Abstract

FIELD: construction.

SUBSTANCE: gabion retaining wall includes stones, arranged in a grid frame with hexagonal cells. The stones, filling the space of the grid frame, are artificial and previously made of concrete. A glass-cloth with lining along the perimeter is stacked between the layers of stones inside the gabion in a horizontal plane over the entire height. The artificial stones have preferably cubic or prismatic shape and may be packed in columns or with displacement in layers. Such technical solution will prevent the thrust of the gabion retaining wall and will significantly increase the height. Large effect will be achieved if the glass-cloth will be glued to the contacted layers of stones.

EFFECT: increase of the bearing capacity and efficiency.

Description

The invention relates to environmental management and water management and can be used to combat water erosion.

Known gabion retaining wall, including stones and mesh [1]. The disadvantages of this technical solution are:

- the need to use natural stone;

- small bearing capacity and structural strength.

The closest technical solution is a gabion retaining wall, including stones and a grid with hexagonal cells [2]. The disadvantages of this technical solution is:

- the relative complexity of the design of the gabion retaining wall;

- the need to use natural stone, which is not a local building material.

The purpose of the invention is to increase the bearing capacity and economy.

This goal is achieved by the fact that an artificial cubic (figure 3) or prismatic (figure 4) stone is placed in a mesh frame (figure 5) with hexagonal cells. Artificial stones are made in advance in the production environment, delivered to the construction site of gabions and have a predominantly cubic or prismatic shape. Artificial stones filling the space of the frame of the grid 4 can be stacked in columns (figure 2) or with an offset in the layers (figure 1). Moreover, laying in a column is possible for both cubic stones and prismatic stones. When laying with an offset in the layers, a more durable structural solution is achieved. The manufacturing technology of gabion retaining walls is similar to technology with natural stone.

An apron is provided to protect the gabion retaining wall from being washed away by the water stream. The structural solution of the apron is similar to the structural solution of the gabion retaining wall. When calculating the gabion retaining wall, it is necessary to ensure stability against tipping over from the pressure of the embankment. Between the layers of cubic or prismatic stones in the gabion retaining wall, a fiberglass fabric with pasting along the perimeter or over the entire area is laid. Fiberglass between the layers of stones inside the gabion in a horizontal plane is laid over the entire height. The number of layers of stones can vary from 2 to 5 stones. Such a technical solution will prevent the gabion retaining wall from spreading and will significantly increase the height. A greater effect will be achieved if the glass fabric is glued over the entire area to the contacting layers of stones.

To reduce the pressure on the soil, the bases of the gabion retaining wall can be used for the manufacture of cubic and prismatic cubes not only concrete, but also other lightweight material, such as foam concrete, etc.

Figure 1 shows a gabion retaining wall of prismatic stones stacked with offset; figure 2 shows a gabion retaining wall of cubic stones laid in columns; figure 3 - cubic stone, a perspective view; figure 4 - prismatic stone, axonometry; figure 5 - gabion frame of mesh with hexagonal cells, a perspective view; figure 6 - fiberglass, a perspective view.

The gabion retaining wall 1 props the embankment 2 and protects the banks 3 from erosion by the flow of water. The gabion retaining wall 1 consists of a mesh frame 4, into which a cubic 5 or prismatic stone 6 is placed. To protect the base of the retaining stack 1, an apron is provided 7. Fiberglass 8 is laid between the layers of cubic 5 or prismatic stones 6 in the gabion retaining wall 1.

Gabion retaining wall is constructed and operates as follows. An artificial cubic 5 (FIG. 3) or prismatic (FIG. 4) stone 6 is laid in a mesh frame 4 (FIG. 5) with hexagonal cells (FIG. 1). Artificial stones filling the space of the grid frame 4 can be stacked in columns (FIG. .2) or with an offset in the layers (Fig. 1). Moreover, laying in a column is possible both for cubic stones 5 and for prismatic stones 6. When laying with an offset in the layers, a more durable structural solution is achieved.

To protect the gabion retaining wall 1 from being washed away by the flow of water 3, an apron 7 is provided. The design of the apron is similar to the constructive solution of the gabion retaining wall. When calculating the gabion retaining wall 1, it is necessary to ensure stability against overturning from the pressure of the embankment 2. Between the layers of cubic 5 or prismatic 6 stones in the gabion retaining wall 1, fiberglass 8 is laid with gluing around the perimeter or over the entire area. Such a technical solution will prevent the gabion retaining wall from spreading and will significantly increase the height. A greater effect will be achieved if fiberglass 8 is glued to the contact layers of stones.

The proposed technical solution is effectively used in areas where there is no natural stone, and the use of imported stone leads to a strong rise in price of the product.

The gabion retaining wall made of artificial stone has a more aesthetic appearance and greater structural strength compared to the gabion retaining wall made of natural stone.

Such a constructive solution allows the use of lightweight materials as the material for the manufacture of cubic and prismatic artificial stones, which will reduce the weight of the gabion retaining wall and the specific load on the base soil.
