Description

The technical solution relates to the field of construction and is intended to strengthen weak foundations for road structures and other structures.

Known three-dimensional geocell containing ribbons made of synthetic polymeric material with filtering ability, which are interconnected by fastening seams, equally strong material of the ribbons, with the formation of their planes in the plan cells of a rectangular shape and have loops or cords for temporary fastening to a device for tensioning tapes at the time of filling the cells, as a synthetic polymer material contains a polyester fabric impregnated with an antiseptic, with the formation in the plan of the cells of a square fo we, and tapes made with bending the upper part and form a cavity for free movement of the rope of synthetic material strength commensurate with the strength tape material; one end of which is equipped with a locking element in the form of a hook or carbine or hook mechanism for interacting with its corresponding mount on the device for tensioning the belts, and the second end of the cable is designed for refueling in the tension mechanism and is additionally equipped with a bottom fastened with the belts forming it and having an inlet for connecting to an adjacent geocell (RU No. 124697 U1, 02/10/2013).

The closest known is a geomatrix containing ribbons, at least some of which are made of synthetic polymeric material with filtering ability, and the ribbons are interconnected to form planes linearly or sequentially along the length or width of the geomatrix of the rectangular or quasi-rectangular cells forms, and the geomatrix is equipped with a cloth discretely or continuously attached to the tapes or discretely or continuously attached to at least partly bandpass segments of the webs forming the bottom of a synthetic resin material having a filtering capability, coupled with at least a portion of the webs to form an open-topped and divided into said flexible duct cell (RU №78233 U1, 20.11.2008).

Known designs do not provide the required reliability and durability, due to the possibility of damage to the outer walls of the soil-filled cells in the process of soil compaction, because the load on the material of the inner walls of one cell is compensated by the compacted material of the adjacent cell, and the extreme side (or located around the perimeter) do not have such compensation, as a result of which their walls are subjected to significant tensile loads. The implementation of the entire design of the geomatrix from a material of increased strength will lead to the waste of such material.

The objective of this technical solution is to create a geomatrix with equal strength under the action of the calculated loads structural elements.

The technical result consists in expanding the arsenal of tools to strengthen and stabilize weak bases, namely, geomatrix designs.

This is achieved by the fact that the geomatrix is formed by ribbons mounted on an edge and having means for connecting adjacent geomatrixes from tapes of synthetic permeable woven material, curved to form each ribbon in the plan of rectangular cells open from one of the sides, to which are sewn along bending lines facing it the subsequent curved tape also closes rectangular cells open from one of the sides of the previous tape, and the open cells of the first and last curved tapes are closed by a sewn-in and along the edges of these cells inserts in the form of segments of tapes, and on the side of the base of the geomatrix, a membrane (a polymeric material brought by external forces into a state of tension and possessing elasticity as a result) is fixed by firmware on the bent out tapes with its outflows beyond the geomatrix contour along its two adjacent sides. The first and last tapes forming it and the inserts sewn into them made of synthetic water-permeable woven fabric are made of a material whose tensile load (tensile strength) exceeds the tensile load of the tapes located between them, and the membrane is fixed by piercing the bends to the outside of the tapes, one of which is a tape from a material with the mentioned increased tensile strength. The geomatrix is equipped with means for attaching it to the device for tensioning and laying, made in the form of loops or cords sewn to the ribbons. The membrane is additionally fixed to the tapes made of filtering synthetic material located within its contour with seams longitudinal in the plan tapes. Or the membrane is additionally fixed to the tapes made of filtering synthetic material located within its contour with seams that are transverse in the plan to the tapes.

The technical solution is illustrated by drawings, where:

- in FIG. 1 shows a top view of the geomatrix with a diagram of the lines for piercing tapes and membranes;

- in FIG. 2 is a cross-sectional diagram of a line for piercing a tape and a membrane.

The geomatrix contains ribs 1 mounted on an edge and having means for joining adjacent geomatrices of synthetic water-permeable woven fabric (TU 8288-112-53578992-2015 with amendment 1 “Technical fabric TG-500 GHV”). Breaking load (tensile strength) of a strip of fabric TG-500 GHV-U with a size of 50 × 200 mm, (according to the specified TU) based on - not less than 550 kgf, for weft - not less than 380 kgf. The breaking load of a strip of fabric (increased strength) TG-500 GHV-U with a size of 50 × 200 mm, (according to the specified TU), based on - not less than 550 kgf, for weft - not less than 380 kgf. Tapes 1 are zigzag bent with each tape forming rectangular cells 2. Each tape also has curved tape 3 sewn along the bending lines facing the tape 1 and closing rectangular cells open from one of the sides of the previous tape. The open cells of the first and last curved ribbons that are formed during the stitching of ribbons are closed by inserts 4 in the form of segments of ribbons sewn along the edges of these cells. From the side of the base of the geomatrix, a membrane 5 of synthetic filtering material with its outlets 6 behind the contour of the geomatrix along its two adjacent sides is fixed by firmware on the tapered bent outward tapes. The first and last forming tapes made of synthetic water-permeable fabric material and the inserts sewn into them are made of a material whose tensile strength exceeds the tensile strength of the tapes located between them — made of technical TG-500 GHV-U fabric, the membrane being fixed by flashing outwards of tapes , one of which is a tape made of a material with the mentioned increased tensile strength. To realize the purpose and maintain the vertical position of the tapes during the laying process, the geomatrix is equipped with means for attaching it to the tensioning and laying device, made in the form of loops or cords sewn to the tapes. The membrane (which is in the process of operation in a stretched state) is additionally fixed to the tapes of filtering synthetic material located within its contour with seams longitudinal in planes to the tapes. The membrane can be additionally fixed to the tapes made of filtering synthetic material located within its contour with seams transverse in the plan to the tapes.

When constructing a base reinforced with a geomatrix, it is temporarily connected by means of fastening (for example, loops, ties) with the frame, and installed together with it on the frame supports so that the fastening means remain at the top, and the membrane with the frame supports installed on it, at the bottom. In this position, the cells are filled with bulk material and compacted while maintaining the vertical design position of the geomatrix tapes. The increased strength of the extreme tapes (TU 8288-112-53578992-2015 with amendment 1 “Technical fabric TG-500 GHV”) preserves the integrity of the geomatrix during the compaction process, preserves its shape, determined by the project of work, and allows to reduce material consumption (costs) in the process manufacture. When filling the cells with bulk material and compacting them, an additional stretching of the base membrane occurs, which improves the working conditions of the geomatrix as a whole. The presence of bends and their connection with the outlets of the membrane can improve the reliability of the connection of geomatrices with each other to ensure evenness and elimination of washing out the junction of the geomatrix.
