Description

The technical solution relates to environmental and hydraulic engineering construction, can be used to protect and restore the coastline.

Known cylindrical gabion (patent No. 2418908 RU, IPC E02B 3/00, published on 05/20/2011 Bull. No. 14), including the outer, intermediate and inner mesh, the inner space between them is filled with stone, the top and bottom of the cylindrical gabion is closed by a plug .

The disadvantage of this solution is the low adaptability of the device.

As a prototype, a protective system was selected (patent No. 2529741 RU. IPC E02B 3/04, publ. 09/27/2014, Bull. No. 20), including gabion, having opposite side walls, connected to each other at certain intervals along the length of the gabion by several dividing walls, while the gaps between adjacent pairs of dividing walls limit together with the side walls at least one separate gabion compartment, and at least one separate gabion compartment is bounded by corresponding opposite side walls or vopolozhnymi wall portions in respective opposite side walls, the partition walls are pivotally connected to the side walls, and a separate compartment of the gabion extends outwardly therefrom with an at least partially converging open frame panels forming all or part protruding forward compartment of the gabion. One separate compartment is at least partially filled with filling material, one forward protruding compartment has a mesh shape.

The disadvantage of this solution is the complexity of manufacturing and installation along the coastline.

The technical task of the claimed device is to expand the functionality of the gabion.

The essence of the technical solution is. that the cylindrical gabion, including grids and filling material located in one compartment, while the gabion is made in the form of two cylindrical grids installed concentrically with respect to the axis of symmetry, the filling material is located between the outer and inner gabion grids, the cylindrical grids are made of fiberglass reinforcement, and in hollows of the internal mesh are placed collectors for growing mussels.

Common features with the prototype are:

the presence of the grid,

filling material located in gabion.

Distinctive features of the claimed device are:

two cylindrical mesh.

the grids are mounted concentrically with respect to the axis of symmetry.

the filling material is located between the outer and inner gabion net.

cylindrical mesh made of fiberglass reinforcement,

collectors for growing mussels are placed in the cavity of the inner grid.

The combination of essential features ensures the achievement of the declared effect: the expansion of functionality by strengthening the coastline and providing the ability to grow mussels, which does not require additional fastening of the collectors. In addition, the implementation of gabion nets from fiberglass reinforcement provides high corrosion resistance and durability of gabion in sea water.

In FIG. 1 is a longitudinal section through a cylindrical gabion.

In FIG. 2 shows a cylindrical gabion in cross section.

The cylindrical gabion contains (Fig. 1, Fig 2) outer 1 and inner 2 nets made of fiberglass reinforcement and located concentrically relative to the axis of symmetry.

The cavity 3 between the outer 1 and inner 2 nets is filled with filling material 4, for example, with a stone about 0.1-0.3 m in size. At the bottom, the gabion is closed with a plug in the form of a mesh 5. made of fiberglass reinforcement. In the cavity 6 inside the grid 2 are collectors 7 for growing mussels, which are mounted on spacers 8 and are equipped with a load 9. The collectors 7. located in the cavity 6 are made with the possibility of replacement as the mussels grow.

Example.

Cylindrical gabion can be made with a diameter of 3 m, a height of 5 m. The concentric arrangement of the nets is due to the need to form a cylindrical cavity to accommodate the mussel growing collectors, fiberglass reinforcement has the following characteristics: diameter 20 mm according to GOST 31938-2012. The collectors located in the cavity 5 can be made of nylon ropes. Ropes are fixed on jumpers and equipped with weights.

The technical solution provides enhanced functionality by strengthening the coastline and providing the possibility of growing mussels that do not require additional fastening of the collectors. In addition, the implementation of gabion nets from fiberglass reinforcement ensures the durability of the structure due to the high corrosion resistance of fiberglass reinforcement in sea water.
