Description

The utility model relates to the construction of the foundations of soil platforms, and can be used in the construction of roads, the strengthening of the coastal strip and various slopes, during the construction of dams in wetlands, as well as in the construction of trunk pipelines, airfields, site facilities, etc.

Known geomatrix containing ribbons, at least some of which are made of synthetic polymeric material with filtering ability, moreover, the ribbons are interconnected to form their planes in the plan of rectangular cells and have loops or cords for temporary fastening to the device for tensioning the ribbons in the moment of filling the cells made in the form of beams and rods, see RU 78233.

However, in the manufacture of the known geomatrix, loops or cords for temporary fastening to the device for tensioning the tapes at the time of filling the cells are fixed on the tapes after the formation of the cells, i.e. for their attachment, an additional technological operation is necessary. In this case, the loops are attached on the sides of the cells, which, when filling the cells with soil, leads to the folding of the cells and thus get a poor-quality base. In this case, the loops can break, which leads to the same consequences as indicated above.

This problem is solved in the aggregate by the proposed geobox and device for tensioning the tapes at the time of filling the cells for the specified geobox.

The technical result is the creation of a geobox and a device for its laying, which ensure, with the simplicity of their design, the guaranteed filling of the cells with soil and its retention during operation, as well as the prevention of its washing out under various hydrogeological operating conditions.

The specified result is achieved by the fact that:

the geobox contains tapes, at least some of which are made of synthetic polymeric material with filtering ability, and the tapes are interconnected to form planes in the plan of rectangular cells and have loops or cords for temporary fastening to the device for tensioning the tapes at the time of filling cells. The ribbons in the cells are connected by a sewing seam, and the loops or cords are sewn to at least one vertex of the cell, and the ribbons are made of at least two layers.

The device for tensioning the geobox tapes is made in the form of beams connected with the formation of a rectangle in terms of beams and rods mounted on the beams in parallel with each other for connection with the cells. The rods are parallel to one of the diagonals of a rectangle formed by beams.

The location of the loops in the corners of the cells makes it possible to stitch the ribbons with the formation of cells while sewing the loop. Multilayer provides increased strength, both for holding the loop, and guaranteed filling of the cells with soil and its retention during operation, as well as preventing its washing out in various hydrogeological operating conditions.

The possibility of arranging loops at the corners of the cells is provided by the original design of the device for tensioning the geobox tapes, namely, by arranging the rods parallel to one of the diagonals of the rectangle formed by the beams, i.e. rods go through the tops of the cells.

The geobox is made of modern composite materials - a two-layer (or 3-layer) geocomposite, consisting of a grid and (or) geo-fabrics, providing load distribution in the structure and giving it filtration capabilities. The material has high tensile strength, resistance to structural damage and environmental influences.

In the production of geoboxes, the highly effective TexStab geocomposite material is used, which provides structures with increased strength, durability and good filtration properties.

Modification of geoboxes with a bottom sewn in the factory significantly simplifies the installation process and then earthwork, increases the operational reliability of the structure (there is no extrusion of soil through the cells down) and provides additional rigidity of the soil layer.

The use of waterproofing materials ("GSW" or "GW") in the manufacture of TexStab M geoboxes provides protection of the structure from groundwater penetration. Geoboxes with a waterproofing bottom are produced (to ensure the protection of overlying soils from water saturation due to groundwater and in wetlands), as well as geoboxes with waterproofing walls and a bottom (to protect against penetration of water into the soil mass both from below and due to lateral water inflow).
