Description

The invention relates to environmental and hydraulic engineering construction and can be used to protect slopes, ravines, riverbanks and other structures from erosion, during emergency recovery work.

A known method of erecting a gabion mount in flowing water [1], including laying along the banks of the channel on the base of a prismatic form filled with stone gabions. The disadvantages of this technical solution are:

- such a technical solution is inefficient to use when conducting emergency recovery work;

- rigidity and bearing capacity on the action of bending loads of the gabion structure are insufficient.

The closest technical solution is cylindrical gabions [2], including a wicker or other mesh filled with stone. The disadvantages of this technical solution are:

- has a small bearing capacity on the action of bending loads;

- with large sizes, gabions lose their shape, which affects the quality and strength of the gabion cylinders;

- This technology is not allowed to make thick structures.

The purpose of the invention is to increase the rigidity and load-bearing capacity of the cylindrical gabion structure.

This goal is achieved by the fact that hollow cylinders are made from braided or hexagonal mesh with double torsion in the nodes. Thus, an outer cylinder is made of an external mesh. An intermediate cylinder is made from an intermediate mesh, and an inner cylinder is made from an internal mesh. The manufactured cylinders are inserted into each other concentrically relative to the axis of symmetry (Fig.1, 2). The thickness of the wire from which the outer mesh is made is greater than that of the intermediate mesh. The thickness of the intermediate mesh is greater than that of the inner mesh. The inner space formed between the outer mesh, the intermediate mesh and the inner mesh is densely filled with stone (Figs. 3, 4). After filling the cylindrical gabion with stone, the ends are buried with plugs. Thus, when working in tension or bending, tensile stresses perceive all cylindrical gabion nets, and this increases the bearing capacity of the structure. The greatest force from the action of external bending moments falls on the external mesh cylinder, so the mesh is made of wire of greater thickness (figure 5). The smallest bending moment falls on the inner mesh cylinder, so the thickness of the wire is the smallest. The installation of concentrically cylinders significantly enhances both the bearing capacity of the cylindrical gabion and the action of transverse forces. Cylindrical gabion have a length and diameter of 1.0 ÷ 2.0 and 0.5 ÷ 1.5 m, respectively.

Figure 1 shows a cylindrical gabion with two concentric cylindrical nets, General view; figure 3 is a cross section of a cylindrical gabion with two concentric cylindrical nets; figure 2 - cylindrical gabion with three concentric cylindrical grids, General view; 4 is a cross section of a cylindrical gabion with three concentric cylindrical grids; 5 is a cylindrical gabion on two supports.

The cylindrical gabion 1 consists of an outer mesh 2, an intermediate mesh 3 and an inner mesh 4. The inner space between them is filled with stone 5. The top and bottom of the cylindrical gabion 1 is closed by a plug 6.

Cylindrical gabion is made and works as follows.

Hollow cylinders are made from braided or hexagonal mesh with double torsion in the nodes. So from the outer mesh 2 is made of the outer cylinder. An intermediate cylinder is made from an intermediate mesh 3, and an inner cylinder is made from an inner mesh 4. The manufactured cylinders are inserted into each other concentrically relative to the axis of symmetry (Fig.1, 2). The thickness of the wire from which the outer mesh 2 is made is greater than that of the intermediate mesh 3. The thickness of the intermediate mesh 3 is greater than that of the inner mesh 4. The inner space formed between the outer mesh 2, the intermediate mesh 3 and the inner mesh 4 is filled with stone 5 After filling the cylindrical gabion 1 with stone 5, the ends are buried with plugs 6. Thus, when working in tension or bending, tensile stresses perceive all the grids of the cylindrical gabion 1, and this increases the structural bearing capacity ktsii. Cylindrical gabion 1 have a length and diameter of 1.0 ÷ 2.0 and 0.5 ÷ 1.5 m, respectively.

The proposed design of a cylindrical gabion has a highly aesthetic appearance due to the fact that all cylinders have exactly the same dimensions. The quality of the cylindrical gabion, and therefore the bearing capacity for the action of bending loads, is much higher than that of the analogue.

Cylindrical gabions are environmentally friendly technical solutions, and the durability of these structures is 1.5-2 times more than analogues.

Claims (1)

Cylindrical gabion, including mesh and stones, characterized in that the cylindrical gabion has two or more cylindrical grids installed concentrically relative to the axis of symmetry, the inner space is filled with stone, and the thickness of the wire from which the outer mesh is made is larger than that of the intermediate mesh, the thickness of the intermediate the mesh is larger than that of the inner mesh, and therefore the tensile strength of the mesh from the periphery to the center decreases.
