Geosynthetics products information and Technology
There are several different types of geotextile. These can be woven or nonwoven. The types of geotextiles are classified according to their traffic and grading. Each type has a different energy index that is the product of the tensile strength of the geotextile and the strain at its maximum strength. There are also tolerances for mass per unit area and static puncture strength. Read on to learn about these different types.
Common reinforcement materials: geogrids, geotextiles and georeinforced tapes, etc. There are two main types of reinforcement in highway engineering: ①The stability of the embankment is insufficient. In order to improve the stability of the embankment and control the settlement of the embankment, geosynthetics are used for embankment reinforcement; ②In order to reduce the uneven settlement between the subgrade and the structure, the subgrade on the back of the platform is reinforced with geosynthetics.
Geosynthetic reinforced soil technology is a new geotechnical technology, but it has developed rapidly. Due to its reasonable structure, good stress conditions, simple construction and significant benefits, it is widely used in various filling projects. It uses synthetic polymers, such as plastics, chemical fibers, synthetic rubber, etc., as raw materials to make various types of products, which are placed inside the soil, on the surface or between layers of soil to strengthen or protect the soil.
Geomembrane is a waterproof barrier material with high molecular polymer as the basic raw material. It has excellent resistance to environmental stress cracking, low-temperature resistance, aging resistance, corrosion resistance, and a large operating temperature range (-60–+60), and long service life (70 years). It is widely used in seepage prevention of domestic waste landfills, seepage prevention of solid waste landfills, seepage prevention of sewage treatment plants, seepage prevention of artificial lakes, tailings treatment, and other seepage prevention projects
Geosynthetics is a general term for synthetic materials used in civil engineering. As a civil engineering material, it uses synthetic polymers (such as plastic, chemical fiber, synthetic rubber, etc.) as raw materials to make various types of products and place them inside, on the surface of, or between various soils. , To play the role of strengthening or protecting the soil.
Geosynthetics, different products have different characteristics and can be used in many engineering fields. It has been applied in geotechnical engineering, civil engineering, water conservancy engineering, environmental engineering, traffic engineering, municipal engineering, land reclamation engineering, etc.
Reflective cracks are caused by the large displacement of the old concrete surface near the joints or cracks that cause stress concentration in the asphalt overlay above it. It includes horizontal displacement due to changes in temperature and humidity, and due to traffic loads. The vertical shear displacement is caused by the action. The former causes concentrated tensile stress in the asphalt overlay above the joint or crack; the latter causes the asphalt overlay above the joint to undergo greater flexural tensile stress and shear stress.
High strength. Due to the use of plastic fiber, it can maintain sufficient strength and elongation in dry and wet conditions. Corrosion resistance, long-term corrosion resistance in soil and water with different pH. Good water permeability. There are gaps between the fibers, so it has good water permeability. Good anti-microbial properties, no damage to microorganisms and insects. Convenient construction. Because the material is light and soft, it is convenient to transport, lay and construct.
Geotextiles are classified into water filtration type, impermeable type, and heat preservation type according to their uses. The width is 0.3 to 18 meters, and the length is unlimited. The thickness of the geotextile is related to the forming method, and the weight per square meter ranges from 16 grams to 900 grams.Geofantex Geosynthetics geotextile could supply 16-2000 grams geotextiles.
Overview: Geotextile is a single permeable material produced from non-woven processes, woven processes, weaving processes, wet-laid processes, etc. using a polymer as raw material. , Water conservancy, water transportation, airport, environmental protection and other basic construction fields, play a role in infiltration, drainage, protection, separation and crack prevention in the project.
