Description

one

The invention relates to the construction, in particular to spreading anchors, and can be used to temporarily fix various mounting devices into the ground.

A soil anchor is known, which is a precast reinforced concrete structure consisting of an expansion wedge and several short prismatic pile-arms.

However, the use of such an anchor is uneconomical, since it requires additional equipment for the formation of the leader well and the crushing of pile-cantilevers. In addition, the range of use of the known anchor is low, it cannot be used to fasten structures on areas ct with weak soils where operation of human techniques is impossible.

Most; Close to the present invention is an anchor for soft soils, including cantilevers that open when embedded in the soil 2.

However, the use of this anchor is complicated because of the need for a busy installation of additional equipment.

The purpose of the invention is to simplify the production of work when erecting an anchor.

The goal is achieved by the fact that in an anchor for soft soils, including console, the latter are curved, facing each other with convex surfaces and provided with curved surfaces mounted on them

0 direction, carriage with a block and a winch fixed on the upper end of one of the consoles, and stored in the block cable, with one end of the cable stocked on the winch drum, 5 and the other fixed on the upper end of the other console.

With this, each of the anchor cantilevers is provided with a plate with holes fixed in its upper part.

In addition, the leading ends of the consoles are made with bevels.

FIG. 1 shows an anchor for soft soils, general view; figure 2 is the same in the working position; in FIG. 5. 3 -. view A in FIG. 2, in FIG. 4, section BB in FIG. 1 in FIG. 5 shows a section B-B in FIG. in fig. 6 - section GGD in figure 2.

The anchor includes curved ends of salt 1 of the T-shaped cross section. Curved guides 3 are fixed to the edge 2 of the brand along the convex edge. On the top part of the console of the cantilevers 1 are fixed plates 4 with holes 5, and the lower leading ends of the cantilevers 1 are made with bevels 6. The carriage is mounted with the possibility of shifting the guide 3 7, in block 8 of which a cable 9 is stockpiled, one end of which is fixed on the upper end of one console 1, and the other end is stored on the drum 10 of the winch 11 fixed on the upper end of the second console 1.

The installation and operation of the anchor is carried out as follows.

Consoles 1 are pressed into the ground to a depth sufficient to develop reactive resistance of the soil. A guide carriage 7 with a cable 9 stored on its block 8 is mounted on the guides 3. One end of the cable 9 is fixed on the upper end of one of the cantilevers 1 and the other is fixed on the drum 10 of the winch 11. After that, rotating the drum 10 of the winch 11, nat the cable 9 is turned. 9. The carriage 7 is moved by the tension force of the cable 9 along the guides 3 of the cantilevers 1 upwards, as a result of which the cantilevers 1 are rotated relative to each other around the instantaneous centers of rotation. embedded in the ground.

After the cantilevers 1 are sunk to the design depth, the carriage 7 is removed from the guides 3 of the cantilevers 1, the cable 9 and the winch 11 are disconnected and

the upper ends of the consoles are rigidly connected to each other.

The proposed anchor has a large bearing capacity and is easy to install.
