 is the same, with additional broadening; Fig. 3 is the same, with broadening in two levels; figure 4 is a section aa in figure 1; figure 5 is a section bB in figure 2; Fig.6 is a section bb In Fig.Z; Figures 7-9 show variations of the location of the enlargements;

The pile includes a barrel 1 with a broadening 2 in the upper part and a one-sided socket 3 under the supporting element 4 of the spacer structure. The broadening 2 is made by a limited part of the side surface 5 of at least one cylinder, the forming 6 of which is located at an angle to the vertical equal to 10-15 °, while the upper base 7 of the broadening 2 is located horizontally at the level of the soil surface, and the lower base 8 is not less than at the level of the boundary of seasonal freezing and thawing of the soil, at a downward angle to the surface 9 of the trunk and has a diameter larger than the diameter of the upper base 7 and equal to 0.5-1.0 diameter of the trunk 1. At the same time, broadening 2 can be performed by a limited part Mi side surface 5 ras00

laid in plan with equal cylinder spacing. The flange may be provided with at least one additional broadening 10 located asymmetrically or symmetrically to the main broadening 2. The broadening 2 and 11 may be located at two levels.

Piles are made as follows.

A vertical well (not shown in the drawings) is drilled beneath the barrel 1, then additional wells (not shown) are symmetrically or asymmetrically drilled through the same wellhead, and the axes of future extensions 10, 11 are oriented at an angle of 10-15 ° to the vertical axis trunk 1. Then, metal reinforcing cages (not shown) are placed in the wells, the upper parts of which form the reinforcing cage of the pile head. The formwork (not shown) is installed and the pile is concreted with deep vibrating while forming socket 3. After the completion of concrete work, the support element 4 of the spacer structure is installed in the one-sided socket 3 of the piles and connected to the pile.
