High strength polypropylene staple fiber needled geotextile
1.Product description:
Composite geomembrane: Composite geomembrane is an impermeable material composed of geotextile and geomembrane, which is mainly used for seepage prevention. Composite geomembrane is divided into one cloth one membrane and two cloth one membrane, with a width of 4-6 meters, and a weight of 200-1500 g/m2. It has high physical and mechanical performance indicators such as tensile strength, tear resistance, and bursting resistance, and can meet the needs of civil engineering such as water conservancy, municipal engineering, construction, transportation, subway, and tunnel. Due to the selection of polymer materials and the addition of anti aging agents in the production process, it can be used in unconventional temperature environments. Two cloth and one membrane are composite impervious geomaterials. It is made by laminating a layer of polyethylene impermeable membrane with waterproof function on a nonwoven geotextile. The geotextile can protect the impermeable membrane from damage, thereby playing a waterproof and impermeable role. It is mainly used in various reinforced impermeable projects such as water conservancy, transportation, tunnels, airports, metallurgical tailings, garbage disposal sites, roof impermeability, and so on.

3.Application scenario:
Environmental protection and sanitation projects (such as domestic garbage landfills, sewage treatment plants, toxic and harmful substances treatment sites, hazardous goods warehouses, factories, etc.);
Water conservancy and civil engineering (seepage prevention, leakage stoppage, reinforcement, seepage prevention of canals, vertical core walls, slope protection, etc.);
Municipal engineering (subway, underground engineering of buildings, roof water storage tanks, roof garden seepage prevention, sewage pipe lining, etc.);
Landscape greening (artificial lakes, ponds, pond bottom lining of golf courses, slope protection, etc.);
Petrochemical (anti seepage and pollution prevention of oil storage tanks in chemical plants and refineries, lining and secondary lining of chemical reaction tanks and sedimentation tanks);
Mining (washing pond, heap leaching pond, ash dump, tailings dam seepage prevention and pollution prevention, etc.);
Traffic facilities engineering (foundation reinforcement of highways, seepage prevention of culverts);
Agriculture (seepage prevention of reservoirs, drinking water pools, water storage ponds, and irrigation systems);
Aquaculture (lining of fish ponds and shrimp ponds), etc.
4.Construction specification:
The geotextile serves as the protective layer of the geomembrane to protect the impermeable layer from damage. In order to reduce the ultraviolet radiation and increase the anti-aging performance, it is best to use the embedding method for laying. During construction, first use sand or clay with a smaller material diameter to level the base surface, and then lay it. When laying, do not strain it too tightly. The parts buried in the soil at both ends are corrugated. Finally, use fine sand or clay to lay a transition layer of about 10 cm on the two cloth and one film paved. Build a 20-30cm block stone (or precast concrete block) as a protective layer against erosion. During construction, it is best to avoid direct impact of stones, and to construct a protective layer while paving the membrane. The connection between two cloth and one membrane and surrounding structures should be anchored with expansion bolts and steel plate beads. The connection part should be coated with emulsified asphalt (2mm thick) for bonding to prevent leakage. Construction joint treatment is a key process that directly affects the seepage prevention effect. General joint methods include: 1. overlapping: the overlapping width should be greater than 15cm; 2. Hot welding: suitable for slightly thick geomembrane substrate, with a weld overlap width of not less than 5 cm (Adhesive bonding is not recommended, as it is easy to open after prolonged immersion in water, resulting in poor anti-seepage effect.)
