Abstract

Field of use: fixing in a soil mass of various structures. SUMMARY OF THE INVENTION: Anchor elements are immersed in the ground. In the process of immersion, the anchor elements cut out the entire soil. The anchor elements are immersed until their lower ends are brought together. 5 ill.

Description

The invention relates to the field of construction and relates to a method for erecting an anchor anchor in a soil mass for securing various structures.

The purpose of the invention is to increase the strength of the anchor.

In FIG. 1 shows a soil anchor implementing the method / longitudinal section; ha FIG. 2 is a section AA in FIG. 1; in FIG. 3 is a section 6-B in FIG. 1; in FIG. 4 is a view B a of FIG. 1; in FIG. 5 - node I in FIG. 1.: Soil anchor includes housing and anchor elements. The body is made of two Parallel plates 1. United by a small pen 2, which is located along the axis of the housing and in the upper part is made of a two-stage, box-shaped section. The lobes 1 at the bottom are broadened. Grooves 3 are made along the contour of the plates, curved in the lower and upper parts and rectilinear in the middle. Anchor elements made in the form of elastic tapes 4. are inserted into the grooves of the plates with the possibility of their movement. The leading end of the elastic tapes is beveled. The movement of the tapes is carried out by a pull-out mechanism consisting of a rectangular threaded nut 5 and the screw rod 6 interacting with it through the thread. The screw nut 5 is rigidly connected to the upper ends of the elastic bands by means of rivets.

The method was carried out as follows.

The soil anchor, including the casing and anchor elements in the form of elastic tapes, is parallel mounted along the axis of the casing with the possibility of longitudinal movement along curved paths with the approach of their leading beveled ends, immersed in the ground and crushed into the given point of the soil mass. When the soil anchor is immersed, the anchor elements are longitudinally moved along the axis of the casing along curved paths until their lower beveled ends come closer and touch each other

another with the cutting out of the rear pillar of the soil and its conclusion into the cavity formed by the extended anchor elements when their lower ends come closer,

Then, the housing exerts a pulling force through the rod. The method allows to increase the bearing capacity of the soil anchor by using the weight of the soil cut from the solid pillar and its bearing capacity under the upper end of the flexible anchor elements, which can be significantly increased in soft soils.

SUMMARY OF THE INVENTION A method of erecting a soil anchor by immersing anchor elements in the soil, characterized in that, in order to increase the bearing capacity of the anchor, when the anchor elements are immersed, their lower ends are brought together until they touch each other, while the anchor elements are cut out of the soil and concluded it into the cavity formed by anchor elements when their lower ends come together.
