Applications:

1.Construction of subgrade

One of the key factors in the design and construction of routes that passes through loose ground, is reinforcing and stabilizing road sub grade, if there was no access to appropriate sub grade, road pavement also will disappear gradually. There fore Meshiran net scan be used between the sub grade and the sub base since due to technical character is tics of these nets,traffic load would be distributed better on the sub grad eand prevents local and as ymmetricsettleme nets. The main advantagesofusing Meshiran geo grids in asphalt infrastructure, is top reventasphalt rutting, which is because of high traffic and particularly heavy vehicles load.

Advantages of Meshiran nets to providestable foundation

• seperation of Subgrade and Subbase materials and prevention of Subgrade materials of moving out away from the load
• minimizingsettlement withuniform distribution of load according to it’s vast area
• increasing tensile strength due to friction between the net and the soil, also it improvesshear strength of soil
• because of reticular formation itreducesandeliminates thepore water pressure
• using of these nets will totally prevent destructive phenomena such as reflection cracking

2. Reclamationofswampy and coastalland

One of the important useofgeogridnets, is reclamationand recycling of the land fromthe sea. Thepurpose of these operations is using infoundation of marinestructures orwalls and protecting and stabilizingbeaches andcoastallands.

Recyclingofland fromthe seais usuallydoneaccording tothe figure. Heregeogridnetscauseuniform distributionofthe load andprevent subbase material of moving out away from the load and separate that from the subgrade material.

Meshirangeogridis very suitabletouse inswampyareas. Usuallythereneedstotransport lots of materialsatthese areasbutdue topoorquality of soil, Itis possibleonlywhen youendurehardshipand and expend a lot.

Apertures of geogrids, sets wateruniform motion according toit’ssurface,andprovide a solidplatformforpositioning and stabilizing offillermaterials.

This action causes significant decrease in settlementparticularly in swampyareas, and provides required adhesion of materials for operation progress.

3.Construction of bracing structures, embankments,dikes

Flood controlandprotection of riversagainsterosion

Mostcanalsinclude controller structures such ascutoff, stilingandcatchmentbasins which can be designed by using gabions madeofgeogrids.

Long life of these products and working easily withthemare some of the advantages of using them in such cases.

Using of geogridsinconstruction of cylindrical gabions isknown asa simpleandeffective way to preventerosion of theriverbed.

Construction ofcoastal wall

Using of polymer gabions, coastalwalls can bedesigned andconstructed.

The advatages of these walls are ease of installation, high strengthandvery low costs compared to other methods.

Properties of Meshiran geogrid

• made of high-strengthpolymer
• fullprotectionagainst corrosive agents insea water
• transportationandease of installationin site
• goodflexibilitycompared tothe ground surface

4.Reinforcingsoil(reinforcing subgrade)

Meshiran geogrids can solve problems thatheavystructuresand embankments cause on poor soils without the need forpilingandexcavation andembankmentoperations (replacing weakmaterials with resistantandcoarse grained materials).

This action is possible byplacinglayers ofgeogridinloose soilwhere they reach the failure surface.

Also embankment can be constructed in aclosetfull ofcoarsematerialthatismadeof polymernets.

This willstrengthenbackfill’s infrastructure and substantiallyreduce asymmetricsettlement whichcausesa lot ofdamageto the foundation with the possiblity of proper drainage.

5.Prevention of erosion of slopes

Erosion of soil slopes bywindandrain leads toinstabilityand eventuallyfailureof the slope andmaintenanceof theseslopeswithout usingofMeshiran geogridswould cost too much.

Byplacingalayerof polymernetthatfacilitatesandacceleratesthegrowth ofvegetation,erosioncan bepreventedwiththe use ofexistingnatural conditions.

Meshiran nets havethe followingthree main applications:

• by creating ashieldforthenewly plantedgrass, aperfect environment would be providedforthe growth ofplant rootsin soilslopes
• causetraction andgrip of vegetation against torrentialrains
• reducing theimpact ofrainfallonsoil surfaceandgroundwaterconductivity alongthenet

6.Reinforcing theinfrastructure ofrailway

Using Meshiran geogrids make it possible to build reliablerailways in a short time onpoorsoil, also maintenanceofthat would becheaperandeasier.

Repair of subbase of railways or ballast isone of the commonrail systemoperations in each country that requires majorannualexpenditure. Geogrids interlock with ballastmaterials, not only enhancebearing capacityandreducecosts but alsopreventproblems such asasymmetric settlement.

Advantages ofgeogridnetin theconstruction projectsand maintenance ofrailroads:

• Enhancingthe capacity ofcargo carriage
• Increasing speed of train
• Reducing costs of maintenance and railwayballast
• Comfortand more safetyof passengers
• Increasing theuseful life ofrailroads

7.Preventing oflandslides, falling of rocky cliffsandearthslopes

Erosion of rocky cliffs gives opportunitiesforlooserock fragmentswhich have beenweatheredandhave potantiol to fall. With application of polymernetsplacingon the slippery surfaceandrocky cliffs, prevention of disaster ordamage tostructures (roads, bridges, buildings, etc) would be possible.

Thisstrategy, especially in mountainous and coldareas of the country wherethelarge piecesof stone, crush due to drastic changes intemperature and freezing orbecause of raining, isveryeffective.

8.Applicationin drying systemfor fruits and vegetables
