General concept and process of manufacturing a geogrid

A geo-reneter belongs to geosynthetics, which appear in the form of two- or three-dimensional structure of honeycombs. For its manufacture, strips of paintings from polyester, polyethylene or polypropylene tape are used. These fragments are connected using high -strength welds.

In the case of stretching the working surface, the formation of a strong linear frame occurs, which reinforces filled cells with soil, sand material.

A geo renet is a reliable protection of slopes, slopes and soil from shedding or destruction. To avoid landslides and siltation of water areas also use a geogrid. She copes with the strengthening of the shores perfectly. The georstant is rightfully called one of the most durable materials of reinforcing purposes. The maximum period of use of the geogrid exceeds one hundred years. The geo -realt is resistant to hydrolysis, gasoline, acids, alkaline solutions, diesel fuel.

During its manufacture, the heated polyethylene or polypropylene perforated sheet with the help of special equipment is stretched. In this case, the drawdown of randomly oriented long -like molecules in an ordered oriented structure occurs.

There is a volumetric gearstat - it appears in the form of a design of honeycombs or tape, which are reliably fastened to each other. It is easily established, stable before decay and exposure to chemicals. The term of its use exceeds fifty years.

Geotextiles used in the process of manufacturing a geogrid are fabric and non -discharge. To combine polypropylene strips, thermal or ultrasonic welding is used. To combine strips made of geotextile materials, stitching is used, during which high -strength connections are formed.

Therefore, a volumetric geo -type geo is light, mobility, is used in the process of protecting building soil and soil from deformation.

Geotextile geogrids begin to displace plastic and metal analogues, due to the convenience and simplicity of installation and small weight. The installation does not require additional equipment.

The main functions of the geogrid is:

• prevention of violation and deformation of soil surfaces,
• ensuring water passage,
• protection of the road surface from settlement,
• fixation of crushed stone and its protection against spreading in a horizontal plane,
• increasing the bearing capacity of the road surface,
• Ensuring environmental safety.

In order to buy a geogrid, you should first draw the calculations of the amount of this material.

The price of the price is determined by such factors:

• Type of geogrid,
• amount of material,
• manufacturer of the geogrid,
• maximum load,
• lifetime.

Advantages and scope

The geo -realt has a wide sphere of application. It is used to strengthen various structures of both construction and industrial purposes.

A geo -realt allows not only to strengthen the base, but also protects the top layers of road clothing from destruction. For example, in the process of using geo -reasons for strengthening the asphalt concrete coating, its strength, elasticity, durability, stability before the formation of cracks and temperature differences are increased.

There is a redirection of vertical loads from vehicles to horizontal ones, thus increasing the bearing capacity of the coating and the appearance of cracks and stretching stresses is prevented.

Also, a polymer gears can strengthen the fortress and prevent the shedding of weak soil.

The main use of the geogrid is manifested:

• in the process of reinforcing loose or heterogeneous soil,
• for anti -erosion defense of slopes,
• to fix and prevent the destruction of a road foundation,
• for the construction of retaining structures with various heights and angle of laying,
• In the process of strengthening the channel or the shores of a water flow, a reservoir or a river,
• When conducting landscape works associated with the landscaping of lawns, sports grounds or automobile parking.

The use of georetes in the construction of civil purposes leads to:

• strengthening of weak soils in the region, in those places where limited access to substances of non -nonsense is observed,
• strengthen the inclined surfaces or slopes,
• strengthening the rivers from erosion,
• the device of the walls of the retaining purpose,
• construction of sports courts or sports grounds,
• construction of platforms for helicopters,
• the device of terraces that have several levels,
• The construction of various structures in landscape design.

A flat -type georset is used during the construction or reconstruction of roads and helps to improve quality and evenly distribute the load on the highway.

The use of a geogrid in railway construction helps to strengthen and strengthen the soil under the railway.

In the process of building temporary roads in the oil industry industry, a geo -realt is also used. It helps to increase the bearing abilities of the walls along which oil is extracted.

Georste - a universal material that has such advantages:

• stability before corrosion can significantly increase the life of this material;
• The use of a geogrid is economical, since it is able to perform its functions for more than fifty, and in some cases a hundred years, thus, for such a long period of time, additional strengthening of slopes, coasts, highways or railway tracks is not required;
• The geo -reneter has a high bearing capacity and is able to withstand very high loads;
• In the process of use, this material is practically not deformed, which is very important, for example, when arranging slopes;
• The georstabol is stable before the effects of salts, alkaline or acidic solutions;
• This material is stable before the formation of mold, fungus and exposure to microorganisms.

The main types of geogrids

Georstens differ in diameter of cells, they come from twenty to forty centimeters. To improve soil drainage, geogrids are made with the presence of perforated faces of cells.

In the ratio with the material from which the georechens are made: are highlighted:

• geotextile,
• polyester,
• polypropylene,
• Polyethylene.

1. The frame gearshot is a strip of geotextile canvas, which are characterized by high density. Compared to a polyethylene geo -sheet, a geotextile geo rehears has less hardness and rigidity. Due to the presence of such a structure, the provision of good drainage is obtained and friction with the materials with aggregates increases. The scope of application is limited to increased density of the soda parts, roads, embankments and landscaping of the premium zones.

2. Polyesh geopers are geosynthetic materials that are used to strengthen soil soil, such as crushed stone or sand.

3. Polypropylene geo -translates allow you to stabilize and strengthen the soil, which with low bearing capacity.

4. Polypropylene geo -translates solve the problem of strengthening stone materials and soils, which are characterized by the presence of low bearing capacity.

In relation to the method of production, the geogrid is divided into:

• flexible or fabric -looking
• Hard or thermally glued appearance.

Tough geo -translates are:

• single -axial,
• biaxial.

The production of flexible or fabric georezes is similar using weaving technologies. Their production requires high -strength synthetic threads, at the end of the production process, they are covered with a special polyvinyl chloride layer, which provides protection against ultraviolet radiation.

There is another type of georetis that are made using modern technologies using polyvinilalogol. They differ in the possibility of lengthening by three to five percent.

The lattices of a rigid or thermally glued appearance are made using stripes that are located perpendicular to each other, and at the intersection, during heating, they are glued.

The process of manufacturing hard georetes resembles the melting of a single flat area, which is based on polypropylene or polyethylene. On this canvas, special holes are made that allow you to form a grill. Depending on how stretching is carried out, if one way, then the georstopa becomes the same -axle, and if in two, then a friendly one. These two types of georetes differ in the way of perception of the load. Twosnoye are able to take pressure from both sides, and the same -axle - from one.

Spearry gears - preparation of coating and laying

In this case, we propose to consider the styling of a volumetric type of geogrid. First of all, a number of preparatory work should be carried out. Start by checking the drawings of the area and unpacking geotextiles.

You should specifically know which slope is planned to strengthen. Then you need to prepare his sole and trenches.

Decide on the plan for installing a geogrid. There are two ways:

• transverse - from the slope to the central part,
• longitudinal - in parallel with the slope.

In the plan, the styling method is regulated. Using the pegs, indicate the layout of the material. Expand, and then stretch the geogrid.

After completing the preparatory work on cleaning leaves, vegetation and garbage, the process of installing a geogrid should begin. It is recommended to use a protective layer from a non -cup -type geo.

It is fixed over the entire area of \u200b\u200bthe slope, and the fixation is overlapped with a slope of the slope in the horizontal surface. In the place where the zero mark is placed, work is carried out to depress the geogrid.

The fixation of each module occurs in the central part using plastic anchors or other fasteners. Counterators are installed in a checkerboard pattern directly on the horizontal part of the geogrid. The modules are connected using a special pneumatic stepler or anchors. When the installation process is completed, it is necessary to check the evenness and correctness of the tension of the geogrid.

The next stage involves filling out pre -established cells. This process directly depends on the conditions in which the geo -rein is mounted. If the soil is in place, then the cells are filled with it, otherwise, the soil should be brought to fill them. For these purposes, the use of crushed stone, concrete or a mixture of several soil breeds is also suitable. To fill the cells, you do not need a special construction equipment, just use a bulldozer or escalator with the presence of a reverse bucket.

The option of unloading is possible immediately to the cells, and then they are gradually leveled. The height of the filling of the filler should exceed the height of the cells by half a meter or more.

The final stage of the installation of the geogrid is work on the compaction of the aggregate. This stage also depends on the type of material and working conditions. In order for the filler to quickly compact, you need constant humidity in the process of ramming.

Recommendations for the installation of a geogrid

1. During the installation of reinforcing piles of the L-shaped shape in the upper part of the slope or near the trench, they should not be installed completely in the soil. The interval between the centers is influenced by the type of geogrid:

• with the cell of which the ramer is 21x21, the interval is - 21 cm;
• In the event that the size of the geogrid is 40x40, then the distance is 40 cm.

2. Fixation of the edges of the geogrid occurs using fasteners in the form of pins, anchors or other elements.

3. Before filling, be sure to check each cell for full stretch.

4. There should not be irregularities on the geogrid, it should fit tightly to the surface of the soil.

5. It is recommended to use three or four anchors per 1 m of gears, which are located in a checkerboard pattern.

6. The angle of slope of the slope has a direct influence on the height of the cell. If the angle does not exceed ten degrees, then the height of the cell is no more than five centimeters. In the case of an angle of 10 to 30 degrees. It is necessary to use a gears with a cell size up to one meter. With an angle of inclination of 30-45 degrees, the size of the cells is one and a half or two meters.

7. In the process of filling the geogrid, it is not allowed to scatter the filler from a height of more than one meter. And if the size of the cell is about 40 cm, then the height of the filler supply should not be more than 60 cm.

8. Filling out of the birch, and then gradually go to the sole.

9. Be sure to pour the material in such a way as to get it in excess, since after filling it will still be compacted.

10. Filling of concrete is carried out to the upper part, and then it is compacted, then poured again.

11. Filling a geogrid using vegetable soil is five centimeters or more than the height of the cell.

12. Folding using mineral material should exceed the level of the cell by two and a half centimeters.
