Gruntovaya

 

(57) Abstract:

The invention is intended for use in building constructions, used for strengthening, improving stability of ground objects railroad tracks, roads and their arrangement. In gruntovaya representing a grid frame of galvanized metal wire with a filler, a frame provided with an inner cover made of synthetic geotextile material or fiberglass, and the filler is ground or dispersed, including a heat insulating material with mechanized filling and sealing filler, mostly pressing. As the dispersed material used asbestos waste, tailings processing plants, granulated slag, clucosamine waste power plants, burning rock mining, peat. Gruntovaya, besides simplicity and manufacturability of a design, the possibility of using local soils, dispersive materials can be disposed of and waste from industrial production. 1 C.p. f-crystals, 2 Il.

The invention relates to structures used for strengthening, improving stability of ground objects VC the embankments and river banks from the effects of fast - and burnnotice water. Gabions are in the form of boxes, mattresses cylindrical shape. Materials for the manufacture of gabions are flexible wire for mesh netting and iron rods for the device frame. Material to fill the gabion cages are rocks solid rock, mostly heavy and subvillages water-resistant breeds. The face stones of the largest. Used gabion laying on the gravel preparation Connect the gabion knitting with wire. Gabion mattresses are less height and are used as clothing, coverings for slopes [1].

The drawbacks of gibonov are korrigiert metal reinforcement, the need for a large number of expensive stone to fill the gabion cages and therefore limited scope, high volume of work with many operations manual high cost.

Known gabion, Maccaferri (Maccaferry) [2] was chosen as a prototype. Gabion, Maccaferri is performed in the frame of flexible galvanized wire with double twist. Material for filling is stone rocks and riverbeds. Filling the stone is done manually with podborochny design and flat shape) are used for regulatory arrangement in riverbeds, for retaining and supporting structures for protection of slopes of embankments from erosion.

The disadvantages of stone gabions, Maccaferri are limited in their application because you fill the frames with stone, which is possible only in the presence of stone quarries, for example in mountainous areas with rocks or in the course of mountain rivers; high volume of work manually when filling the grid frames stone with matching front facing stones, high cost, because the design is the need to use expensive stone.

The claimed invention eliminates these drawbacks are: expanding the scope of gabion structures for device fastening, holding, catching, protective structures, thermal insulation and other coverings and pillows. This reduces cost, reduced labor intensity.

This is achieved by the proposed gruntovaya containing a grid frame of galvanized metal wire, which according to the invention provided with an inner cover made of synthetic geotextile material or fiberglass, and the filler is ground or dispersed, including Chi is disclosed by the drawings, where in Fig. 1 shows gruntovaya consisting of frame made of galvanized metal mesh; it placed the inner cover of the geotextile or fiberglass on the size of the frame and the filler is ground or dispersed material, which fills the frame of the hopper, conveyor, etc., mechanically) and compacted, mostly pressing. After closing the lid, which is secured by a flexible wire, gruntovaya in the form of a block can be used in the construction of objects.

As the dispersed material can be used in industrial waste: asbestos waste, tailings processing plants, slag granulated steel mills, clucosamine waste power plants, burning rock mining, vermiculite waste and others, as well as peat and other local materials.

Technologically filling gruntovaya local ground or dispersed material mechanically seal can be made on special areas or fields, equipped with the necessary mechanisms and press facilities, places of paving, installation of structures machinery for filling,drop frame granulated slag, klaksonami, peat, which have teploizoliruyuschih properties, gruntovaya can be used as insulating elements.

Scheme of possible applications of gruntovaya in road and other structures shown in Fig. 2:

1. In podblast the area of the railroad tracks as protivodetonatsionnuyu, protivopozharnoi pillows, when filling the frame dispersed insulating material.

2. At the base of the mound to strengthen the weak base, increasing its strength, bearing capacity.

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

4. For bell-less variant of the subgrade at the supports artificial structures: bridge, viaduct and other

5. For constructions roadbed - the embankment of the second track, eliminating the need for a longer culvert.

6. For temporary facilities - warehouses inert and binding materials on the concrete nodes, storage, Parking lots and other temporary shelters.

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

8. For retaining structures - retaining walls and other design the scrap, for example peat, as the insulating cover of the slopes for the conservation of underground ice in the conditions of permafrost.

Possible other uses of gruntovaya: barajneh devices, foundations of roads, fences and other, including along and instead of concrete structures. When applied to the soil seed of perennial grasses may landscaping designs from grancolombiano, aided by a mulch cover geotextile. When filling in the case of gravel-pebble materials can be used gruntovaya in temporary streams.

Thus, when used in gruntovaya local soils, dispersive materials reduces the complexity and cost with a simple application techniques, opportunities of use of gabions in the steppe and forest-steppe regions for a wide range of road construction and arrangement and stability of earth structures.
