Description

The utility model relates to the field of construction and can be used to protect industrial sites from flooding, as well as to strengthen the soil embankment over the pipeline by using means to fix and hold the surface layer of the embankment mainly on a frozen base.

The GEOWEB type geogrid is widely known for reinforcing slopes, made in the form of ribbons made of polymer material connected to each other in a checkerboard pattern with a given step, fixed on the slope in a position stretched to form diamond-shaped cells (RU No. 2152479, C1, E02D 17 / 20, 2000).

Also known is a geogrid formed by strips of polymer material located on a polymer base with the formation of cells filled with granular material with partially bent walls against the direction of the slope (SN No. 652155, A5, E02D 17/20, 1985). The closest known device is to strengthen the soil embankment over the pipeline, mainly on a frozen base, containing geogrids fixed to the embankment and fixed by anchors, the cells of which are formed by interconnected, preferably perforated tapes, at least some of the cells contain filling material, preferably granular while the lower edge of the geogrid located on the slopes adjoins its section, preferably located in the horizontal plane of the cat cell swarm filled and / or torfopeschannoy mixture and / or sand and / or gravel, preferably, fraction 20-40 mm, and in flooding zone - with gravel and / or concrete (RF №42835 patent E02D 17/20, 2004).

Known designs of devices for strengthening soil slopes

structures do not fully solve the problem of securing the material on the slope due to the possible displacement of the geogrid down the slope under the influence of the filling material both during placement of the material in its cells and during operation of the cells filled with filler due to the use of bulk material such as peat sand, crushed stone and others with insufficient specific pressure. And, as a result, there is a loss of a given slope profile and the formation at its base of an accumulation of material poured into the cells.

The objective of this proposal is to protect industrial sites from severe flooding, significant stormwater and spring floods by increasing the bearing capacity of the coating, especially in permafrost, which excludes extrusion of the drainage channel base, as well as increasing the durability and stability of the coating profile.

This is achieved by the fact that the device for protecting industrial sites from flooding, stormwater and spring floods, made in the form of a drainage channel, the surface of which is covered with a substrate, on top of which there is a geogrid, the diamond-shaped cells of which are formed by stretching and connected to each other with an equal step with polymer tapes, through the drainage openings of which polymer or metal cables are placed in rows in rows, fixed at the edges of the geogrid and using Erov attached to the base filler material placed in the cells geogrid. In this case, the substrate is made of a non-woven synthetic material or geogrid with the possibility of providing drainage, reinforcement and even distribution of loads over the area, the cables attached to the geogrid using anchors are attached to the slopes and adjacent slopes, as

concrete was used to fill the material, on top of which a load was placed in the form of a monolithic stone or blocks of artificial or natural origin, pressing the geogrid to the base and absorbing the destructive energy of the medium flow generated by storm water or spring flood.

There are other possible embodiments of the utility model, according to which it is necessary that:

- the substrate is multilayer in the form of interconnected layers of geotextiles;

Figure 1 shows a cross section of an industrial site, in particular embankments over a pipeline reinforced with a geogrid,

Figure 2 is a top view of figure 1.

Figure 3 is a fragment of a geogrid filled with cement.

A device for protecting an industrial site from flooding, storm water and spring floods is used in the field of construction of various structures, in particular during the repair and reconstruction of an embankment of pipelines. According to a useful model, the device for protecting the industrial site is made in the form of a drainage channel 1, the surface of which is covered with a substrate 2, on top of which there is a geogrid 3, diamond-shaped cells 4 of which are formed by polymer ribbons mounted on a rib and interconnected with an equal pitch 5. On the side drainage holes 6 are made on the sides of the geogrid, through which polymer or metal cables 7, arranged in rows, are passed into the cells 4, fixed at the edges of the geogrid and using cores 8 are attached to the base 9, in the cells 4 of the geogrid is placed filling material 10.

The substrate 2 is made of a non-woven synthetic material or geogrid with the ability to ensure effective drainage

accumulations of water formed due to flooding, storm water and spring floods, as well as reinforcement and uniform distribution of loads over the area.

Cables 7, mounted on the geogrid, with anchors 8 are attached to the slopes, adjacent slopes and on the base of the channel, while concrete is used as a filling material, cementing the geogrid as if in a single unit, forming flexible mats, on top of which a load is placed on the base in the form of a monolithic stone or blocks 11 of artificial or natural origin, pressing a geogrid with a filler to the base and quenching the destructive energy of the medium flow formed by storm water or spring high water.

In order to evenly distribute the load over the base area, the substrate is multilayer in the form of interconnected layers of geotextiles.

Using the proposed device can increase the durability of the proven geogrids, especially type GEOWEB, reduce current costs for their maintenance.
