Composite geotextile (composite anti-seepage membrane) is divided into one cloth and one membrane, which has high physical and mechanical properties such as high tensile strength, tear resistance and bursting performance. The product has the characteristics of high strength, good ductility, large deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance and good anti-seepage performance. Meet the civil engineering requirements for anti-seepage, anti-seepage, reinforcement, crack prevention and reinforcement in water conservancy, municipal administration, construction, transportation, subway, tunnel and engineering construction. It is often used in the anti-seepage treatment of dykes and drainage ditches, and the anti-pollution treatment of garbage dumps.
The role of two cloth and one membrane geotextile;
1. Short-fiber geotextiles have many functions: when water flows from the fine soil layer to the coarse soil layer, the outstanding air permeability and water permeability of needle-punched geotextiles are used to allow water to pass through and effectively intercept soil particles, spun yarns and small rocks, thereby maintaining the stability of the water and soil engineering.
2. Use polyester staple fiber needle-punched geotextiles to block building materials with different physical properties (such as soil and sand, soil and concrete, etc.). ). Make two or more kinds of data not lost or turbid, maintain the overall structure and function of the data, and strengthen the bearing capacity of the structure.
3. Geotextile is an excellent water-conducting material, which can form drainage channels in the soil and separate the remaining liquid and gas in the soil structure. The cracking strength is high, up to 20KN/m or more, and it has good creep resistance and corrosion resistance. Needle-punched geotextiles are used to enhance the tensile strength and deformation resistance of soil, increase the stability of building structures, and improve soil quality.
4. When the protective water of the geotextile scours the soil, it is useful to diffuse, transfer or distinguish the concentrated stress, so as to avoid the soil being damaged by external force. It is very useful to protect the soil, disperse, transfer or distinguish concentrated stress, and prevent the soil from being damaged by external forces.
Geotextiles are made without any chemical additives, mainly polyester filament needle-punched non-woven geotextiles, without high temperature heating, and are one of the typical qualified environmental protection building materials. At the same time, filament geotextiles have also made some progress and development in environmental protection. The packaging meets the requirements of waterproof, moisture-proof and anti-corrosion.
1. With the cardboard tube as the mandrel, it is made into a coil shape, the amplitude is horizontal, and the length is vertical;
2. The finished product is packed with coated woven fabric;
3. Both sides of the coil are packed with coated woven cloth, and the product name, weight, size (thickness, width and length), manufacturer, production batch number, production date and supplier address and contact information are indicated.
4. Each roll is equipped with two 2.5-ton slings. Of course, the greater role is to satisfy people's pursuit of environmental protection, and it is also a potential welfare policy for the benefit of future generations.
