Application field of composite geotextile

Composite geotextiles are mainly used in five areas 1. Environmental protection and sanitation. It has effectively solved the problem of urban solid waste pollution to the environment, and can avoid continuous pollution to the environment. 2. Water conservancy projects are used for dam foundation reinforcement, drainage board for groundwater drainage, diversion and decompression, etc.　　3, various anti-seepage projects such as soft soil foundation reinforcement and drainage of municipal construction engineering　　4, petrochemical system, chemical sewage tank anti-seepage, oil refinery sewage tank anti-seepage, electroplating pickling tank anti-seepage and anti-corrosion, pipeline lining, etc.　　5. Seepage prevention and diversion reinforcement under road traffic facilities and ballasts, seepage prevention and reinforcement of culverts and tunnels, groundwater diversion and moisture protection of circuits). Composite geotextile composite geotextile (composite geotextile) is divided into one cloth and one membrane and two cloth and one membrane. The width is 4-6m, the weight is 2001500g/square meter, and the physical and mechanical properties such as tensile resistance, tear resistance, bursting resistance, etc. High, the product has the characteristics of high strength, good extension performance, large deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance, and good anti-seepage performance. It can meet the needs of civil engineering such as water conservancy, municipal administration, construction, transportation, subway, tunnel, and engineering construction for anti-seepage, isolation, reinforcement, crack prevention and reinforcement. Because of its selection of polymer materials and the addition of anti-aging agents in the production process, it can be used in unconventional temperature environments. It is often used for the anti-seepage treatment of dams and drainage ditches, and the anti-fouling treatment of waste yards. Function: Seepage prevention and isolation. Uses: Geotechnical dams, rockfill dams, stone masonry dams and spreading concrete dams; horizontal impervious overlays in front of dikes and dams, vertical impervious layers of foundations; tailings dams, sewage reservoir dam body and reservoir Construction of cofferdams; The wide application of composite geomembrane in channels and reservoirs has also played a protective role in the ecological environment. Next, we will learn more about this aspect. The ecological slope protection engineering system adopts soft materials to build flexible slopes and retaining walls, and completes the planar greening of reservoirs and slope banks. It truly expresses the construction of the southern area of u200bu200bthe ecological green project that is protected, energy-saving, living, and deep breathing. . The project does not require high energy consumption and high pollution steel, lime, stone and other hard materials, and can also be used to repair vertical or near vertical pen-steep rock slopes, drainage ditches and reservoirs. Composite geomembrane is a new kind of greening goods, it has the advantages of light weight, convenient transportation and easy construction. It is practically used for the greening of three-dimensional, slope and high slopes, so that the moisture can flow in the soil of the bag and the bag. It is the vegetation that loses the necessary moisture, and it will never cause fruit or fruit due to rain or watering. Water and soil are lost, and the composite geomembrane needs a realistic seeding block for eternal plants. It is permeable and impervious to the soil. Grass can grow from the outside or grow in name. It is very good for vegetation. The root system of vegetation can be between the bag and the bag. Growing freely, the root system firmly connects each composite geomembrane into one, building a stable and permanent ecological slope.　　 Anti-chemical erosion The extensive research test indicated that the composite geomembrane has a strong resistance to certain depths of acid-base chemical objects, and can be used in most liquids and heavily polluted places.　The composite geomembrane resistant to biodegradation and destruction of living beings is made of specially formulated materials from the United States, which does not support, attract, or assist the growth of fungi, and does not decay, rot, or metamorphose. The anti-purple inner composite geomembrane contains carbon ink and other anti-UV factors. After 4 deceleration experiments conducted by the GRL, the pressure of 260kpa is imposed at the water-gas interface at 25 degrees Celsius. When the PP of the pyramid is properly installed After being stable and completely covered, the life span can reach more than 200 years. The characteristics of 　　 composite geomembrane: the original material of the anti-wetting composite geomembrane does not attract moisture, and the bag will never be destroyed when moisture emerges, and the bag will never be deformed and is insoluble in contaminated solids. The low temperature and high temperature resistant composite geomembrane can accept a low temperature of 150 degrees Celsius without melting, and can accept a minimum temperature of -40 degrees Celsius.
