What is an Embankment?
An embankment on soft ground is just a man-made mound made of earthy elements such as stones and sand that is appropriately compressed to sustain the elevation of a highway or railway over the ground level. Engineers & constructors can use geosynthetic reinforcements for the stability of created embankments by regulating settlement and deformation.
Why SF Geogrid® for Embankments on soft ground?
The sand grains will find something strong to press against considerably sooner if they are being used. By enabling a few of the interlocked particles within the soil to penetrate through the grid’s aperture, they enable to transfer of the load received by the sand grains. The particles that have passed through apertures are then driven into to the geogrid‘s rib cage by the forces above, generating tension in the ribcage and distributing the tension over the surface area of the geogrid material.
An increased surface area equal to less stress on the soil beneath the geogrid reduced movement of soil above the geogrid, overall greater soil structure stability.
Geogrid material specification has tensile properties ranging between 20–600 kN It’s employed in basal reinforcement projects including the design of embankments on soft soils and reinforcing soil structures that are subjected to high force.
What is soil erosion?
Soil erosion happens when the shear strength is caused by external factors like wind & flowing water exceeding the shearing impedance of the sand particles. Shear resistance must be improved to mitigate soil erosion.
Riverbanks might break into the ground due to soil erosion, or road or railway embankments can collapse, resulting in major disasters. The uppermost layer of soil in cultivated fields may become eroded, resulting in a loss of rich soil. According to reports, the topsoil is swept and cleaned ten times quicker than natural renewal in the United States and 30 to 40 times faster in India and China.
Vegetation cover, rip-rap, turfing, stone pitching, mats, gabions, and groins are some of the ways used to control soil erosion. Geosynthetic materials, on the other hand, have grown in popularity during the previous fifty years.
Soil Erosion Characteristics
- The intensity, amount, and frequency of rain and the slopes of the land and soil permeability are the key elements that influence soil erosion.
- Shoreline, Splash, sheets, shoreline, rill, or gully erosion are the various kinds of erosion.
- Separation, transportation, & deposition are the main processes in erosion
How SF Geogrid® Material Control Soil Erosion
They are useful in reinforcing soil for retaining walls.
Reinforcement Grids Application for erosion control
- Waste containment
- Sub-grade stabilization
The reinforcement grids must be robust enough to sustain the tensile reinforcement strain while properly transferring that force into the ground. Grid reinforcement wall material must be biologically inert as well as chemically resistant such as alkalis & acids.
Geogrids for erosion control made from biaxial Polyester and uniaxial polyester geogrid are used to boost the effectiveness of poor subgrades. Shear failures and Pumping are reduced when dynamic forces are distributed across a larger region, leading to more excellent subgrade load-carrying capability.
The base reinforcing with biaxial-polypropylene ground reinforcement grids is also highly effective. The openings of geogrids interact with the ingredients of the base, trapping them & preventing them from dispersing laterally. As a consequence, base materials could be reduced by up to 30%.
Key Feature
- To increase shear strength, geotextiles can be placed in compacted fill embankments.
- Geotextile grids can be paired with low-strength soils to increase shear strength.
- Landslide repairs can benefit from geotextile tensile soil reinforcement as well.
