　　Composite geomembrane, also known as composite geomembrane (one fabric, one membrane, two fabrics, one membrane), is widely used in channel anti-seepage engineering. The extensive application and effectiveness of geosynthetic materials in civil engineering, especially in flood control and emergency engineering, have attracted high attention from engineering and technical personnel. For the application technology of geosynthetics, the country has put forward standardized technical requirements from aspects such as anti-seepage, filtration, drainage, reinforcement, and protection, greatly accelerating the promotion and application of new materials. This material has been widely used in the anti-seepage engineering of irrigation channels. Based on construction practice, this article briefly discusses the application technology of composite geomembranes. Yunnan 400g composite geotextile with two fabrics and one membrane geotextile.

　　Composite geomembrane is an impermeable material composed of geotextile and geomembrane. It is mainly used for anti-seepage. Geotextiles with two fabrics and one membrane are divided into one fabric and one membrane and two fabrics and one membrane, with a width of 4-6m and a weight of 200-1500g/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, tunnel, etc. Due to the use of polymer materials and the addition of anti-aging agents in the production process, it can be used in unconventional temperature environments.

　　Precautions for construction of composite geomembrane:

　　1. Two fabrics and one membrane geotextile is formed by heating one or both sides of a thin film in a far-infrared oven, and pressing the geotextile and geotextile together through a guide roller to form a composite geotextile. With the improvement of production technology, there is also a casting method for making composite geomembranes. Its forms include one cloth and one film, two cloths and one film, two films and one cloth, etc. Jilin 400g anti-seepage geotextile with two fabrics and one membrane impermeable geotextile.

　　2. A protective layer of geotextile with two fabrics and one film to prevent damage to the anti-seepage layer. In order to reduce the ultraviolet radiation and increase the anti-aging performance, the embedding method is adopted.

　　In the construction of composite geomembranes, the first step is to use smaller diameter sand or clay to level the base surface, and then lay the composite geomembrane. Two fabrics and one membrane geotextile should not be stretched too tightly. The two ends should be buried in the soil in a corrugated shape, and then a layer of about 10cm transition layer should be laid on the composite geotextile membrane with fine sand or clay. Build 20-30cm stone blocks (or precast concrete blocks) as a protective layer against erosion. During construction, efforts should be made to avoid stones directly hitting the geotextile with two layers of fabric and one membrane. The protective layer should be constructed while laying the membrane. The connection between composite geomembrane and surrounding structures should be anchored with expansion bolts and steel plate pressure strips. The connection area should be coated with emulsified asphalt (2mm thick) for bonding to prevent leakage. Yunnan 400g composite geotextile with two fabrics and one membrane geotextile.
