Description

The invention relates to the construction and can be used for the construction of coastal protection, slope reinforcing, retaining, as well as to protect the banks of water bodies from wave effects.

In recent years, in the Russian Federation and in a number of other foreign countries, mainly protective structures from reinforced concrete blocks with a broken profile and an inclined front face with through confuser holes have been mainly used.

The disadvantages of the structures of these elements is that they cannot be used for deep water bodies, since they do not have sufficient operational reliability due to the low bearing capacity for bending and shear, and are ineffective for strengthening high slopes.

The closest in technical essence to the achieved result is a reinforcing element that holds and strengthens the structure and contains soil or stones (patent RU No. 2194823 C2, IPC E02D 29/02, 17/20, published on January 20, 2008).

The element holding and strengthening the structure, containing a continuous section of wire mesh with a lower part, an intermediate, front holding part and an upper end covering part, the parts are separated from each other by reinforcing bars that define predetermined bending lines of these parts relative to each other, while forming a holding a channel-shaped element, the element contains a support bracket that is connected to the intermediate part, supporting and positioning the intermediate part in a vertical or on lonnom position relative to the bottom.

The disadvantage of this element is that the transportation of prefabricated elements to the work site is quite expensive, and their assembly is complicated.

The objective of the present invention is:

- increasing the stability of the structure to dynamic loads during complex

natural processes, including in earthquake-prone areas;

- simplification of the assembly process of the structure at the facility by reducing the number

metal modular elements and bolted threaded connections;

- absorption by gabion structures in conditions of instability of soils,

possible rainfall without destroying the structure itself.

- improving the efficiency, versatility and reliability of the structure.

It:

- low operating costs;

- simplicity of design that does not require skilled labor;

- elimination of additional costs for the installation of drainage systems, as

gabions are permeable structures;

- environmental friendliness - they merge with the environment and represent

Natural building blocks of the landscape.

The solution to this problem is achieved in that the gabion of high strength holding structures, contains a continuous section of wire mesh, including at least the lower part, the intermediate, front holding and upper covering, according to the invention, the rectangular section consists of galvanized metal galvanized multi-coil rings diameter from 200 to 290 mm, with a breaking load of the ring - not less than 12 tons, interconnected horizontally and vertically, forming a rigid box with subsequent filling It can be treated with stone material, in addition, a mesh or membrane of galvanized knitting wire with a diameter of not more than 40 mm, small cells measuring no more than 40 × 100 mm adjacent to the chain mesh is installed in the section, the membrane walls are connected by a connecting wire, to increase stability and impart a section a rectangular wooden formwork is used, the walls of which are connected by metal ties, bolts, which allows to increase, if necessary, their height, to enhance the bearing capacity of the section about its base is attached to the ground with anchors with a diameter of at least 14 mm to a depth of at least 1200 mm.

This utility model has a simple design, involves a significant reduction in costs, avoids difficulties in placement, and in comparison with traditional designs provides a technical result, expressed in stability, efficiency, economy of the proposed section of the structure, its optimal ratio of weight and bearing capacity, reducing time construction, simplicity and speed of installation, less complexity in the assembly section, a sufficiently high durability, compliance with the requirements environmental protection.

Despite the relatively high unit cost of the metal chain mail mesh made of multi-turn rings of high strength and the adjacent mesh of galvanized wire with smaller cells, which allows the use of local soil, the proposed section is much more efficient in operation and economical in construction compared to traditional massive structures .

The invention is illustrated by the attached drawings, in which:

Figure 1 - gabion from the rings of chain mail and metal mesh;

Figure 2 - installation in the section of chain mail and wire mesh;

In Fig.2 - a wooden formwork of a rectangular shape;

In Fig.4 - metal ties with bolts for stiffening wooden formwork;

Figure 5 - laying layer by layer of stone and screed walls of the duct galvanized wire.

High strength gabions 1 include: a continuous section made of metal chain mail mesh 2, collapsible timbering 3, the walls of which are connected by metal ties 4, bolts 5, a galvanized wire mesh 6 is laid along the walls of the section along the perimeter of the chain mail mesh along the section walls, the base of the box 7 , the box is filled with stone material 8, a wire 9 connecting the mesh links around the perimeter, the leveling layer 10, stones 11.

To enhance the bearing capacity and stability of the gabion, the walls of the section are rectangular, the stone material is laid in layers, the overlying layer presses on the bottom, enhances the section's shear and tipping stability.

Such a structure can be effectively used as shore protection in eroded channels while protecting river banks and canals from erosion.

High strength gabions 1 contain a continuous section of metal chain mail mesh 2, consisting of multi-turn rings, hot-dip galvanized with a zinc layer with a thickness of at least 80 μm, a diameter of 250 to 500 mm with a breaking load of one ring of at least 12 tons. The rings are connected between horizontally and vertically, forming a box with a size of at least (2 × 1 × 1 or 2 × 1 × 0.5).

From the inside, along the perimeter along the walls of the box of chain-mail mesh, a metal mesh of galvanized wire with a thickness of at least 4 mm with a breaking load of at least 3,500 to 5,000 kg is laid, which helps withstand any type of load.

A box of metal chain mail mesh and galvanized wire mesh is filled with stone material.

The construction of a high-strength gabion (see Fig. 1) is carried out as follows: the construction site is carefully inspected and prepared, the vegetation layer is removed and a leveling layer 10 with a thickness of 150-200 mm is poured from any drainage soil (see Fig. 4).

On the prepared base, the mail chain 2 panels are laid and fastened to the ground with anchors with a diameter of at least 14 mm, to a depth of at least 1200 mm.

To give the section a rectangular shape, a collapsible wooden formwork 3 is used, the walls of which are installed along the cloths of the base of the chain mail mesh and are fastened with ties 4, bolts 5. Inside the formed box, the cloths of chain mail 2 are stretched (Fig. 2), metal is laid around the perimeter adjacent to the chain mail galvanized wire mesh 6. Mesh 2 and 6 are interconnected by a connecting wire. Stones 11 are stacked in layers on a chain-mail mesh base.

To ensure maximum stability of the gabion at the facility, after laying the layer of stones to a height of 500 mm, the gabion walls are connected by wire 9 (Fig. 5), then the second layer is laid and is so consistently filled to the required height.

Depending on the functional purpose of the gabion, large stones 11 are laid along the perimeter of the box (Fig. 1), and the middle is filled with any soil available on site and meeting the requirements of the structure for strength and frost resistance.

After filling with rocky material, the gabion can be closed with a lid.

Then metal ties with bolts are removed and the formwork is disassembled and high-strength gabion remains with a volume of at least 2 m ³ , then metal ties and wooden formwork elements are used to assemble the next section.
