Description

The invention relates to the construction and environmental arrangement of landscapes and can be used as fasteners for poles of power lines, the arrangement of recreation areas on the beaches.

A known method of erecting a suspension cableway support [1], which includes the construction of a foundation of inert material and mounting equipment on a metal conductor frame, the construction of the foundation includes laying and attaching a double weave mesh to the surface of the landscape using brackets, then in the geometric center of the fixed mesh double weave set the conductor frame, made in the form of a vertical double weave mesh, bounded by the lower support and upper mounting plates, connected rigid and stable with the help of rods and bolt joints used as reinforcement, which inside is filled with stones of a given lumpiness, and from the outside, a vault is formed from the same stones, forming the enclosing surface of the foundation, the angle of inclination of the arch to the horizon is steeper than the angle of repose of the laid stones moreover, the metal conductor frame is attached to the double weave mesh on the landscape surface using brackets with its lower supporting part, and metal structures are mounted on the upper mounting plate w support, whose longitudinal axis is drawn through the center of mass of the cross section mounted structure is perpendicular to the tangent at the point of maximum curvature of the wire rope when they bend around the roller battery mounted on the fastening support.

The disadvantages of this technical solution are:

- the design is quite complicated, the road and bulky due to the use of a large amount of technogenic material.

The closest technical solution is a longitudinal through shore protection structure [2], which consists of trunks, fortified from below in gabions, consisting of a net and stones. Gabions are made in the form of cylindrical gabions, buried below the erosion depth, in which the trunks are vertically installed in one or more lines at a certain distance from each other along the direction of the river flow. Vertical trunks are trees or reinforced concrete pillars fixed with stones in cylindrical gabions. The disadvantages of this technical solution are:

- the design and method of anchoring is quite complicated and expensive;

- low efficiency and reliability of the anchors due to the complexity of the design.

The aim of the invention is to increase the efficiency of fixing the pillars and the reliability of their work.

The goal is achieved by the fact that a pit of a rectangular shape comes off at the site, at the bottom of which anchors are hammered in the corners (Fig. 1, 2). The slopes of the pit in cohesive soils can be vertical, and loose soils can be gentle. The driving of wire anchors to the required depth is carried out using the guide rod, which is removed after driving, and the wire anchor remains in the ground. A lining is laid at the bottom of the pit, and the pit is filled with gravel aggregate. At the top of the backfill, a base with a shoe is laid. A pole is installed in the shoe, which is fixed in it (Fig. 3). The wire anchor has a conical tip. The threaded ends of the wire anchor are pulled through a hole in the base and tightened with nuts (Fig. 4). The depth of driving wire anchors into the ground depends on the amount of force required. determined from the conditions for ensuring the necessary stability of the column. The lining at the bottom of the pit is an asbestos slab 10–15 mm thick or a concrete layer 10–15 cm thick.

In FIG. 1 shows a cross section of a pit in a cohesive soil with an installed column, general view; in FIG. 2 - cross-section of the pit in loose soil with an installed column, general view; in FIG. 3 is a section bb, in FIG. one; in FIG. 4 - node A, in FIG. one.

A pit-shaped pit 1 is opened on the site, at the bottom of which wire anchors 2 are clogged at the corners. A lining 3 is laid at the bottom of the pit 1, and the pit is filled with gravel aggregate 4. A base 5 with shoe 6 is laid on top of the backfill. Column 7 is installed in shoe 6. which is fixed in it. Wire anchor 2 has a conical tip 8. The threaded ends 9 of the wire anchor 2 are pulled through the hole in the base 5 and tightened with nuts 10.

The installation method of the pillars is as follows. A foundation pit 1 with a rectangular base comes off at the site, at the bottom of which anchors 2 are hammered in the corners (Fig. 1, 2). The driving of the wire anchors 2 to the required depth is carried out using the guide rod, which is removed after driving, and the wire anchor 2 remains in the ground. At the bottom of the pit 1, a lining 3 is laid, and the pit is filled up with gravel aggregate 4. At the top of the backfill, the base 5 with the shoe 6 is laid. A pole 7 is installed in the shoe 6, which is fixed in it (Fig. 3). Wire anchor 2 has a conical tip 8. The threaded ends 9 of the wire anchor 2 are pulled through the hole in the base 5 and tightened with nuts 10 (Fig. 4). The depth of driving wire anchors 2 into the ground depends on the amount of required force, determined from the conditions for ensuring the necessary stability of column 7. Lining 3 at the bottom of the pit is an asbestos slab 10-15 mm thick or a concrete layer 10-15 cm thick.

The proposed method of installing poles can significantly increase the installation speed and reduce the cost of work to a minimum.

The proposed method is effectively used in recreation areas on sea beaches, since it is supposed to use technogenic material to a minimum.
