Description

The invention relates to environmental management of mountain and foothill landscapes and can be used as anchors for anti-erosion and anti-landslide structures, as well as in emergency situations.

A device for anchoring anti-landslide structures is known [1]. A device for anchoring anti-landslide structures includes laying an overlapping woven mesh by unwinding the rolls with the long side across the direction of movement of the slope and securing them to the slope with anchors with tips. The wire anchor has a rotating thrust element, which in working condition assumes a perpendicular position relative to the wire attached to the landslide protection structure. The lower end of the thrust element has a conical shape, and the upper end is flat, truncated at an acute angle relative to the axis of symmetry.

The disadvantage of this technical solution is:

low reliability during operation;

low load-bearing capacity.

The closest tonic solution is a wire anchor with a conical tip [2]. A wire anchor with a tapered tip involves laying overlapping woven mesh by unwinding the rolls with the long side across the direction of travel when working; with fastening on the slope with anchors with tips. The wire anchor has a conical tip with a guide rod, which in its working position takes the direction coinciding with the wire, which is attached to the landslide protection structure.

The disadvantage of this technical solution is:

low load-bearing capacity;

low efficiency at work;

low load-bearing capacity to bear lateral loads.

The purpose of the invention is to increase load-bearing capacity and operational efficiency.

This goal is achieved by the fact that along the height of the wire above the conical tip, rods are rigidly fixed around the circumference, which, when the guide rod is removed from the ground, open to form anchor umbrellas. To enhance the process of opening the rods by the operator, the guide rod can be used to improve this process by lowering it down. The thickness of the wire in height in the direction from the conical tip to the ground surface increases and is in the range of 5÷20 cm. This makes the load on the wire uniform, since the force on the anchor increases in height. The distance between the anchor umbrellas in height in the direction from the conical tip to the soil surface varies and is in the range of 30÷70 cm. The distance depends on the type of soil and its physical and mechanical characteristics. The length of the rods varies and can be 10÷40 cm. The number of rods can be from 3 to 8 with an installation angle between them where n is the number of rods.

The longer the rods, the larger the diameter of the anchor umbrella. The diameter of the base of the conical tip is 1÷3 cm larger than the diameter of the outer guide rod. This allows you to reduce the friction force when driving the guide rod into the ground. The driving depth of wire anchors reaches 15÷20 m. Concrete or other composite material can be used as a material for the manufacture of a conical tip. The material for making rods and wires can be metal or a composite material.

The invention is illustrated by drawings, where in Fig. Figure 1 shows a cross-section of a wire anchor with a guide rod when installing the device, general view; in fig. Figure 2 shows an installed wire anchor with the guide rod removed, general view.

A wire anchor 2 with a conical tip 3 is installed on the ground 1. Rods 4 are rigidly fixed along the length of the wire anchor 2. The installation of the wire anchor 2 is carried out using a guide rod 5.

The wire anchor is installed and works as follows. Along the height of the wire above the conical tip 3, rods 4 are rigidly fixed around the circumference, which, when the guide rod 5 is removed from the ground 1, opens to form anchor umbrellas (Fig. 1). To enhance the process of opening the rods 3 by the operator, the guide rod 5 can be used to improve this process by lowering it down. The thickness of the wire in height in the direction from the conical tip 3 to the surface of the soil 1 increases and is in the range of 5÷20 cm. This makes the load on the wire uniform, since the force on the wire anchor 2 increases in height. The height distance between the anchor umbrellas in the direction from the conical tip 3 to the soil surface 1 varies and is in the range of 30÷70 cm. The distance depends on the type of soil 1 and its physical and mechanical characteristics. The length of the rods 4 varies and can be 10÷40 cm. The number of rods 4 can be from 3 to 8 with an installation angle between them where n is the number of rods. The longer the rods 4 are, the larger the diameter of the anchor umbrella. The diameter of the base of the conical tip 3 is 1÷3 cm larger than the diameter of the outer guide rod 5. This allows to reduce the friction force when driving the guide rod 5 into the ground. The depth of driving the wire anchors reaches 15÷20 m. As a material for the manufacture of the conical tip 3 Concrete or other composite material can serve. The material for making the rods 4 and the wire of the wire anchor 2 can be metal or a composite material (Fig. 2).

Wire anchors of the proposed design are more effective than known wire anchors with conical and rotary tips in terms of load-bearing capacity, are capable of working with lateral forces, and require low capital investments.
