Abstract

FIELD: building structures used in strengthening, and increasing of stability of ground objects of railway objects of railway bed, motor roads and their construction. SUBSTANCE: ground gabion presents gaze framework from zinc-coated with filler. Framework has internal cover from synthetic geotextile material or glass cloth. Filler is used in the form of ground or dispersed heat-insulating material with mechanized filling and compaction, mainly, by pressing. Dispersed material is used in the form of asbestos wastes, tailings of concentrating mills, granulated slag, slag-ash wastes of power stations, burnt rocks of mine workings and peat. Ground gabion is simple in design and adaptable to manufacture. It allows using of local grounds, dispersed materials, and utilization of industrial production wastes. EFFECT: higher efficiency. 2 cl, 10 dwg

Description

 The invention relates to structures used to strengthen, improve the stability of soil objects of the railway track, roads and their arrangements.

 Known gabions for protecting slopes of embankments and river banks from the effects of fast and stormy water. Gabions are made in the form of boxes, mattresses of a cylindrical shape. Materials for the manufacture of gabions are flexible wire for weaving mesh and bar iron for the device frame. The materials for filling the gabion frameworks are stones of hard rocks, mainly heavy and slightly weathered waterproof rocks. Facial stones are the largest. Gabion masonry is applied on gravel preparation. Gabions are connected with knitting wire. Gabion mattresses are of lower height and are used as clothes, coverings for slopes [1].

 The disadvantages of the described gauges are the corrosion of the metal reinforcement, the need for a large amount of expensive stone to fill gabion frames and, accordingly, the limited scope of their application, the high laboriousness of many manual operations performed by hand, high cost.

 Known gabion Maccaferry (Maccaferry) [2], selected as a prototype. Gabion McCaffery is made in the form of a frame made of flexible galvanized wire with double torsion. Rock filling material from river channels serves as a material for filling. Filling with stone is done manually with the selection of facial ones to create flat surfaces for facing purposes. Such gabions (as well as Renault mattresses of similar design and flat shape) are used for regulatory arrangements in river beds, for retaining and supporting structures, to protect the slopes of embankments from erosion.

 The disadvantages of the stone gabions of McCaffery are their limited use, since it is necessary to fill the frames with stone, which is possible only in the presence of stone quarries, for example, in mountainous conditions with rocks or in mountain river beds; the high laboriousness of manual work when filling the grid frames with stone with the selection of facing facing stones, high cost, since the design is associated with the need to use expensive stone.

 The claimed invention eliminates these disadvantages: the scope of application of gabion structures for the device of reinforcing, retaining, trapping, protective structures, heat-insulating and other coatings and pillows is expanding. At the same time, the cost is reduced, the complexity is reduced.

 This is achieved by the fact that a soil gabion is proposed containing a wire mesh frame made of galvanized metal wire, which according to the invention is provided with an inner cover made of synthetic geotextile material or fiberglass, and the soil is used as a filler or dispersed, including heat-insulating material, compacted by compression, mainly.

 The invention is disclosed in the drawings, where in FIG. 1 shows a soil gabion consisting of a frame made of galvanized metal mesh; it contains an inner cover made of geotextile fabric or fiberglass to the size of the carcass and aggregate - soil or dispersed material that fills the carcass from a hopper, conveyor, etc. mechanized and compacted, mainly by pressing. After closing the lid, which is fixed with a flexible wire, a block-shaped gabion can be used in the construction of objects.

 Industrial production waste can be used as dispersed material: asbestos waste, tailings of processing plants, slag granulated metallurgical plants, slag ash from power plants, burnt mines, vermiculite waste and others, as well as peat and other local materials.

 Technologically, filling gabiobion with local soil or dispersed material by mechanized compaction can be done at special sites, landfills equipped with the necessary mechanisms and press systems, at places of installation, installation of structures with mechanisms for filling, compaction, installation, or directly at places of installation in soil structures.

 When filling the frame with granular slag, slag ash, peat, which have heat-insulating properties, soil packs can be used as heat insulating elements.

Schemes of possible applications of ground gabions in road and other structures are shown in FIG. 2:
1. In the sub-ballast zone of the railway track as an anti-deformation, anti-cushion pillow, when filling the frame with heat-insulating dispersed material.

 2. At the base of the embankment to strengthen the weak base, increase its strength, bearing capacity.

 3. For embankments with vertical and steep slopes in cramped conditions.

 4. For a non-conical version of the subgrade at the supports of an artificial structure: a bridge, overpass, etc.

 5. For subgrade structures - embankments of the second path, which eliminates the need for lengthening culverts.

 6. For temporary premises - warehouses of inert and binders on concrete nodes, for storage, parking of cars and other temporary shelters.

 7. For catching structures - walls, shelves in conditions of rockfalls.

 8. For holding structures - retaining walls and other structures that increase the stability of slopes and slopes.

 9. When filling the cover with heat-insulating material, such as peat, as a heat-insulating coating of slopes for conservation of underground ice in the conditions of permafrost.

 Other options for the use of soil gabions are possible: for barrage devices, bases for highways, fences and others, including along with instead of concrete structures. When seeds of perennial grasses are introduced into the soil, landscaping of structures from ground gabions is possible, which is facilitated by the mulching coating of geotextiles. When filling the cover with gravel and pebble materials, it is possible to use soil gabions in temporary streams.

 Thus, when using local soils and dispersed materials in ground gabions, the laboriousness and cost are reduced with a simple application technology, the possibilities of using gabions in the steppe and forest-steppe regions are expanded for a wide range of road structures and arrangement and ensuring the stability of soil structures.
