Abstract

1. BORING, including the trunk expanding upwards with a central vertical through extension 51101 from the bottom of the cavity, differs from the fact that, in order to either reduce the material intensity and increase the strength of the pile, the barrel is wider with additional vertical cavities spaced apart from each other around the central cavity and separated from it by curvilinear, reversed convex surfaces. to the axis of the trunk by the walls, 2. The sva of claim 1, which is such that the walls separating the additional pollen from the center of the shaft are made of a variable that decreases at the top of the width. e oo o el 00

Description

The invention relates to the construction, namely, to the construction of driven piles of the foundations of buildings and structures. _λ

A pile for permafrost soils is known, the trunk of which has an open- ^! the cavity that is thawing from the bottom of the section, tapering upwards [1].

However, such a pile cannot be used in ordinary soils due to the fact that when it is clogged, the air inside the cavity is compressed and prevents the pile from sinking or destroys its walls.

The closest to the invention in terms of technical nature and the achieved result is a pile, including a trunk expanding upward with a central vertical through cavity extending downward [2].

of the central cavity and separated from it by a curved, convex surface facing the axis of the gpyr walls.

In this case, the walls separating up to? filling cavities from the central, can be made variable, decreasing upward of the width.

In FIG. 1 shows a pile, top view} In FIG. 2, - the same., View from below; ' in FIG. 3 - section AA in FIG. 1} in FIG. 4 - pile, general view.

The proposed pile includes upwardly expanding trunk 1 with a central vertical through-cavity extending downwardly from cavity 2 and additional vertical upwardly expanding cavities 3 located at a distance from each other around the central cavity 2 and separated from it by curved walls 4 facing the convex surface to the axis of the pile, which can be 'executed by a variable decreasing upwards of the width due to a change in the slope of the faces 5 between these walls. In the lower part of the trunk may have ledges b.

When driving, the soil inside the central cavity exerts pressure on the walls, moreover, due to their curved convex surface facing the axis of the pile, and also due to the presence of additional cavities, the material consumption of the pile shaft is reduced.

The disadvantage of such a pile is the incomplete use of the strength of continuous walls, leading to an overuse of materials.

The purpose of the invention is to reduce material consumption and increase the strength of piles. |

This goal is achieved by the fact that in the pile, including the expanding upward trunk with a central vertical through cavity extending downwardly, the trunk is made with additional vertical cavities expanding upwardly open from the side of the upper end of the trunk and placed at a distance from each other ³³ and increasing strength

Claims (2)

1. A pile, including a trunk that extends upward with a central vertical through cavity extending downward, south and south; This is due to the fact that, in order to reduce material consumption and increase the strength of piles, the trunk is made with additional vertical cavities expanding upwards open from the side of the upper end of the trunk, spaced apart from each other around the central cavity and separated from it by curvilinear, facing convex surface. to the axis of the barrel walls 2. Pile on π. 1, with the fact that the walls separating the additional cavities from the central are made of a variable decreasing upward in width. 1043050
