PP Plastic Two-Way Geogrid

Industrial PP triaxial geogrids have excellent mechanical properties when the pre-punched diameter is in the range of 2.5 mm to 3.0 mm. These characteristics are mainly due to the structure of the geogrids.

The tensile behavior of PP plastic two-way geogrids can be predicted using numerical simulation analysis. This analysis is easy to carry out without conducting experiments, saving time and material resources.

PP Geogrid

PP biaxial geogrid is made of virgin polypropylene (PP) and carbon black, produced through extrusion, punching, heating, longitudinal stretching and transverse stretching. It has high tensile strength and good interlock capacity. It is widely used in highway, railway and slope protecting projects. It can strengthen the soil and reduce its collapse potential, thereby increasing its loading capacity and service life. It is also easy to construct, reducing project cost and maintenance costs.

The shear and tensile behavior of a PP biaxial geogrid can be predicted using numerical models. These models can show how the force is PP plastic two-way geogrid transferred from a shear bar to the surrounding sand. They can also show changes in the distribution of displacements and forces as the load is applied to the geogrid.

Several studies have examined the effects of defects and installation damage on PP geogrids. Defects can cause significant reductions in mechanical properties. These defects include punctures, tears, flaws, bent ribs, and variability in aperture sizes. These defects can be caused by manufacturing, shipment, storage, and installation. Some studies have found that geogrids with these defects can have lifetimes that are significantly less than those predicted by the manufacturers. These lifetimes can be improved by reducing the exposure time and incorporating anti-aging materials into the product. Other factors that influence the long-term behavior of a geogrid are temperature and site conditions.

Uniaxial Geogrid

PP biaxial geogrid is a type of plastic geosynthetic material that strengthens the bearing capacity of soil. It is used in highway, railway and slope protecting projects. It can be used to stabilize soil, reduce the depth of rutting, and prolong pavement life. It can also reduce construction and maintenance costs. It is a high-performance product with excellent interlocking capability and tensile strength. It can be made into various shapes and sizes, which make it easier to use in different applications.

Generally, geogrids are constructed from polymers such as polyester, polyvinyl alcohol and polyethylene. They can be woven from yarns, heat-welded from strips of material or produced by punching a regular pattern of holes in sheets of material and then stretched into a grid. Geogrids are also categorized based on their woven pattern.

Biaxial geogrids have ribs that run in both directions, while uniaxial geogrids have ribs running only in one direction. Both types are available in a wide variety of colors, materials and finishes. They are mainly used in civil engineering applications, such as strengthening and stabilizing low load-beating soils and constructing walls that require vertical support.

This product is easy to construct and can be placed in the ground in any direction. It is ideal for building foundations and roads, because it can withstand large loads. It can also prevent soil erosion, as it has a strong interlocking effect with the surrounding soil or gravel. It is also environmentally friendly and can be recycled after its service life.

Triaxial Geogrid

Tensar TriAx is a high-performance geogrid designed to handle forces in two lateral directions. It combines the proven stabilisation performance of triangular geometry with improved rib and junction geometry to provide exceptional in-plane stiffness. It offers greater radial stiffness than uniaxial geogrids, and also provides superior separation, filtration, and drainage capabilities.

Triaxial geogrids are a cost-effective alternative to bidirectional geogrids for projects that require dynamic stress/loading in two orthogonal directions. They are used in applications where the soil is unstable and needs to be stabilized with a strong, durable material.

To determine the mechanical properties of the triaxial PP geogrid, it was sampled at a length of not less than 100 mm to obtain samples with straight ribs and evenly distributed nodes. The samples were then subjected to a tensile fracture test at room temperature. The results of the tests show that the mechanical properties of the triaxial PP Geogrid depend on the stretching process and the selected pre-punched diameter.

To analyze the influence of the stretching process, Abaqus CAE software was used to simulate the longitudinal and transverse stretching of industrial PP triaxial geogrid pre-punched sheets with different pre-punched diameters. eomembrane Waterproof Geo Membrane The distribution law of stress and strain was analyzed from two aspects: the change law of stress and strain along each path and the change law of stress and strain at special points.

Flexible Geogrid

Biaxial plastic geogrid is a high-strength, lightweight geosynthetic material. It is used to reinforce soil and prevent erosion. Its ribs are oriented at 90 degrees to each other, giving it strength in both directions. This makes it more versatile than geotextiles. The ribs are also more stiff than the fibers of geotextiles, which gives them greater tensile strength.

Unlike geotextiles, which separate soils and promote drainage, biaxial geogrids are designed for soil reinforcement. The shape of their apertures allows soils poured over them to interlock, which increases the load-bearing capacity of the soil. This is especially important for coastal applications, where geogrids help prevent erosion of the retaining wall or seawall.

The polyethylene used to make the PP flexible geogrid is treated with various additives, including anti-ultraviolet and anti-aging, to enhance its corrosion resistance and longevity. These additives help the PP geogrid withstand environmental conditions such as rain, wind, and sunlight. The resulting product is also highly dimensionally stable and offers excellent wear resistance.

It can be used for a variety of permanent projects, such as road construction, railway construction, and slope protection. It can also be used to strengthen retaining walls and tunnels. It is easy to install and does not require special construction machinery or professional technicians. Moreover, it is inexpensive and can save 10%-50% of the project cost.
